About this tool
This page opens the hash generator with SHA-1 surfaced first in the output — paste text or select a file and the 40-character SHA-1 digest is computed on the spot.
SHA-1 yields a 160-bit digest and still appears in legacy checksums, Git object ids and older signatures; you need it mainly to verify downloads or match existing SHA-1 values.
MD5, SHA-256 and SHA-512 are calculated at the same time, with a built-in checksum comparator — all locally in your browser, with full privacy.
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.
