About this tool

Cryptographic hash functions transform input data of any size into a fixed-size output (hash digest) that is unique to that input. Our Hash Generator supports SHA-1 (160-bit, deprecated for security), SHA-256 (256-bit, current standard), SHA-384 (384-bit), and SHA-512 (512-bit, fastest on 64-bit processors). Hash text directly or upload any file for hashing. The built-in hash comparison feature lets you paste an expected hash to verify file integrity — essential for verifying software downloads, checking data integrity, and validating file transfers. All hashing uses the Web Crypto API (SubtleCrypto.digest) for native browser performance. Note: for password hashing, use bcrypt or Argon2 instead of SHA — general-purpose hash functions are too fast for password security.
