# Change log for [raaz].
## [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 )
- 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
