+=============
+### Helper module for loading your native module's .node file
+
+This is a helper module for authors of Node.js native addon modules.
+It is basically the "swiss army knife" of `require()`ing your native module's
+`.node` file.
+
+Throughout the course of Node's native addon history, addons have ended up being
+compiled in a variety of different places, depending on which build tool and which
+version of node was used. To make matters worse, now the _gyp_ build tool can
+produce either a _Release_ or _Debug_ build, each being built into different
+locations.
+
+This module checks _all_ the possible locations that a native addon would be built
+at, and returns the first one that loads successfully.
+
+
+Installation
+------------
+
+Install with `npm`:
+
+``` bash
+$ npm install bindings
+```
+
+Or add it to the `"dependencies"` section of your _package.json_ file.
+
+
+Example
+-------
+
+`require()`ing the proper bindings file for the current node version, platform
+and architecture is as simple as:
+
+``` js
+var bindings = require('bindings')('binding.node')
+
+// Use your bindings defined in your C files
+bindings.your_c_function()
+```
+
+
+Nice Error Output
+-----------------
+
+When the `.node` file could not be loaded, `node-bindings` throws an Error with
+a nice error message telling you exactly what was tried. You can also check the
+`err.tries` Array property.
+
+```
+Error: Could not load the bindings file. Tried:
+ → /Users/nrajlich/ref/build/binding.node
+ → /Users/nrajlich/ref/build/Debug/binding.node
+ → /Users/nrajlich/ref/build/Release/binding.node
+ → /Users/nrajlich/ref/out/Debug/binding.node

+ → /Users/nrajlich/ref/build/default/binding.node
+ → /Users/nrajlich/ref/compiled/0.8.2/darwin/x64/binding.node
+    at bindings (/Users/nrajlich/ref/node_modules/bindings/bindings.js:84:13)
+    at Object.<anonymous> (/Users/nrajlich/ref/lib/ref.js:5:47)
+    at Module._compile (module.js:449:26)

+    at Module.load (module.js:356:32)
+    at Function.Module._load (module.js:312:12)
+    ...
+```
+
+The searching for the `.node` file will originate from the first directory in which has a `package.json` file is found.

+- This module **works only with [two's complement](https://en.wikipedia.org/wiki/Two's_complement) numbers**.
+- BIP66 doesn't check that `r` or `s` are fully valid.
+  - `check`/`decode` doesn't check that `r` or `s` great than 33 bytes or that this number represent valid point on elliptic curve.
+  - `encode` doesn't check that `r`/`s` represent valid point on elliptic curve.
+
+## Example
+
+``` javascript
+var bip66 = require('bip66')
+var r = new Buffer('1ea1fdff81b3a271659df4aad19bc4ef83def389131a36358fe64b245632e777', 'hex')

