Various cryptographic utilities used by IPFS

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

Go-OpenVPN-Mgmt implements a client for the OpenVPN management interface. It can be used to monitor and control an OpenVPN process running with its management port enabled.

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

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

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.

Go-Bloom implements bloom filter using double hashing.

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

This package provides ssh-to-pgp: a Go command line +utility to convert SSH RSA keys to GPG keys.

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.

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 an command line interface (CLI) tool.

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.

This package provides a high-performance Uint128 type that supports standard arithmetic operations. Unlike math/big, operations on Uint128 values always produce new values instead of modifying a pointer receiver. A @codeUint128 value is therefore immutable, just like uint64 and friends.

Gonum is a set of packages designed to make writing numerical and scientific algorithms productive, performant, and scalable. It provides libraries for matrices and linear algebra; statistics, probability distributions, and sampling; tools for function differentiation,integration, and optimization; network creation and analysis

Package bigfft implements multiplication of big.Int using FFT (Schonhage-Strassen method for multiplying integers).

Package decimal implements an arbitrary precision fixed-point decimal. Features:

• the zero-value is 0, and is safe to use without initialization

• addition, subtraction, multiplication with no loss of precision

• division with specified precision

• database/sql serialization/deserialization

• JSON and XML serialization/deserialization

This package implements a functionality for fitting statistical model. Additional Go packages include glm for Generalized Liner Models and duration for survival analysis. All models can be fit with maximum (or quasi-maximum) likelihood estimation, with optional L1 (Lasso) or L2 (ridge) penalization.

This package provides a IEEE 754 half-precision floating-point format (binary16) with IEEE 754 default rounding for conversions. IEEE 754-2008 refers to this 16-bit floating-point format as binary16.

Package mathutil provides utilities supplementing the standard math and math/rand packages.

This package implements much of the decimal specification from the General Decimal Arithmetic description. This is the same specification implemented by Python’s decimal module and GCC’s decimal extension.

This package offers overflow-checked integer arithmetic operations for int,int32, and int64. Each of the operations returns a result,bool combination. This was prompted by the need to know when to flow into higher precision types from the math.big library.

This package implements much of the decimal specification from the General Decimal Arithmetic description. This is the same specification implemented by Python’s decimal module and GCC’s decimal extension.

gg is a plotting package for Go inspired by the Grammar of Graphics.

Package fastdiv implements fast division, modulus and divisibility checks for divisors known only at runtime based on paper: Faster Remainder by Direct Computation: Applications to Compilers and Software Libraries.
