hasher

Library for easy hashing and verifying passwords.

The hashing algorithm is Argon2id.

The parameters are:

• Memory: 64 MiB
• Iterations: 1
• Parallelism: 4
• Salt length: 32

The result is:

• Hash: base64 string with length of 43
• Salt: base64 string with length of 43

Usage

Import

import (
    "github.com/salif/hasher"
)

Hash

password := "password"
hash, salt, err := hasher.Hash(password)
// save hash and salt to database if err is nil

Verify

password := "password"
// get hash and salt from database
match, err := hasher.Verify(password, hash, salt)
if err == nil && match {
    // The password is correct
}

CLI tool

Install

go get github.com/salif/hasher/cmd/hasher

Hash

hasher "password"

or

echo -n "password" | hasher

Verify

hasher "password" "hash" "salt"

or

echo -n "password" | hasher "hash" "salt"
