                                                   throws java.lang.IllegalArgumentException

Create an AlgorithmIdentifier for the passed in encryption algorithm.

Parameters:

encryptionOID - OID for the encryption algorithm

keySize - key size in bits (-1 if unknown)

random - SecureRandom to use for parameter generation.

Returns:

a full AlgorithmIdentifier including parameters

Throws:

java.lang.IllegalArgumentException - if encryptionOID cannot be matched
