#PasswordAlgorithm

Phuture\Coherence\Enum\PasswordAlgorithm

enum PasswordAlgorithm

Enumeration for password hashing algorithm selection.

This enum defines the password hashing algorithms available when hashing or rehashing passwords. Use it with \Phuture\Coherence\Hash::password() and \Phuture\Coherence\Hash::passwordNeedsRehash() to select which algorithm to apply.

#Cases

#Argon2i

case Argon2i

Use the Argon2I algorithm.

Argon2I is a memory-hard algorithm optimized to resist side-channel attacks. It is the winner of the 2015 Password Hashing Competition. Use this when side-channel resistance is the primary concern. Requires PHP compiled with libargon2 support.

#Argon2id

case Argon2id

Use the Argon2ID algorithm.

Argon2ID is a memory-hard algorithm that provides resistance against GPU-based brute-force attacks and side-channel attacks. It is the recommended choice for new applications when available. Requires PHP compiled with libargon2 support.

#Bcrypt

case Bcrypt

Use the BCrypt algorithm.

BCrypt is a well-established password hashing algorithm that is widely supported and produces a 60-character hash. It is a safe choice when Argon2ID is not available.

#Default

case Default

Use PHP's current recommended default algorithm.

Delegates the algorithm choice to PHP itself, which always points to the most secure algorithm available in the current PHP version. This is the safest long-term choice as it automatically upgrades when PHP changes its recommended default.
