Hi All, I'm trying to decode a base64 encoded string. The problem I'm running in to is that BIO_read() always returns 0. BIO_should_retry() and BIO_should_read() also return 0 when BIO_read() returns 0. If the base64 encoded string is shortened, BIO_read returns the decoded information. I'm using OpenSSL 0.9.8g 19 Oct 2007 on Ubuntu 9.04.
Any suggestions on what I'm doing wrong?
