131 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakker69e095c2011-12-10 21:55:01 +0000132 encountering a parse-error. Beware that the meaning of return values has
133 changed!

179 * Major argument / variable rewrite. Introduced use of size_t
180 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +0000181 better unsigned / signed use. Renamed internal bigint types
182 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000183 * mpi_init() and mpi_free() now only accept a single MPI

211 does not zeroize memory in advance anymore. Use rsa_init()
212 before parsing a key or keyfile!
