Identify unknown hashes offline instantly. Our free hash detector analyzes string length and character sets to detect MD5, SHA-1, SHA-256, bcrypt, NTLM, and other formats securely in your browser.
Hash identification is probabilistic. Because many hashing algorithms output standard hexadecimal strings of identical lengths (e.g. MD5 and NTLM are both 32 characters), it is impossible to definitively distinguish between them based purely on the output. Therefore, standard hex hashes are marked as "Possible", while uniquely structured formats (like bcrypt or Argon2) are marked as "High" confidence.
No. The Hash Identifier tool operates entirely locally in your browser. Your input is analyzed using client-side regular expressions and is never transmitted over the internet.
No. This tool only identifies the format of the hash based on its length and character set. Hashes are mathematically designed to be one-way functions, meaning they cannot be simply decrypted.
