Fixed a bug in the fast version of Poly1305 and brought it back.
Thanks to @floodyberry for promptly responding and fixing the original C code:
“The issue was not properly detecting if st->h was >= 2^130 - 5, coupled with [testing mistake] not catching the failure. The chance of the bug affecting anything in the real world is essentially zero luckily, but it’s good to have it fixed.”
Switched Poly1305 fast version back to original (slow) version due to a bug.
No code changes, just tweaked packaging and added COPYING.txt.
Breaking change! All functions from
nacl.util have been removed. These functions are no longer available:
nacl.util.decodeUTF8 nacl.util.encodeUTF8 nacl.util.decodeBase64 nacl.util.encodeBase64
If want to continue using them, you can include https://github.com/dchest/tweetnacl-util-js package:
<script src="nacl.min.js"></script> <script src="nacl-util.min.js"></script>
var nacl = require('tweetnacl'); nacl.util = require('tweetnacl-util');
However it is recommended to use better packages that have wider compatibility and better performance. Functions from
nacl.util were never intended to be robust solution for string conversion and were included for convenience: cryptography library is not the right place for them.
Currently calling these functions will throw error pointing to
tweetnacl-util-js (in the next version this error message will be removed).
Improved detection of available random number generators, making it possible to use
nacl.randomBytes and related functions in Web Workers without changes.
Changes to testing (see README).
No code changes.
Reverted license field in package.json to “Public domain”.
Fixed typo in README.
Fixed undefined variable bug in fast version of Poly1305. No worries, this bug was never triggered.
Specified CC0 public domain dedication.
Updated development dependencies.
buffermodules from browserify builds.
nacl-fast the default version in NPM package. Now
require("tweetnacl") will use fast version; to get the original version, use
Cleanup temporary array after generating random bytes.
nacl.signand related functions up to 3x faster in
nacl.sign.keyPair.fromSeed to enable creation of sign key pairs deterministically from a 32-byte seed. (It behaves like libsodium’s
crypto_sign_seed_keypair: the seed becomes a secret part of the secret key.)
Fast version now has an improved hash implementation that is 2x-5x faster.
Fixed benchmarks, which may have produced incorrect measurements.
nacl.sign.opennow deal with signed messages, and new
nacl.sign returned a signature, and
nacl.sign.open accepted a message and “detached” signature. This was unlike NaCl’s API, which dealt with signed messages (concatenation of signature and message).
The new API is:
nacl.sign(message, secretKey) -> signedMessage nacl.sign.open(signedMessage, publicKey) -> message | null
Since detached signatures are common, two new API functions were introduced:
nacl.sign.detached(message, secretKey) -> signature nacl.sign.detached.verify(message, signature, publicKey) -> true | false
(Note that it’s
open, and it returns a boolean value, unlike
open, which returns an “unsigned” message.)
