crypto_generate_hash
Use this when you need to generate a cryptographic hash of text. Supports md5, sha1, sha256, sha512, and bcrypt algorithms. Returns the hash string, algorithm used, and hash length. Do NOT use for password strength checking — use security_check_password. Do NOT use for data validation — use data_validate_json.
Parameters
