    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
