Thanks for the reply. The key is being returned from the database correctly, so I'm not sure if storing it as a BLOB or converting it will help. And I'm using AES_ENCRYPT in MySQL, so the key is being stored securely. But if I pass the string directly to the decryption function like I show in the example, it gives me this error:
Can't call method "check" without a package or object reference at /us
+r/local/lib/perl5/site_perl/5.6.2/Crypt/RSA.pm line 133.
My guess is that it needs to be stored in a hash (which I've tried) or I'm just missing something. If I can't get this to work I'll just go ahead and encrypt it like you suggested but I would prefer to store it in the database. Any suggestions?
