Thread: public key functions for postgresql ?
I need to store some sensitive data and I want to use public keys so anyone can encrypt the data but can only be decrupted by certain users. Anyhow, are there any loadable modules that do public key encryption for Postgresql ? I'd like to access these functions in plpgsql. It's probably not that hard, just don't want to re-invent the wheel. I could probably do it from plperl since there are plenty of perl PK tools. Reccomendations ? G

Look in contrib/pgcrypto.

Did I miss somthing ? I suppose it would be a good point to start adding some new public key functions.
I think you are right --- there are no public key functions in there. Perhaps the easiest way would be to detect a public-key library and make functions in pg_crypto to call them if they exist. --------------------------------------------------------------------------- Gianni Mariani wrote: > Tom Lane wrote: > > >Gianni Mariani <gianni@mariani.ws> writes: > > > > > >>Anyhow, are there any loadable modules that do public key encryption for > >>Postgresql ?

You're right. Now that I think about it, there was some discussion to
the effect of we couldn't include any actual encryption (as distinct
from crypto hashes) for fear of problems with various benighted export
laws.

This package seems to be very good, it includes all kind of asymetric encryption/decryption functions, and data types to store keys into postgresql tables.
It still unfinished, but maybe it already incorporates the functionality your looking for.

Thanks, it does. How much is this being used ?
