In our proprietary database, we are using the encryption methods provided by openSSL . May be we can have a look at those methods provided by openSSL for the use of encryption for builds under USE_SSL. Ignore it if you have already validated. >> 5.

What I felt was, if we store the passphrase in an environmental variable, a person who is having an access to the system can get the details and using that it may be possible to decrypt the data files.  - https://www.openssl.org/docs/manmaster/crypto/EVP_EncryptInit.html Regards, Hari Babu Fujitsu Australia -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
