About this tool
This page opens the hash generator with SHA-256 listed first in the results — enter text or drop a file and the 64-character digest is ready to copy.
SHA-256 is today's default integrity hash: it verifies software downloads, seals certificates and blockchain blocks, and is the checksum most vendors publish next to their releases.
The tool also produces MD5, SHA-1 and SHA-512 in the same run and can compare against an expected value — computed locally in your browser, nothing leaves your machine.
Example. The UTF-8 text hello has SHA-256 digest 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824.
Limit. The algorithms computed are MD5, SHA-1, SHA-256, and SHA-512; SHA-3 is not among them.
