Openssl offers two ways to verify a result: openssl dgst -sha256 -verify pubkey.pem -signature tmpfile.sig sha256.txt. The OpenSSL hash output format is a bit different from GnuPG, but numerically identical. Otherwise, you will get compilation error like as "undefined reference to `SHA1_Init'" etc. Linux, for instance, ha… rev 2021.1.5.38258, Se vota a favor de las mejores respuestas, y éstas suben a los primeros puestos. OpenSSL generate hash of the file. Could you design a fighter plane for a centaur? I am learning to do the hash of a file in C using OpenSSL but I always get the same hash. Hash algorithms take an arbitrary amount of data and convert it into a manageable fixed-length representation of that data, like a signature for the original data. 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.
