Is it better to use a smaller, more accurate measuring cylinder several times or a larger, less accurate one for the same volume? MessageDigest md = MessageDigest.getInstance("SHA-256"); byte[] digest = md.digest(message); Generate a digital signature You need to have a PrivateKey object containing the signing key, which you can generate at runtime, read from a file bundled with your app, or obtain from some other source depending on your needs. OpenSSL's genpkey utility supports let's you generate RSASSA-PSS keys (you have to set the aglorithm parameter to RSA-PSS) but if it supports RSAES-OAEP keys the documentation certainly makes no indication of that. Similarily can be tested the SHA256, SHA384 and SHA512, just by replacing SHA1 with these hashes in above commands. RSA OAEP; The second one can use different hashing functions to create a hash of encoding parameters and then verify the hash at decoding step. je cherche à créer un hachage avec sha256 en utilisant openssl et C++. Il y a quelques cas particuliers où BC est pas compatible avec le défaut de mise en œuvre de Soleil. The resulting pointer is owned by the library and should not be freed by the caller.
