Cryptographic algorithms used by token keys.

Typically, the supported algorithm for a token key can be represented by a value of the SecKeyAlgorithm enumeration. However, tokens such as Smart Cards require that input data for operations take the format of a more specific algorithm. For example, a token may accept raw data to generate a cryptographic signature, but require that raw data to be formatted according to PKCS1 padding rules. To express such a requirement, a TKTokenKeyAlgorithm object defines a target algorithm and a set of other algorithms that were used. In the previous example, the target algorithm is kSecKeyAlgorithmRSASignatureRaw and the kSecKeyAlgorithmRSASignatureDigestPKCS1v15SHA1 algorithm is also reported as being used.
