ckolivas ae63349e3c We do need to seek to read the MD5 correctly on very small files so support seeking to end and then seek to the md5 start. 2011-03-17 11:53:29 +11:00
ckolivas 660243b8dc Pad out first block if less than CBC_LEN and encrypting or else encryption will fail. 2011-03-17 11:19:34 +11:00
