Native Haskell TLS and SSL protocol implementation for server and client. This provides a high-level implementation of a sensitive security protocol, eliminating a common set of security issues through the use of the advanced type system, high level constructions and common Haskell features. Currently implement the SSL3.0, TLS1.0, TLS1.1 and TLS1.2 protocol, and support RSA and Ephemeral (Elliptic curve and regular) Diffie Hellman key exchanges, and many extensions.

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 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 Haskell package provides AES cipher implementation.

The modes of operations available are ECB (Electronic code book), CBC (Cipher block chaining), CTR (Counter), XTS (XEX with ciphertext stealing), GCM (Galois Counter Mode).

The AES implementation uses AES-NI when available (on x86 and x86-64 architecture), but fallback gracefully to a software C implementation.

The software implementation uses S-Boxes, which might suffer for cache timing issues. However do notes that most other known software implementations, including very popular one (openssl, gnutls) also uses similar implementation. If it matters for your case, you should make sure you have AES-NI available, or you'll need to use a different implementation.

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

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

Simple crypto pseudo-random-number-generator with really good randomness property.

Using ent, a randomness property maker on one 1Mb sample:

• Entropy = 7.999837 bits per byte.

• Optimum compression would reduce the size of this 1048576 byte file by 0 percent.

• Chi square distribution for 1048576 samples is 237.02.

• Arithmbetic mean value of data bytes is 127.3422 (127.5 = random).

• Monte Carlo value for Pi is 3.143589568 (error 0.06 percent).

Compared to urandom with the same sampling:

• Entropy = 7.999831 bits per byte.

• Optimum compression would reduce the size of this 1048576 byte file by 0 percent.

• Chi square distribution for 1048576 samples is 246.63.

• Arithmetic mean value of data bytes is 127.6347 (127.5 = random).

• Monte Carlo value for Pi is 3.132465868 (error 0.29 percent).

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

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 provides functions for X.509 certificate and revocation list validation.

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.

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

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

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

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

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

This package provides a simple network runner library in Haskell.

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

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.

TagSoup is a library for parsing HTML/XML. It supports the HTML 5 specification, and can be used to parse either well-formed XML, or unstructured and malformed HTML from the web. The library also provides useful functions to extract information from an HTML document, making it ideal for screen-scraping.
