What is a Hash Generator?

A hash generator converts text or data into a unique, fixed-length string known as a hash. Hashes are widely used in password security, API authentication, file verification, and cryptography research.

Supported Hash Algorithms

  • Cryptographic: MD5, SHA1, SHA256, SHA512, SHA224, SHA384, SHA3 family
  • Password Hashing: bcrypt, Argon2i, Argon2id
  • Checksum / Data Integrity: CRC32, Adler32, RIPEMD160, Whirlpool, Tiger192, HAVAL256, Snefru256
