482 * Major argument / variable rewrite. Introduced use of size_t
483 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100484 better unsigned / signed use. Renamed internal bigint types
485 t_int and t_dbl to t_uint and t_udbl in the process

514 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +0100515 before parsing a key or keyfile!
