FarmHash provides hash functions for strings and other data. The functions mix the input bits thoroughly but are not suitable for cryptography. It is implemented as a mechanical translation of the non-SSE4/non-AESNI hash functions from Google's FarmHash.

ChaCha is a stream cipher family created by Daniel Bernstein. The most common ChaCha variant is ChaCha20 (20 rounds). ChaCha20 is standardized in RFC 7539.

Multihash implementation in Go.

EME (ECB-Mix-ECB or, clearer, Encrypt-Mix-Encrypt) is a wide-block encryption mode developed by Halevi and Rogaway.

This is a native Go implementation of the xxHash algorithm, an extremely fast non-cryptographic hash algorithm, working at speeds close to RAM limits.

This provides a fork of uTLS for the specific purpose of improving obfs4proxy's meek_lite transport.

This package provides a Golang implementation of the bcrypt hash algorithm. It is a fork of github.com/jameskeane/bcrypt.

This package provides a port of the XXH3 hash algorithm to Golang. XXH3 is an extremely fast non-cryptographic hash algorithm.

This package provides cryptography for Go. This version of the package is a fork that adds a more up-to-date OpenPGP implementation. It is completely backwards compatible with golang.org/x/crypto, the official package.

This is a Go implementation of the Google Authenticator library as specified in RFC 4226 and RFC 6238.

This package implements a functionality to convert keys between the PEM and JWK file formats.

PKI based identities for use in go-libp2p.

This package implements a functionality for two parties to generate a mutual secret key by using a weak key that is known to both beforehand (e.g. via some other channel of communication). This is a simple API for an implementation of Password-Authenticated Key Exchange. This protocol is derived from Dan Boneh and Victor Shoup's cryptography book (pg 789, PAKE2 protocol).

Go-Bloom implements bloom filter using double hashing.

The purpose of this package is to provide a version of arbitrary sized arithmetic, in a safer (i.e. constant-time) way, for cryptography.

Keyring provides utility functions for and a common interface to a range of secure credential storage services. Originally developed as part of AWS Vault, a command line tool for securely managing AWS access from developer workstations.

Currently Keyring supports the following backends: macOS/OSX Keychain, Windows pcredential store, Pass, Secret Service, KDE Wallet, Encrypted File. This package provides an command line interface (CLI) tool.

This package provides extensions to the Go standard library's Ed25519 and curve25519 implementations, primarily extracted from @urlhttps://github.com/oasisprotocol/curve25519-voi,curve25519-voi. This package is intended for interoperability with the standard library and the @urlhttps://filippo.io/edwards25519,edwards25519 package as much as possible.

This package implements consistent hashing that can be used when the number of server nodes increase or decrease (like in memcached). The hashing ring is built using the same algorithm as libketama.

Package pinentry provides a client to GnuPG's pinentry.

Various cryptographic utilities used by IPFS

This package provides qtls, a QUIC-capable variant of the Go standard library's TLS 1.3 implementation.

This repository contains Go packages related to cryptographic standards that are not included in the Go standard library.

This package provides a hashing function.

Package pinentry provides a client to GnuPG's pinentry.
