102 * New with 3.0: use part of the flags to denote exact type of RSA key,
103 * some of which are limited to specific signature and encryption schemes.
104 * These different types share the same RSA structure, but indicate the
105 * use of certain fields in that structure.
106 * Currently known are:
107 * RSA - this is the "normal" unlimited RSA structure (typenum 0)
108 * RSASSA-PSS - indicates that the PSS parameters are used.
109 * RSAES-OAEP - no specific field used for the moment, but OAEP padding
110 * is expected. (currently unused)
111 *
112 * 4 bits allow for 16 types
