passwd: A Go repository from simukti

passwd

A Golang wrapper for hashing and validating password based on :

Libsodium Argon2i (C wrapper)
Libsodium Scrypt (C wrapper)
Bcrypt

Further details :

Argon2 is the winner of Password Hashing Competition
Bcrypt is a good old friend for dev.

Requirements

This package require libsodium >= 1.0.10 and currently tested on OSX libsodium via brew install libsodium

OSX :
- brew update
- brew install libsodium
Linux :
- Download and install libsodium from its website (https://download.libsodium.org/libsodium/content/installation/)

Install

go get -u -v github.com/simukti/passwd

Example

Argon2i

// default mode is interactive
hashed, _ := passwd.Argon2iPasswordHash([]byte(pwd))

// OR with custom operation
p := passwd.Argon2iPassword{
    Operation: Argon2iOpsLimitModerate,
    Memory:    Argon2iMemLimitModerate,
}

hashed, _ := p.Argon2iHash([]byte(pwd))

Scrypt

// default mode is interactive
hashed, _ := passwd.ScryptPasswordHash([]byte(pwd))

// OR with custom operation
p := passwd.ScryptPassword{
    Operation: ScryptOpsLimitSensitive,
    Memory:    ScryptMemLimitSensitive,
}

hashed, _ := p.ScryptHash([]byte(pwd))

Bcrypt

// using default cost (12)
hashed, _ := passwd.BcryptPasswordHash([]byte(pwd))

// OR with custom bcrypt cost
p := passwd.BcryptPassword{
    Cost: 10, // default bcrypt cost is 10
}

hashed, ok := p.BcryptHash([]byte(pwd))
