A Golang library to verify Minisign signatures.

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.

The bsaes is a portable pure-Go constant time AES implementation based on the code from BearSSL. On appropriate systems, with a sufficiently recent Go runtime, it will transparently call crypto/aes when NewCipher is invoked.

This package exports a super-isolated elliptic curve. Over the base field 𝔽ₚ, the curve E does not admit any isogenies to other curves.

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

This package provides a hashing function.

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

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.

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.

Various cryptographic utilities used by IPFS

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

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

Multihash implementation in Go.

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

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

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

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 implements a hash/displace minimal perfect hash function.

Package pbkdf2 implements password-based key derivation using the PBKDF2 algorithm described in RFC 2898 and RFC 8018.

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

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 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.

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

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)
