Requirements

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

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))