+
+[![Build Status](https://secure.travis-ci.org/indutny/bn.js.png)](http://travis-ci.org/indutny/bn.js)
+
+## Install
+`npm install --save bn.js`
+
+## Usage
+
+```js
+const BN = require('bn.js');
+
+var a = new BN('dead', 16);
+var b = new BN('101010', 2);
+
+var res = a.add(b);
+console.log(res.toString(10));  // 57047
+```
+
+**Note**: decimals are not supported in this library.
+
+## Notation
+
+### Prefixes
+
+There are several prefixes to instructions that affect the way the work. Here
+is the list of them in the order of appearance in the function name:
+
+* `i` - perform operation in-place, storing the result in the host object (on
+  which the method was invoked). Might be used to avoid number allocation costs
+* `u` - unsigned, ignore the sign of operands when performing operation, or
+  always return positive value. Second case applies to reduction operations
+  like `mod()`. In such cases if the result will be negative - modulo will be
+  added to the result to make it positive
+
+### Postfixes
+
+The only available postfix at the moment is:
+
+* `n` - which means that the argument of the function must be a plain JavaScript
+  Number. Decimals are not supported.
+
+### Examples
+
+* `a.iadd(b)` - perform addition on `a` and `b`, storing the result in `a`
+* `a.umod(b)` - reduce `a` modulo `b`, returning positive value
+* `a.iushln(13)` - shift bits of `a` left by 13
+
+## Instructions
+
+Prefixes/postfixes are put in parens at the of the line. `endian` - could be
+either `le` (little-endian) or `be` (big-endian).
+
+### Utilities
+
+* `a.clone()` - clone number
+* `a.toString(base, length)` - convert to base-string and pad with zeroes
+* `a.toNumber()` - convert to Javascript Number (limited to 53 bits)
+* `a.toJSON()` - convert to JSON compatible hex string (alias of `toString(16)`)
+* `a.toArray(endian, length)` - convert to byte `Array`, and optionally zero
+  pad to length, throwing if already exceeding
+* `a.toArrayLike(type, endian, length)` - convert to an instance of `type`,
+  which must behave like an `Array`
+* `a.toBuffer(endian, length)` - convert to Node.js Buffer (if available). For
+  compatibility with browserify and similar tools, use this instead:
+  `a.toArrayLike(Buffer, endian, length)`
+* `a.bitLength()` - get number of bits occupied
+* `a.zeroBits()` - return number of less-significant consequent zero bits
+  (example: `1010000` has 4 zero bits)
+* `a.byteLength()` - return number of bytes occupied
+* `a.isNeg()` - true if the number is negative
+* `a.isEven()` - no comments
+* `a.isOdd()` - no comments
+* `a.isZero()` - no comments
+* `a.cmp(b)` - compare numbers and return `-1` (a `<` b), `0` (a `==` b), or `1` (a `>` b)
+  depending on the comparison result (`ucmp`, `cmpn`)
+* `a.lt(b)` - `a` less than `b` (`n`)
+* `a.lte(b)` - `a` less than or equals `b` (`n`)
+* `a.gt(b)` - `a` greater than `b` (`n`)
+* `a.gte(b)` - `a` greater than or equals `b` (`n`)
+* `a.eq(b)` - `a` equals `b` (`n`)
+* `a.toTwos(width)` - convert to two's complement representation, where `width` is bit width
+* `a.fromTwos(width)` - convert from two's complement representation, where `width` is the bit width
+* `BN.isBN(object)` - returns true if the supplied `object` is a BN.js instance
+
+### Arithmetics
+
+* `a.neg()` - negate sign (`i`)
+* `a.abs()` - absolute value (`i`)
+* `a.add(b)` - addition (`i`, `n`, `in`)
+* `a.sub(b)` - subtraction (`i`, `n`, `in`)
+* `a.mul(b)` - multiply (`i`, `n`, `in`)
+* `a.sqr()` - square (`i`)
+* `a.pow(b)` - raise `a` to the power of `b`
+* `a.div(b)` - divide (`divn`, `idivn`)
+* `a.mod(b)` - reduct (`u`, `n`) (but no `umodn`)
+* `a.divRound(b)` - rounded division
+
+### Bit operations
+
+* `a.or(b)` - or (`i`, `u`, `iu`)
+* `a.and(b)` - and (`i`, `u`, `iu`, `andln`) (NOTE: `andln` is going to be replaced
+  with `andn` in future)
+* `a.xor(b)` - xor (`i`, `u`, `iu`)
+* `a.setn(b)` - set specified bit to `1`
+* `a.shln(b)` - shift left (`i`, `u`, `iu`)
+* `a.shrn(b)` - shift right (`i`, `u`, `iu`)
+* `a.testn(b)` - test if specified bit is set
+* `a.maskn(b)` - clear bits with indexes higher or equal to `b` (`i`)
+* `a.bincn(b)` - add `1 << b` to the number
+* `a.notn(w)` - not (for the width specified by `w`) (`i`)
+
+### Reduction
+
+* `a.gcd(b)` - GCD
+* `a.egcd(b)` - Extended GCD results (`{ a: ..., b: ..., gcd: ... }`)
+* `a.invm(b)` - inverse `a` modulo `b`
+
+## Fast reduction
+
+When doing lots of reductions using the same modulo, it might be beneficial to
+use some tricks: like [Montgomery multiplication][0], or using special algorithm
+for [Mersenne Prime][1].
+
+### Reduction context
+
+To enable this tricks one should create a reduction context:
+
+```js
+var red = BN.red(num);
+```
+where `num` is just a BN instance.
+
+Or:
+
+```js
+var red = BN.red(primeName);
+```
+
+Where `primeName` is either of these [Mersenne Primes][1]:
+
+* `'k256'`
+* `'p224'`
+* `'p192'`
+* `'p25519'`
+
+Or:
+
+```js
+var red = BN.mont(num);
+```
+
+To reduce numbers with [Montgomery trick][0]. `.mont()` is generally faster than
+`.red(num)`, but slower than `BN.red(primeName)`.
+
+### Converting numbers
+
+Before performing anything in reduction context - numbers should be converted
+to it. Usually, this means that one should:
+
+* Convert inputs to reducted ones
+* Operate on them in reduction context
+* Convert outputs back from the reduction context
+
+Here is how one may convert numbers to `red`:
+
+```js
+var redA = a.toRed(red);
+```
+Where `red` is a reduction context created using instructions above
+
+Here is how to convert them back:
+
+```js
+var a = redA.fromRed();
+```
+
+### Red instructions
+
+Most of the instructions from the very start of this readme have their
+counterparts in red context:
+
+* `a.redAdd(b)`, `a.redIAdd(b)`
+* `a.redSub(b)`, `a.redISub(b)`
+* `a.redShl(num)`
+* `a.redMul(b)`, `a.redIMul(b)`
+* `a.redSqr()`, `a.redISqr()`
+* `a.redSqrt()` - square root modulo reduction context's prime
+* `a.redInvm()` - modular inverse of the number
+* `a.redNeg()`
+* `a.redPow(b)` - modular exponentiation

