Frequently Asked Questions

A hash function takes an input (or 'message') and returns a fixed-size string of bytes. The output, typically a sequence of hexadecimal characters, is unique to the given input. Common hash functions include MD5, SHA-1, and SHA-256.

MD5 hashes are exactly 32 hexadecimal characters long (e.g., 5d41402abc4b2a76b9719d911017c592), while SHA-1 produces 40 hex characters. This tool automatically detects length and patterns to suggest the most likely hash type.

Several hash algorithms produce a 32‑hex output, such as MD5, NTLM, MD4, and MD2. Without additional context (like the source system), the exact algorithm cannot be determined by length alone. The tool lists all candidates.

Yes, a standard bcrypt hash (e.g., $2b$10$...) is 60 characters long. It includes a version prefix, cost factor, and a 53‑character salt/hash combination. This tool recognizes prefixes $2a$, $2b$, and $2y$.

No, this tool only identifies the likely hash type based on format. It does not attempt to reverse the hash or check against known databases. For security testing, always work with your own test data.

A salt is random data added to the input of a hash function to ensure that the same password produces different hashes across different systems. Bcrypt and SHA-512 crypt hashes include built-in salts, making them harder to crack.
