Identify unknown hash algorithms (MD5, SHA-256, bcrypt, Argon2) with Hashcat and John modes.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Paste any unknown hash string into the analysis box.
The tool analyzes character length, hexadecimal/base64 charset, and matches known hash algorithms.
View Hashcat mode numbers, John the Ripper formats, and cryptographic security ratings.
Hashes have distinct mathematical characteristics including output bit lengths (e.g. 128-bit MD5 is always 32 hex chars, 256-bit SHA-256 is 64 hex chars) and unique modular crypt format prefixes ($2a$, $argon2id$, $6$).
MD5 and SHA-1 have proven practical collision vulnerabilities where two different inputs produce identical hash outputs, making them unsafe for cryptographic signatures.
