argon

Overview ¶

Package argon provides secure Argon2 password hashing functionality. It supports both Argon2id (recommended) and Argon2i variants with configurable parameters.

Argon2 is a memory-hard key derivation function that won the Password Hashing Competition and is resistant to both time-memory trade-off attacks and side-channel attacks.

Example usage:

// Hash a password with default configuration
hash, err := argon.GenerateHashedPassword("mypassword", argon.DefaultConfig)
if err != nil {
	log.Fatal(err)
}

// Verify a password
valid, err := argon.CompareHashAndPassword(hash, "mypassword")
if err != nil {
	log.Fatal(err)
}
if valid {
	fmt.Println("Password is correct")
}
