Re: Pgcrypto install (I've tried multiple ways)

I did read about the pgp functions but they are on another level right now.
I just want to be able to encrypt and decrypt data to a database
competently.  From there I'll learn about the more advanced functions.

bytea is for arbitrary byte strings, ie, non-textual data.  Typically
you'd store the output of encrypt() (which yields bytea) in the database
and then apply decrypt() to that.  Not sure what you're trying to do
above.

BTW, according to the pgcrypto man page, use of the PGP functions is
preferred over directly using encrypt/decrypt.
