This package is an Ed25519 based public-key signature system that simplifies keys and seeds and performs signing and verification.

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

pcg is a random number generator that uses Permuted Congruential Generator (PCG) algorithm.

pkcs8 implements functions to process private keys in PKCS#8 format, as defined in RFC 5208 and RFC 5958. It can handle both unencrypted PKCS#8 PrivateKeyInfo format and EncryptedPrivateKeyInfo format with PKCS#5 (v2.0) algorithms.

This package provides ssh-to-pgp: a Go command line +utility to convert SSH RSA keys to GPG keys.

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.

This is a pure Go implementation of the group operations on the Ristretto prime-order group built from Edwards25519.

Package scrypt provides a convenience wrapper around Go's existing crypto/scrypt package that makes it easier to securely derive strong keys from weak inputs (i.e. user passwords). The package provides password generation, constant-time comparison and parameter upgrading for scrypt derived keys.

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

This package provides a avo vectorized version of BLAKE3 implementation in Golang.

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

Package sha1cd implements collision detection based on the whitepaper Counter-cryptanalysis from Marc Stevens. The original ubc implementation was done by Marc Stevens and Dan Shumow, and can be found at: @urlhttps://github.com/cr-marcstevens/sha1collisiondetection,https://github.com/cr-marcstevens/sha1collisiondetection.

This library is a JWT implementation that uses nkeys to digitally sign JWT tokens. Nkeys use Ed25519 to provide authentication of JWT claims.

obfs4proxy is a tool that attempts to circumvent censorship by transforming the Tor traffic between the client and the bridge. This way censors, who usually monitor traffic between the client and the bridge, will see innocent-looking transformed traffic instead of the actual Tor traffic.

This package provides an extract bcrypt from golang.org/x/crypto/bcrypt.

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

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

Package xxhash implements the 64-bit variant of xxHash (XXH64) as described at https://xxhash.com/.

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.

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 package provides a drop-in replacement of the Golang standard encoding/base64 library.

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.

Package imohash implements a fast, constant-time hash for files. It is based atop murmurhash3 and uses file size and sample data to construct the hash.
