This package is an external copy of the Go standard library's internal ChaCha20 package.

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

Boiler-plate to securely seed Go's random number generator (if possible).

Go-ShadowSocks is a Go implementation of the Shadowsocks tunnel proxy protocol.

This is a SIMD accelerated MD5 package, allowing up to either 8 (AVX2) or 16 (AVX512) independent MD5 sums to be calculated on a single CPU core.

md5-simd integrates a similar mechanism as described in minio/sha256-simd for making it easy for clients to take advantages of the parallel nature of the MD5 calculation. This will result in reduced overall CPU load.

This native Go library manages secrets via the freedesktop.org Secret Service DBus interface.

This package provides a Go implementation of JSON Web Tokens and supports the parsing and verification as well as the generation and signing of JSON Web Tokens. The currently supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.

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

This package is a Go library for creating a unique hash value for arbitrary values in Go. This can be used to key values in a hash (for use in a map, set, etc.) that are complex. The most common use case is comparing two values without sending data across the network, caching values locally (de-dup), and so on.

Package agent implements the ssh-agent protocol, and provides both a client and a server. The client can talk to a standard ssh-agent that uses UNIX sockets, and one could implement an alternative ssh-agent process using the sample server.

This package provides primitives for generating random values.

Native Go implementation of Austin Appleby's third MurmurHash revision (aka MurmurHash3). Reference algorithm has been slightly hacked as to support the streaming mode required by Go's standard Hash interface.

This package implements file encryption according to the https://age-encryption.org/v1 specification. It features small explicit keys, no configuration options, and Unix-style composability. This package provides a command line interface (CLI) tools.

This package provides a Go library for generating, decoding, and encrypting JSON Web Tokens (JWT). It relies only on the standard library.

This package provides a Go implementation of Google City Hash, originated from https://github.com/zhenjl/cityhash and https://github.com/zentures/cityhash projects.

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.

This package provides a Go library for the Concise Binary Object Representation (CBOR) Object Signing and Encryption (COSE) specification.

This package provides an implementation of the PKCS#11 API. It wraps the library closely, but uses Go idiom where it makes sense. It has been tested with SoftHSM.

CIRCL (Cloudflare Interoperable, Reusable Cryptographic Library) is a collection of cryptographic primitives written in Go. The goal of this library is to be used as a tool for experimental deployment of cryptographic algorithms targeting Post-Quantum (PQ) and Elliptic Curve Cryptography (ECC).

This package provides a large set of test vectors for the age file encryption format, as well as a framework to easily generate them.

The test suite can be applied to any age implementation, regardless of the language it's implemented in, and the level of abstraction of its interface. For the simplest, most universal integration, the implementation can just attempt to decrypt the test files, check the operation only succeeds if expect is success, and compare the decrypted payload. Test vectors involving unimplemented features (such as passphrase encryption or armoring) can be ignored.

Package keccak implements the Keccak (SHA-3) hash algorithm. See http://keccak.noekeon.org.

The pgpmail package implements PGP encryption for e-mail messages.

blake3 implements the BLAKE3 cryptographic hash function. In addition to the pure-Go implementation, this package also contains AVX-512 and AVX2 routines (generated by avo) that greatly increase performance for large inputs and outputs.

This package provides a hashing function.
