Run util/openssl-format-source -v -c . In order to reduce cluttering of the global manual page namespace, the manual page entries without the 'openssl-' prefix have been deprecated in OpenSSL 3.0 and will be removed in OpenSSL 4.0. openssl enc -base64 -d -in sign.txt.sha256.base64 -out sign.txt.sha256 openssl dgst -sha256 -verify public.key.pem -signature sign.txt.sha256 codeToSign.txt Conclusion So that’s it, with either the OpenSSL API or the command line you can sign and verify a code fragment to ensure that it has not been altered since it was authored. You *must* use EVP_PKEY_assign_RSA() or similar in 1.0.0 as other structures get initialised at the same time. blob | commitdiff | raw | diff to current: 2014-12-30: Thorsten Glaser: Document openssl dgst -hmac option: blob | commitdiff | raw | diff to current: 2014-06-29: Dr. Stephen Henson: Don't core dump when using CMAC with dgst. The raw format is an encoding of a SubjectPublicKeyInfo structure, which can be found within a certificate; but openssl dgst cannot process a complete certificate in one go.. You must first extract the public key from the certificate: openssl x509 -pubkey -noout -in cert.pem > pubkey.pem * Active 3 years, 5 months ago. Demonstrates how to duplicate this OpenSSL command: openssl dgst -sha256 -sign private.pem -out sha256.sig in.dat The in.dat file can contain text or binary data of any type. enc To encrypt/decrypt using secret key algorithms. openssl dgst -sign key.pem -keyform PEM -sha256 -out data.zip.sign -binary data.zip. openssl dgst -sha256 -sign -out /tmp/sign.sha256 openssl base64 -in /tmp/sign.sha256 -out where is the file containing the private key, is the file to sign and is the file name for the digital signature in Base64 format.
