Change log for raaz.

0.3.7 - Nov 14, 2022

Release that supports ghc-9.4 (base 0.4.17).

0.3.6 - Dec 3, 2021

Release that supports ghc-9.2 (base 0.4.16).

0.3.5 - Oct 10, 2021

Make things more friendly for serialisation.

• Enforce Encodable instance on Digest, AuthTag, and Nounce.

• Exppose unsafeToNounce for conversion from AEAD token to Nounce.

0.3.4 - Oct 7, 2021

This is yet another release trying to work out the cabal-install

• c-files interaction.

0.3.3 - Oct 7, 2021

The core and libverse files need to be in the install include. Unfortunately there is no easy way to check this out.

0.3.2 - Oct 6, 2021

Yet another missing header file sets.

0.3.1 - Oct 6, 2021

This release ensures that missing verse.h C header files. Without that the version on hackage was unbuildable.

0.3.0 - May 20, 2021

This is a major rewrite of the raaz library with significant change in the API and internals.

• Platform requirements

  • Cabal >= 3.0.0.0
  • GHC >= 8.4

• User facing interface

  • Top level Raaz module centred around cryptographic operation instead of specific primitives. This release supports the following operations

    • message digest provided via Blake2b
    • message authentication provided via Blake2b
    • authenticated encryption via XChaCha20Poly1305

  • Explicit primitive based interface meant only for interworking with other library.

  • Dropped support for SHA1, SHA224, SHA384, HMAC, and AES-CBC, mainly to concentrate efforts and reach stable release soon.

  • Pluggable interface for primitive implementations and entropy source (recommended only for advanced users)

• Internal changes.

  • Use libverse for the low level FFI implementations. From now on newer primitives will be coded up in verse instead of hand written C/assembly. (See https://github.com/raaz-crypto/libverse/)

  • Backpack based modules and signatures instead of classes for primitive implementation. Simplifies the library and allows easy plugging in of custom implementations.

• CSPRG and Entropy

  • Entropy on linux: uses getrandom by default with flag to fall back to /dev/urandom.

  • The raaz command now exposes the sub-command entropy (just like rand) mainly for system entropy quality checking.

  • A host-endian variant of chacha20 keystream for csprg.

  • Backpack based pluggable entropy source (recommended only for advanced users).

• Type level improvements.

  • Using Data.Proxy.Proxy to get rid of some uses of undefined.

  • Primitives block sizes to type level.

  • Aligned pointer with alignment at type level.

• Other changes.

  • Cross testing implementations with the monocypher library

  • Licensing changed to Apache-2.0 OR BSD-3-Clause dual licensing.

0.2.3 - 25 April, 2021

This is a minor release just update package dependencies.

0.2.2 - 13 December, 2020

This is a minor release just update package dependencies.

• Get raaz to work with the latest ghcs.

0.2.1 - 25 March, 2019

This is a minor release just to get the latest ghc.

• Get raaz to work with latest ghcs.

0.2.0 - 24 August, 2017

• Some cpu detection builtin for GCC. Would come handy in future for selection of primitives are runtime.
• BLAKE2b, BLAKE2s added.
• system entropy: Experimental support for linux getrandom call
• removed depreciated liftSubMT from Memory.
• Got rid of the class MemoryMonad, instead introduced a more specific MemoryThread. This allows to treat monads like RT mem much like MT mem, including possibility of running an action on a sub-memory.
• combinator to randomise memory cells.
• hardened the prg so that a compromise on the current prg state will not expose previously generated data.
• OpenBSD/NetBSD: fix incorrect arc4random call.
• Basic Unix man-page for the raaz command.
• Windows support is now included. The missing pieces were system entropy and memory locking which is now available.

0.1.1 - 2nd March, 2017

• Failing build on big endian machines (#306) fixed.

0.1.0 - 28th February, 2017

• Stream cipher chacha20 added.
• Added a PRG that uses chacha20, seeded with system entropy
• Sha1 highly depreciated in view of reported collision.
• We now have super command raaz with subcommands
  • checksum: as a replacement for the old checksum executable
  • rand: for generating random bytes.

Low level changes

• Reworked alignment considerations.

  • New Alignment type

  • Ways for implementations to demand that the input buffer be aligned (mainly to facilitate more efficient SIMD implementations).

• Num instance from LengthUnit removed, Monoid instance added (See issue:#247)

0.0.2 - July 25, 2016.

This release comes with very little changes.

• Encoding: translation between formats using the translate combinator
• Encoding formats: base64
• Bug fix in base16 character verification (Commit: d6eca4c37b0b)
• Dropped isSuccessful from export list of Equality.

0.0.1 - June 21, 2016.

• Basic cryptographic types.
• Hashes: sha1, sha256, sha512, sha224, sha384 and their HMACs
• Ciphers: AES-CBC with key-sizes 128, 192 and 256
• Encoding formats: base16
