Paste a hash string and see which algorithms it’s consistent with — based on length, character set, and well-known prefix markers like $2a$, $argon2id$, {SSHA}, or $1$. Useful for triaging password dumps, CTF challenges, and migration audits.
Analysis
Paste a hash above and click Identify.
Notes
Length-only matches (e.g. 32 hex chars) cannot be distinguished — many algorithms share the same digest size, so multiple candidates are returned.
Prefix markers ($id$, {SCHEME}) are diagnostic and ranked higher confidence.
This tool only identifies the format. It does not reverse the hash.
