About Password Hash Identifier
Password Hash Identifier is used to identify which hashing algorithm produced a given password hash (bcrypt, MD5, SHA-256, Argon2, etc.). It matches the hash's format, prefix, and length against known patterns to identify the most likely algorithm. If you're storing user passwords, always use a slow, salted algorithm like bcrypt, Argon2, or scrypt — never plain MD5 or SHA. Password Hash Identifier runs entirely in your browser at abovetool.com — keys, passwords, and file contents never leave your device.
