Frequently Asked Questions
What is the Hash Identifier?
A tool that analyzes a hash string and lists candidate algorithms (MD5, SHA-1, SHA-256, bcrypt, Argon2, PBKDF2, JWT, and more) based on length, character set, and prefixes.
Is it private?
Yes — all detection is client-side regex pattern matching. Your hashes never leave your device.
Why does it show multiple candidates?
Many hashes are indistinguishable (e.g. MD5, NTLM, MD4, LM all emit 32 hex chars). Results are ranked by confidence with the corresponding Hashcat mode number.
