  • Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
    Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
    In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ??to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
