1140 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001141 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001142 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().

1165 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001166 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +00001167
