Encryption / Decryption via PGCrypto - Mailing list pgsql-admin

Hi Experts,

We are implementing the pgcrypto in our database to encrypt and decrypt the Column data. for testing purpose we have generate the PGP public / private key and use those when we read and write data.

How can we secure the key, if we keep the key outside how can we use that into query. 

Thanks for your help.
