Raaz: A secure cryptographic library

Apache-2.0 OR BSD-3-Clause Hackage Hackage Dependencies

Raaz is a cryptographic library in Haskell that provide a high level and safe access to a lot of cryptographic operations. The library can be used for standalone cryptographic applications as well as for implementing other network protocols. Some of the features that are unique to raaz are the following

  1. Pervasive use of types for better safety.
  2. Default choice of primitives and implementations are safe.
  3. Mechanism to have multiple implementations for any given cryptographic primitives. An advanced user who has an in-depth knowledge of the platform should be able to plugin the desired implementation.
  4. Strong emphasis on API design with thorough documentation.


The recommended way to install raaz is through cabal-install version 3.0 or above. We also need a version of GHC that supports backpack (for details on which version of GHC is supported, refer to our CI-builds).

cabal build
cabal test
cabal install
