Package ssh wraps the crypto/ssh package with a higher-level API for building SSH servers. The goal of the API was to make it as simple as using net/http, so the API is very similar. It's alternative fork of https://github.com/gliderlabs/ssh.

Shapeshifter-Transports is a set of Pluggable Transports implementing the Go API from the Pluggable Transports 2.0 specification. Each transport implements a different method of shapeshifting network traffic. The goal is for application traffic to be sent over the network in a shapeshifted form that bypasses network filtering, allowing the application to work on networks where it would otherwise be blocked or heavily throttled.

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

This package provides primitives for generating random values.

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

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

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

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.

Package pinentry provides a client to GnuPG's pinentry.

ZLint is a X.509 certificate linter that checks for consistency with standards (e.g. RFC 5280) and other relevant PKI requirements (e.g. CA/Browser Forum Baseline Requirements).

This package provides Abstract Syntax Notation One BER encoding and decoding in the Go language.

This package provide a community managed collection of test vectors that can be used by cryptography library developers to test against known attacks, specification inconsistencies, and other various implementation bugs.

The purpose of this package is to provide a version of arbitrary sized arithmetic, in a safer (i.e. constant-time) way, for cryptography.

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 Google City Hash, originated from https://github.com/zhenjl/cityhash and https://github.com/zentures/cityhash projects.

Package ssh wraps the crypto/ssh package with a higher-level API for building SSH servers. The goal of the API was to make it as simple as using net/http, so the API is very similar.

Go-Bloom implements bloom filter using double hashing.

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

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

Package dongle is a simple, semantic and developer-friendly Golang crypto package.

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.

Bigmod is a constant-time library for big integers modulo a prime, usable for cryptographic applications. Exported from crypto/internal/bigmod, the backend of crypto/rsa and crypto/ecdsa.

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.