+[![TRAVIS](https://secure.travis-ci.org/crypto-browserify/buffer-xor.png)](http://travis-ci.org/crypto-browserify/buffer-xor)
+[![NPM](http://img.shields.io/npm/v/buffer-xor.svg)](https://www.npmjs.org/package/buffer-xor)
+
+[![js-standard-style](https://cdn.rawgit.com/feross/standard/master/badge.svg)](https://github.com/feross/standard)
+
+A simple module for bitwise-xor on buffers.
+
+
+## Examples
+
+``` javascript
+var xor = require("buffer-xor")
+var a = new Buffer('00ff0f', 'hex')
+var b = new Buffer('f0f0', 'hex')
+
+console.log(xor(a, b))
+// => <Buffer f0 0f>
+```
+
+
+Or for those seeking those few extra cycles, perform the operation in place:
+
+``` javascript
+var xorInplace = require("buffer-xor/inplace")
+var a = new Buffer('00ff0f', 'hex')
+var b = new Buffer('f0f0', 'hex')
+
+console.log(xorInplace(a, b))
+// => <Buffer f0 0f>
+// NOTE: xorInplace will return the shorter slice of its parameters
+
+// See that a has been mutated
+console.log(a)
+// => <Buffer f0 0f 0f>
+```

+
+Abstract base class to inherit from if you want to create streams implementing
+the same api as node crypto streams.
+
+Requires you to implement 2 methods `_final` and `_update`. `_update` takes a
+buffer and should return a buffer, `_final` takes no arguments and should return
+a buffer.
+
+
+The constructor takes one argument and that is a string which if present switches
+it into hash mode, i.e. the object you get from crypto.createHash or
+crypto.createSign, this switches the name of the final method to be the string
+you passed instead of `final` and returns `this` from update.

