Crypto++ is a C++ class library of cryptographic schemes.

The currently provided message digest algorithms are:

• MD2

• MD4

• MD5

• RIPEMD-160

• SHA-1

• SHA-2 (SHA-256, SHA-384 and SHA-512)

The Olm library implements the Double Ratchet cryptographic ratchet. It is written in C and C++11, and exposed as a C API.

Keychain is usually run from shell profiles like ~/.bash_profile, but it is also possible to use it with non-interactive shells. It works with various operating systems (including GNU/Linux and HURD) and shells (like bourne-compatible, csh-compatible and fish shells). By default Keychain will only start ssh-agent, but it can also be configured to start gpg-agent.

stoken is a token code generator compatible with RSA SecurID 128-bit (AES) tokens. This package contains a standalone command-line program that allows for importing token seeds, generating token codes, and various utility/testing functions.

This module provides implementations for a number of byte-oriented sources of random data.

The Olm library implements the Double Ratchet cryptographic ratchet. This package contains its Python bindings.

CryFS encrypts your files, so you can safely store them anywhere. It works well together with cloud services like Dropbox, iCloud, OneDrive and others. CryFS creates an encrypted userspace filesystem that can be mounted via FUSE without root permissions. It is similar to EncFS, but provides additional security and privacy measures such as hiding file sizes and directory structure. However CryFS is not considered stable yet by the developers.

Optimized C library for cryptographic operations on curve secp256k1.

This library is used for consensus critical cryptographic operations on the Bitcoin Cash network.

Features:

• secp256k1 ECDSA signing/verification and key generation.

• secp256k1 Schnorr signing/verification (Bitcoin Cash Schnorr variant).

• Additive and multiplicative tweaking of secret/public keys.

• Serialization/parsing of secret keys, public keys, signatures.

• Constant time, constant memory access signing and pubkey generation.

• Derandomized ECDSA (via RFC6979 or with a caller provided function).

• Very efficient implementation.

• Suitable for embedded systems.

• Optional module for public key recovery.

• Optional module for ECDH key exchange (experimental).

• Optional module for multiset hash (experimental).

ssss-split and ssss-combine are utilities that split and combine secrets securely using Shamir's secret sharing scheme. This implementation allows for a threshold scheme where the minimum number of shares can be less than the total number of shares generated.

Minisign is a dead simple tool to sign files and verify signatures. It is portable, lightweight, and uses the highly secure Ed25519 public-key signature system. Signature written by minisign can be verified using OpenBSD's signify tool: public key files and signature files are compatible. However, minisign uses a slightly different format to store secret keys. Minisign signatures include trusted comments in addition to untrusted comments. Trusted comments are signed, thus verified, before being displayed.

Sodium is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc.

This package provides a simple password-based encryption utility as a demonstration of the scrypt key derivation function. Scrypt is designed to be far more resistant against hardware brute-force attacks than alternative functions such as PBKDF2 or bcrypt.

ISAAC (Indirection, Shift, Accumulate, Add, and Count) is a fast pseudo-random number generator. It is suitable for applications where a significant amount of random data needs to be produced quickly, such as solving using the Monte Carlo method or for games. The results are uniformly distributed, unbiased, and unpredictable unless you know the seed.

This package provides a Perl interface to the ISAAC pseudo random number generator.

Asignify offers public cryptographic signatures and encryption with a library or a command-line tool. The tool is heavily inspired by signify as used in OpenBSD. The main goal of this project is to define a high level API for signing files, validating signatures and encrypting using public-key cryptography. Asignify is designed to be portable and self-contained with zero external dependencies. Asignify can verify OpenBSD signatures, but it cannot sign messages in OpenBSD format yet.

This package provides a crate to sign files and verify signatures.

DigiDoc is an XML file format for documents with digital signatures used by the Estonian ID card infrastructure. This library allows for creation and reading of DigiDoc files.

This module is intended to provide a cryptographically-secure replacement for Perl's built-in rand function. "Cryptographically secure", in this case, means:

1. No matter how many numbers you see generated by the random number generator, you cannot guess the future numbers, and you cannot guess the seed.

2. There are so many possible seeds that it would take decades, centuries, or millennia for an attacker to try them all.

3. The seed comes from a source that generates relatively strong random data on your platform, so the seed itself will be as random as possible.

Botan is a cryptography library, written in C++11, offering the tools necessary to implement a range of practical systems, such as TLS/DTLS, PKIX certificate handling, PKCS#11 and TPM hardware support, password hashing, and post-quantum crypto schemes. In addition to the C++, botan has a C89 API specifically designed to be easy to call from other languages. A Python binding using ctypes is included, and several other language bindings are available.

This package provides b3sum, a command line checksum tool based on the BLAKE3 cryptographic hash function.

BLAKE2 is a cryptographic hash function faster than MD5, SHA-1, SHA-2, and SHA-3, yet is at least as secure as SHA-3.
