Text Hash Generator
Hash text or a file with MD5, SHA-1, the full SHA-2 and SHA-3 families and CRC-32 at once, in hex, base64, base64url and uppercase — with a compare box for verifying downloads.
0 bytes · UTF-8
Compute a hash first, then paste the published one here.
Available algorithms
Struck-through algorithms are not exposed by crypto.subtle in this browser — SHA-512/256 and SHA-3 vary by engine. MD5 and SHA-1 are implemented here in full.
Digests
Hash some text or a file to see every digest at once.
About this tool
MD5 and SHA-1 are implemented from the specifications in this file because Web Crypto refuses to expose them, and both are now streamed block by block so large files never need to be held in memory. SHA-256, SHA-384, SHA-512, SHA-512/256 and the SHA-3 family use crypto.subtle.digest, and CRC-32 uses a precomputed table. Everything runs locally — files are read with File.slice() and never uploaded. MD5 and SHA-1 are broken for security purposes and are offered only for checksums and legacy formats.
