A collection of crypto hashes, with a practical incremental and one-pass, pure APIs, with performance close to the fastest implementations available in other languages. The implementations are made in C with a haskell FFI wrapper that hides the C implementation.

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

This package provides a library implementing SOCKS Protocol Version 5.

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.

This library contains io-streams routines for secure networking using OpenSSL (by way of HsOpenSSL).

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

This Haskell package provides implementation of MD5.

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

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

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

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 package is a repository of cryptographic primitives for Haskell. It supports a wide range of symmetric ciphers, cryptographic hash functions, public key algorithms, key derivation numbers, cryptographic random number generators, and more.

This package provides efficient cryptographic hash implementations for strict and lazy bytestrings. For now, CRC32 and Adler32 are supported; they are implemented as FFI bindings to efficient code from zlib.

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

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

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 reader and writer for ASN1 data in raw form with supports for high level forms of ASN1 (BER, and DER).

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 a simple, fast, self-contained copy of the Ed25519 public-key signature system with a clean interface. It also includes support for detached signatures, and thorough documentation on the design and implementation, including usage guidelines.

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 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.

Generic cryptography public keys algorithm types.

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