+## API
+
+### ECDSA
+
+```javascript
+var EC = require('elliptic').ec;
+
+// Create and initialize EC context
+// (better do it once and reuse it)
+var ec = new EC('secp256k1');
+
+// Generate keys
+var key = ec.genKeyPair();
+
+// Sign the message's hash (input must be an array, or a hex-string)
+var msgHash = [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ];
+var signature = key.sign(msgHash);
+
+// Export DER encoded signature in Array
+var derSign = signature.toDER();
+
+// Verify signature
+console.log(key.verify(msgHash, derSign));
+
+// CHECK WITH NO PRIVATE KEY
+
+var pubPoint = key.getPublic();
+var x = pubPoint.getX();
+var y = pubPoint.getY();
+
+// Public Key MUST be either:
+// 1) '04' + hex string of x + hex string of y; or
+// 2) object with two hex string properties (x and y); or
+// 3) object with two buffer properties (x and y)
+var pub = pubPoint.encode('hex');                                 // case 1
+var pub = { x: x.toString('hex'), y: y.toString('hex') };         // case 2
+var pub = { x: x.toBuffer(), y: y.toBuffer() };                   // case 3
+var pub = { x: x.toArrayLike(Buffer), y: y.toArrayLike(Buffer) }; // case 3
+
+// Import public key
+var key = ec.keyFromPublic(pub, 'hex');
+
+// Signature MUST be either:
+// 1) DER-encoded signature as hex-string; or
+// 2) DER-encoded signature as buffer; or
+// 3) object with two hex-string properties (r and s); or
+// 4) object with two buffer properties (r and s)
+
+var signature = '3046022100...'; // case 1
+var signature = new Buffer('...'); // case 2
+var signature = { r: 'b1fc...', s: '9c42...' }; // case 3
+
+// Verify signature
+console.log(key.verify(msgHash, signature));
+```
+
+### EdDSA
+
+```javascript
+var EdDSA = require('elliptic').eddsa;
+
+// Create and initialize EdDSA context
+// (better do it once and reuse it)
+var ec = new EdDSA('ed25519');
+
+// Create key pair from secret
+var key = ec.keyFromSecret('693e3c...'); // hex string, array or Buffer
+
+// Sign the message's hash (input must be an array, or a hex-string)
+var msgHash = [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ];
+var signature = key.sign(msgHash).toHex();
+
+// Verify signature
+console.log(key.verify(msgHash, signature));
+
+// CHECK WITH NO PRIVATE KEY
+
+// Import public key
+var pub = '0a1af638...';
+var key = ec.keyFromPublic(pub, 'hex');
+
+// Verify signature
+var signature = '70bed1...';
+console.log(key.verify(msgHash, signature));
+```
+
+### ECDH
+
+```javascript
+var EC = require('elliptic').ec;
+var ec = new EC('curve25519');
+
+// Generate keys
+var key1 = ec.genKeyPair();
+var key2 = ec.genKeyPair();
+
+var shared1 = key1.derive(key2.getPublic());
+var shared2 = key2.derive(key1.getPublic());
+
+console.log('Both shared secrets are BN instances');
+console.log(shared1.toString(16));
+console.log(shared2.toString(16));
+```
+
+three and more members:
+```javascript
+var EC = require('elliptic').ec;
+var ec = new EC('curve25519');
+
+var A = ec.genKeyPair();
+var B = ec.genKeyPair();
+var C = ec.genKeyPair();
+
+var AB = A.getPublic().mul(B.getPrivate())
+var BC = B.getPublic().mul(C.getPrivate())
+var CA = C.getPublic().mul(A.getPrivate())
+
+var ABC = AB.mul(C.getPrivate())
+var BCA = BC.mul(A.getPrivate())
+var CAB = CA.mul(B.getPrivate())
+
+console.log(ABC.getX().toString(16))
+console.log(BCA.getX().toString(16))
+console.log(CAB.getX().toString(16))
+```
+
+NOTE: `.derive()` returns a [BN][1] instance.
+
+## Supported curves
+
+Elliptic.js support following curve types:
+
+* Short Weierstrass
+* Montgomery
+* Edwards
+* Twisted Edwards
+
+Following curve 'presets' are embedded into the library:
+
+* `secp256k1`
+* `p192`
+* `p224`
+* `p256`
+* `p384`
+* `p521`
+* `curve25519`
+* `ed25519`
+
+NOTE: That `curve25519` could not be used for ECDSA, use `ed25519` instead.
+
+### Implementation details
+
+ECDSA is using deterministic `k` value generation as per [RFC6979][0]. Most of
+the curve operations are performed on non-affine coordinates (either projective
+or extended), various windowing techniques are used for different cases.
+
+All operations are performed in reduction context using [bn.js][1], hashing is
+provided by [hash.js][2]
+
+### Related projects
+
+* [eccrypto][3]: isomorphic implementation of ECDSA, ECDH and ECIES for both
+  browserify and node (uses `elliptic` for browser and [secp256k1-node][4] for
+  node)

