Revision history for the hashes package

0.3.0.1 -- 2024-08-20

• Fix building the package on Gentoo.

Internal Changes:

• Replace the Syd test framework by hspec.
• Modernize the FFI interface with OpenSSL.

0.3.0 -- 2024-07-12

Breaking Changes:

• Add type type parameter to support different output sizes for Shake128 and Shake256.
• Hash functions in Data.Hash.Class.Mutable and Data.Hash.Class.Mutable.Salted now run in IO, which is generally more efficient than a pure computation within unsafePerformIO. The modules also provide pure variants of the hash functions that can be used when the performance overhead of unsafePerformIO does not matter.
• Drop support for OpenSSL < 1.1.

Other Changes:

• Add support for Keccak224, Keccak384, Shake128/256,and Shake256/512.
• Improved test coverage for OpenSSL based hashes.
• Avoid deprecated API calls in the implementation of OpenSSL based hashes.
• Add an IsString instance for OpenSSL based digests that uses hex encoding.
• Improve heuristics for locating libcrypt on macOS.

0.2.3 -- 2022-11-22

• Support reset and reuse of context for OpenSSL digests.
• Avoid the use of deprecated OpenSSL methods.
• Add methods to write digests directly to a pointer for Keccak digests.

0.2.2.1 -- 2022-09-28

• Support for Apple Silicon (aarch64_HOST_ARCH)

0.2.2.0 -- 2022-08-20

• Test suite for SHA hash functions
• Fix openssl-3.0 support

0.2.1.1 -- 2021-10-23

• Fixes for building with GHC-9.2

0.2.1.0 -- 2021-10-22

• Add OpenSSL based implementation of Keccak-512.

0.2.0.0 -- 2021-10-20

Breaking changes:

• Add Class based interfaces for hash functions with pure and mutable contexts.
• Support incremental hashing.
• Provide type classes for hash functions with salt / key.
• Add utility functions for hashing ByteStrings.

Other changes:

• Provide cryptographic hash functions from OpenSSL.

0.1.0.1 -- 2021-09-30

• Support building with GHC-9.2.0-rc1

0.1.0.0 -- 2021-09-29

• First version. Released on an unsuspecting world.
