This software was built from source available at https://github.com/oracle/solaris-userland. The digest functions also generate and verify digital signatures using message digests. Names and values of these options are algorithm-specific. Where -sha256 is the signature algorithm, -verify pubkey.pem means to verify the signature with the given public key, example.sign is the signature file, and example.txt is the file that was signed. Instead, use "xxd -r" The FIPS-related options were removed in OpenSSL 1.1.0. OpenSSL.

[-out filename] SAS supports the following types of OpenSSL hash signing services: RSAUtl. This engine is not used as source for digest algorithms, unless it is also specified in the configuration file. for example exactly 32 chars for gost-mac. When signing a file, dgst will automatically determine the algorithm (RSA, ECC, etc) to use for signing based on the private key's ASN.1 info. 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. SHA256 Hash. Raw hash as byte array is produced with the OpenSslDigest.Hash method. PTC MKS Toolkit for Enterprise Developers The signing and verify options should only be used if a single file is verifies the signature using the public key in filename.
