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

This package calculates CRC64 checksums using carryless-multiplication accelerated with SIMD instructions for both ARM and x86. The code is based on the https://github.com/awesomized/crc64fast-nvme.git, crc64fast-nvme package in Rust.

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

Obfs4 is a look-like nothing obfuscation protocol that incorporates ideas and concepts from Philipp Winter's ScrambleSuit protocol.

The notable differences between ScrambleSuit and obfs4 are:

• 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 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.

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.

noise implements the Noise protocol framework. Noise is a low-level framework for building crypto protocols. Noise protocols support mutual and optional authentication, identity hiding, forward secrecy, zero round-trip encryption, and other advanced features.

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

This package implements the edwards25519 elliptic curve in Go, exposing the necessary APIs to build a wide array of higher-level primitives.

Accelerate SHA256 computations in pure Go using AVX512 and AVX2 for Intel and ARM64 for ARM. On AVX512 it provides an up to 8x improvement (over 3 GB/s per core) in comparison to AVX2.

This package is designed as a replacement for crypto/sha256. For Intel CPUs it has two flavors for AVX512 and AVX2 (AVX/SSE are also supported). For ARM CPUs with the Cryptography Extensions, advantage is taken of the SHA2 instructions resulting in a massive performance improvement.

This package uses Golang assembly. The AVX512 version is based on the Intel's "multi-buffer crypto library for IPSec" whereas the other Intel implementations are described in "Fast SHA-256 Implementations on Intel Architecture Processors" by J. Guilford et al.

This package implements a subset of PKCS #7 / Cryptographic Message Syntax (RFC 2315, RFC 5652).

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

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

This package implements the pseudo-random-function (PRF) HighwayHash. HighwayHash is a fast hash function designed to defend hash-flooding attacks or to authenticate short-lived messages.

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

Package shuffle provides primitives for shuffling slices and user-defined collections.

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

This package implements RFC 7512 - the PKCS #11 URI Scheme; and errata specifications.

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

This package provides ShāngMì 4 cipher suites implementation (GM SM2/3/4).

Main functions:

• SM2 national secret elliptic curve algorithm library

• SM3 national secret hash algorithm library

• SM4 national secret block cipher algorithm 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.
