You should probably store the key as a BLOB or convert it to a string using some algorithm like BASE64, store it in the db, retrieve it, and then convert it back yourself.

You could store it in a file using Crypt::RSA::Private and using a key to encrypt it (see the doc). If it is unencrypted in the MySQL db, it may still be vulnerable to discovery.
