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 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).

Shapeshifter-IPC is a library for Go implementing the IPC protocol from the Pluggable Transports 2.0 specification.

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

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 dictionary for TLS written in Go providing bidirectional mapping values to their names, plus enum convenience for values.

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.

Various cryptographic utilities used by IPFS

Fast implementation of base58 encoding on Golang. A trivial big.Int encoding benchmark results in 6 times faster encoding and 8 times faster decoding.

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.

SipHash is a family of pseudorandom functions (PRFs) optimized for speed on short messages.

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.

Package btcec implements elliptic curve cryptography needed for working with Bitcoin (secp256k1 only for now). It is designed so that it may be used with the standard crypto/ecdsa packages provided with Go. A comprehensive suite of test is provided to ensure proper functionality. Package btcec was originally based on work from ThePiachu which is licensed under the same terms as Go, but it has significantly diverged since then. The btcsuite developers original is licensed under the liberal ISC license.

Although this package was primarily written for btcd, it has intentionally been designed so it can be used as a standalone package for any projects needing to use secp256k1 elliptic curve cryptography.

Package whirlpool implements the ISO/IEC 10118-3:2004 whirlpool cryptographic hash as specified in http://www.larc.usp.br/~pbarreto/WhirlpoolPage.html.

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.

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

Package knownhosts is a thin wrapper around golang.org/x/crypto/ssh/knownhosts, adding the ability to obtain the list of host key algorithms for a known host.

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.

Package ed25519 implements the Ed25519 signature algorithm.

This package provides a Go translation of the reference C++ code for MetroHash, a high quality, high performance hash algorithm.

Go-Bloom implements bloom filter using double hashing.

This package implements functionality based on ideas and concepts from Philipp Winter's ScrambleSuit protocol. The notable differences between ScrambleSuit and obfs4:

• the handshake always does a full key exchange (no such thing as a Session Ticket Handshake)

• the handshake uses the Tor Project's ntor handshake with public keys obfuscated via the Elligator 2 mapping

• the link layer encryption uses NaCl secret boxes (Poly1305/XSalsa20)

Package blake256 implements BLAKE-256 and BLAKE-224 with SSE2, SSE4.1, and AVX acceleration and zero allocations.

This package provides AES Cipher Block Chaining CipherText Stealing encryption and decryption methods.