+
+The insecure [key derivation algorithm from OpenSSL.][1]
+
+**WARNING: DO NOT USE, except for compatibility reasons.**
+
+MD5 is insecure.
+
+Use at least `scrypt` or `pbkdf2-hmac-sha256` instead.
+
+
+## API
+`EVP_BytesToKey(password, salt, keyLen, ivLen)`
+
+* `password` - `Buffer`, password used to derive the key data.
+* `salt` - 8 byte `Buffer` or `null`, salt is used as a salt in the derivation.
+* `keyBits` - `number`, key length in **bits**.
+* `ivLen` - `number`, iv length in bytes.
+
+*Returns*: `{ key: Buffer, iv: Buffer }`
+
+
+## Examples
+MD5 with `aes-256-cbc`:
+
+```js
+const crypto = require('crypto')
+const EVP_BytesToKey = require('evp_bytestokey')
+
+const result = EVP_BytesToKey(
+  'my-secret-password',
+  null,
+  32,
+  16
+)
+// =>
+// { key: <Buffer e3 4f 96 f3 86 24 82 7c c2 5d ff 23 18 6f 77 72 54 45 7f 49 d4 be 4b dd 4f 6e 1b cc 92 a4 27 33>,
+//   iv: <Buffer 85 71 9a bf ae f4 1e 74 dd 46 b6 13 79 56 f5 5b> }
+
+const cipher = crypto.createCipheriv('aes-256-cbc', result.key, result.iv)
+```

+Abstract base class to inherit from if you want to create streams implementing the same API as node crypto [Hash][1] (for [Cipher][2] / [Decipher][3] check [crypto-browserify/cipher-base][4]).
+
+## Example
+
+```js
+const HashBase = require('hash-base')
+const inherits = require('inherits')
+
+// our hash function is XOR sum of all bytes
+function MyHash () {
+  HashBase.call(this, 1) // in bytes

+
+inherits(MyHash, HashBase)

+}
+
+MyHash.prototype._digest = function () {
+  return this._sum
+}
+
+const data = Buffer.from([ 0x00, 0x42, 0x01 ])
+const hash = new MyHash().update(data).digest()
+console.log(hash) // => 67

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+Node style `md5` on pure JavaScript.
+
+From [NIST SP 800-131A][1]: *md5 is no longer acceptable where collision resistance is required such as digital signatures.*
+
+## Example
+
+```js
+var MD5 = require('md5.js')
+
+console.log(new MD5().update('42').digest('hex'))
+// => a1d0c6e83f027327d8461063f4ac58a6
+
+var md5stream = new MD5()
+md5stream.end('42')
+console.log(md5stream.read().toString('hex'))
+// => a1d0c6e83f027327d8461063f4ac58a6
