This package provides tools for operating system dependent X.509 stores, storage methods, and accessors.

This package provides a simple monadic parser for ASN1 stream types, when ASN1 pattern matching is not convenient.

This package provides Haskell tools for X.509 certificate and Certificates revocation list (CRL) validation.

This Haskell package provides a test framework for hash and cipher operations using the crypto-api interface. Known answer tests (KATs) for common cryptographic algorithms are included.

This package provides functions for accessing and storing X.509 collections, certificates, revocation lists, and exception lists.

This Haskell package provides implementation of MD5.

This package provides a cross-platform library that tries to find a (reasonable) CA certificate bundle that can be used with HsOpenSSL to verify the certificates of remote peers. It is for HsOpenSSL what x509-system is for the tls package, and borrows some ideas from x509-system.

This package provides a Haskell-only implementation of the MD5 digest (hash) algorithm. This now supports the crypto-api class interface.

This package provides conduit interfaces for some of cryptonite's implementations of cryptographic primitives.

The package provides the standard types for dealing with the ASN.1 format.

This module provides Haskell bindings and extensions to the curve25519-donna codebase. It's a pretty straightforward implementation of the basic cryptographic routines you'd want from a project that uses curve25519: key generation, and key agreement. For further functionality, you'll want to look elsewhere.

This Haskell package provides an incremental and one-pass, pure API to the SHA-256 cryptographic hash algorithm, with performance close to the fastest implementations available in other languages.

The implementation is made in C with a haskell FFI wrapper that hides the C implementation.

This package provides a repository of cryptographic primitives.

Simple cryptographic random related types: a safe abstraction for CPRNGs.

This package provides a library to handle system accessors and storage for X.509 certificates.

This library provides readers and writers for the Privacy Enhanced Mail (PEM) format.

This Haskell package provides a platform independent method to obtain cryptographically strong entropy.

This Haskell package provides basic typeclasses and types for symmetric ciphers.

This Haskell package provides a generic interface for cryptographic operations (hashes, ciphers, randomness).

Maintainers of hash and cipher implementations are encouraged to add instances for the classes defined in Crypto.Classes. Crypto users are similarly encouraged to use the interfaces defined in the Classes module.

Any concepts or functions of general use to more than one cryptographic algorithm (ex: padding) is within scope of this package.

This library implements the SHA suite of message digest functions, according to NIST FIPS 180-2 (with the SHA-224 addendum), as well as the SHA-based HMAC routines. The functions have been tested against most of the NIST and RFC test vectors for the various functions. While some attention has been paid to performance, these do not presently reach the speed of well-tuned libraries, like OpenSSL.

HsOpenSSL is an OpenSSL binding for Haskell. It can generate RSA and DSA keys, read and write PEM files, generate message digests, sign and verify messages, encrypt and decrypt messages. It has also some capabilities of creating SSL clients and servers. This package is in production use by a number of Haskell based systems and stable. You may also be interested in the tls package, http://hackage.haskell.org/package/tls, which is a pure Haskell implementation of SSL.

This Haskell package provides an incremental and one-pass, pure API to the SHA-1 hash algorithm, including HMAC support, with performance close to the fastest implementations available in other languages.

The implementation is made in C with a haskell FFI wrapper that hides the C implementation.

This package provides a backend for the http-client package using the connection and TLS libraries. It is intended for use by higher-level libraries, such as http-conduit.

This package provides a data type and ToJSON/FromJSON instances for Bower's package manifest file, bower.json.
