The openssl docs note that: Hex signatures cannot be verified using openssl. file or files to digest. Nginx needed the Leaf's Private Key the Leaf's Certificate or a certificate chain. digitally sign the digest using the private key in "filename". Key length must conform to any restrictions of the MAC algorithm OpenSSL uses the DER encoding for any binary output (keys, certificates, signatures etc. To verify a signature with the openssl dgst utility, run the following command: openssl dgst -sha256 -verify pubkey.pem -signature example.sign example.txt. Contribute to openssl/openssl development by creating an account on GitHub. IF file.pem contains an RSA privatekey (in which case that name is misleading) the output is a "bare" RSA PKCS#1(v1.5) signature -- an N-bit number where N is the modulus size, rounded up if necessary which it rarely is because people generally use key sizes like 1024 and 2048, without any of the metadata normally used with a signature. signatures using message digests. I couldn't see how you created your privkey, but the way to go is through the ASN.1 structure, and then base64 it. For more information about the format of arg for example exactly 32 chars for gost-mac. verifies the signature using the public key in filename. If you need to sign and verify a file you can use the OpenSSL command line tool.

When verifying signatures, it only handles the RSA, DSA, or ECDSA signature itself, not the related data to identify the signer and algorithm used in formats such as x.509, CMS, and S/MIME. PTC MKS Toolkit for System Administrators The ASN1 structure for a privkey looks like this: The digest of choice for all new applications is SHA1.
