Definition

The signature algorithm is used to specify the cryptographic signature function to use when digitally signing the digest data. Typically, text to be signed goes through three steps: 1) canonicalization, 2) digest, and 3) signature. This property is used to specify the algorithm that should be used for step #3. A signature class typically specifies a default signature algorithm, so this property rarely needs to be used in practice when specifying digital signatures.
