How Identificador de Hash Works
A Hash Identifier is a security reconnaissance utility used to determine the cryptographic algorithm of a given string. This tool is essential for security auditors, penetration testers, and developers identifying legacy password hashes, validating checksum types, and assessing system security posture.
The "Fingerprint" Database
The tool checks your string against known signatures defined by standards like FIPS PUB 180-4 for SHA variants and RFC 1321 for MD5:
- MD5: 32 chars, Hex (0-9, A-F).
- SHA-1: 40 chars, Hex.
- SHA-256: 64 chars, Hex.
- Bcrypt: Starts with
$2a$or$2y$, as specified in the OpenBSD Bcrypt implementation. - Argon2: Starts with
$argon2, the winner of the Password Hashing Competition (PHC).
