So close, and yet so far... You have left out the critical (and most likely problematic) piece; the DB insertion. I will bet that if you try to decrypt immediately after you encrypt, it will work fine. The problem is that either your insert or select is munging up the data. I have not used blobs with perl/dbi, so I am not aware of specific issues. Look at http://www.james.rcpt.to/programs/mysql/blob/. Is this the way you are creating the insert?
