Method Detail

fromString

public static KeyPairAlgorithm fromString(String algName)

Looks up a key pair generation algorithm from its name. The names are those specified in the JCA spec. For example, "RSA" and "DSA".

Throws: NoSuchAlgorithmException If the name of the algorithm is not recognized as a supported algorithm.

Returns the algorithm family for a given key pair generation algorithm. If a token supports a family and is writable, we can do keypair gen on the token even if it doesn't support the keypair gen algorithm. We do this by doing the keypair gen on the internal module and then moving the key out to the other token.
