Function yaca::simple_calculate_signature

pub fn simple_calculate_signature(
    algo: &DigestAlgorithm, 
    prv_key: &Key, 
    message: &[u8]
) -> Result<Vec<u8>>

Creates a signature using asymmetric private key

• algo is a digest algorithm that will be used.
• prv_key is a private key that will be used, algorithm is deduced based on key type, supported key types:
  • KeyType::RsaPrivate,
  • KeyType::DsaPrivate,
  • KeyType::EcPrivate.
• message is message to be signed, it can be empty.
• The function returns a message signature.
• For DigestAlgorithm::Sha384 and DigestAlgorithm::Sha512 the RSA key size must be bigger than 512 bits.
• Using DigestAlgorithm::Md5 algorithm for DSA and ECDSA operations is prohibited.
