0.7.0 / 2015-12-13

  • extracted bitcoinjs-lib ecdsa. Fixes a number of issues of security issues.

0.6.0 / 2014-09-30

  • dropped alternative curve support, only secp256k1 for now; if we find we need others in the future we can just grab them from Git history
  • upgraded from "ecurve": "^0.6.0"to "ecurve": "^1.0.0"

0.5.3 / 2014-07-04

  • bugfix: verify() should treat hash as a Buffer and as not a byte array, see #14

0.5.2 / 2014-07-03

  • bugfix: deterministicGenerateK() now works with BigInteger instances of other bigi installations

0.5.1 / 2014-06-03

  • mistakenly left secure-random as a production dependency, moved it to development dep

0.5.0 / 2014-06-02

  • added Travis CI support
  • added Coveralls support
  • upgraded ~ecurve@0.3.2 to ^ecurve@0.6.0
  • removed ecurve-names from dev deps
  • upgraded ~bigi@0.2.0 to ^bigi@1.1.0
  • removed sha256 from dev deps
  • changed the way the module should be used, old way was very cumbersome

New Way:

var ecdsa = require('ecdsa') //defaults to secp256k1 curve

if you want another curve:

var ecdsa = require('ecdsa')('secp256r1')
  • added deterministicGenerateK(), RFC 6979. See: #4.
  • added recoverPubKey() from BitcoinJS / Daniel Cousens
  • added serializeSigCompact() from BitcoinJS / Daniel Cousens
  • changed method signature of sign(hash, privateKeyBigInteger) to sign(hash, privateKeyBuffer)`
  • sign() method now uses low s value: See: #10
  • renamed calcPubkeyRecoveryParam() to calcPubKeyRecoveryParam(), changed signature
  • added Testling support

0.4.1 / 2014-04-14

  • bugfix: parseSigCompact() referencing invalid ecparams #6
  • bugfix: verify() works with compressed keys #9
  • add browser tests

0.4.0 / 2014-03-13

  • removed bower / component stuff. Still works with browser, just use browserify. Closes #3

  • moved from 4 spaces to 2 spaces (Node style)

  • made class based so that multiple instantiations can be made with different curves, i.e. not just tied to secp256k1. Closes #2 BREAKING CHANGE. Set ECDSA.ecparams before using ECDSA.

  • made class level methods so that existing code should work with very little modification

  • removed dependency upon ecurve-names

  • update deps: secure-random and ecurve. (will eventually removed secure-random)

0.3.0 / 2013-12-08

  • upgraded deps (for bigi)

0.2.0 / 2013-12-07

  • moved recoverPubKey() to package eckey
  • added test for verify() and sign()

0.1.0 / 2013-11-20

  • changed package name
  • removed AMD support

0.0.1 / 2013-11-12

  • initial release
