Signature Verification

hash, HMAC, RSA, and ECDSA checks

Verify message digests, HMAC-SHA256 values, and raw public-key signatures locally in the browser without sending data to an external service.

How it works

Digest and HMAC checks run with local JavaScript hashing. Public-key verification uses browser WebCrypto for RSA PKCS#1 v1.5, RSA-PSS, and ECDSA P-256 signatures. OpenPGP armored signatures require a dedicated OpenPGP parser and are not enabled yet.

usage: verify <md5|sha1|sha256> <expected> <text>

$ verify md5 5d41402abc4b2a76b9719d911017c592 hello
$ verify sha256 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 hello
$ verify hmac-sha256 secret <expected-hex> message

Public-key RSA/ECDSA verification is available on the tool page form. OpenPGP armor needs an OpenPGP parser and is not enabled yet.
