This package provides a library for reading RAR archives with Golang.

Fastzip is an opinionated Zip archiver and extractor with a focus on speed. Features:

• archiving and extraction of files and directories can only occur within a specified directory

• permissions, ownership (uid, gid on linux/unix) and modification times are preserved

• buffers used for copying files are recycled to reduce allocations

• files are archived and extracted concurrently

• by default, github.com/klauspost/compress/flate library is used for compression and decompression

Package compress is a collection of compression libraries implementing Golang modules:

brotli

Implements the Brotli format, described in RFC 7932.

bzip2

Implements the BZip2 compressed data format.

flate

Implements the DEFLATE format, described in RFC 1951.

xflate

Implements the XFLATE format, an random-access extension to DEFLATE.

lz4 provides a streaming interface to LZ4 data streams as well as low level compress and uncompress functions for LZ4 data blocks. The implementation is based on the reference C one.

Go-Bloom implements bloom filter using double hashing.

This package provides a functionality to communicate directly with a Trusted Platform Module device. The libraries don't implement the entire spec for neither 1.2 nor 2.0.

Included submodules:

• tpm - TPM 1.2 client library

• tpm2 - TPM 2.0 client library.

• direct - the prototype "TPMDirect" TPM 2.0 API, which is intended to (eventually) be 1:1 with the TPM 2.0 spec

Multihash implementation in Go.

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

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

Package pinentry provides a client to GnuPG's pinentry.

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

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

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.

Package ed25519 implements the Ed25519 signature algorithm.

This package provides a Go library for generating, decoding, and encrypting JSON Web Tokens (JWT). It relies only on the standard library.

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

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

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

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.

PKI based identities for use in go-libp2p.

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

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.

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.
