- Add salt/personalisation strings for Blake2b ([#105])

## 3.2.0 (2015-05-31)

- Fix method signature for blake2b
- RuboCop-friendly codebase

## 3.1.2 (2014-08-30)

- Fix scrypt support with libsodium 0.7.0 (scryptsalsa208sha256)

## 3.1.1 (2014-06-14)

- Fix undefined variable warning
- RSpec 3 fixups
- RuboCop

## 3.1.0 (2014-05-22)

- The scrypt password hashing function: `RbNaCl::PasswordHash.scrypt`

## 3.0.1 (2014-05-12)

- Load gem from `RBNACL_LIBSODIUM_GEM_LIB_PATH` if set. Used by rbnacl-libsodium
  gem to use libsodium compiled from a gem.

## 3.0.0 (2014-04-22)

- Rename RandomNonceBox to SimpleBox (backwards compatibility preserved)
- Reverse documented order of SimpleBox/RandomNonceBox initialize parameters.
  Technically backwards compatible, but confusing.
- Ensure all strings are ASCII-8BIT/BINARY encoding prior to use

## 2.0.0 (2013-11-07)

- Rename Crypto module to RbNaCl module
- Add encrypt/decrypt aliases for `Crypto::RandomNonceBox`
- `RbNaCl::VerifyKey#verify` operand order was reversed. New operand order is
  signature, message instead of message, signature
- `RbNaCL::SecretBox#open`, `RbNaCl::Box#open`, `Auth#verify` and
  `VerifyKey#verify` all now raise a (descendent of) CryptoError if the check
  fails.  This ensures failures are handled by the program.
- `RbNaCl::SecretBox`, Box, etc. are all now aliases for the real
  implementations, which are named after the primitives they provide
- Removed encoder functionality.
- Add support for the Blake2b cryptographic hash algorithm.
- Add checks that we have a sufficiently recent version of libsodium (0.4.3+)
- Dropped ruby-1.8 support
- Call the `sodium_init()` function, to select the best algorithms.
- Fix some typos in the documentation
- Changes in the low level binding for libsodium and removal of the NaCl module
- Add a mutex around calls to randombytes in libsodium

## 1.1.0 (2013-04-19)

- Provide API for querying primitives and details about them, such as key
  lengths, nonce lengths, etc.
- Fixed bug on passing null bytes to sha256, sha512 functions.

## 1.0.0 (2013-03-08)
