Problem is the hashing functions are not good for
password storage.

A general question: what is the status on patch acceptance
now, after 7.1 is successfully released?  I did not
want to fuzz around with new code when 7.1 was in freeze,
but what is the status now?

Specifically - pgcrypto current state:

In the pgsql/contrib:

* digest() / encode() - stable.

In my pgcrypto separate release:

* digest() / encode() / hmac() - stable.
  I have changed the internal interfaces compared to main CVS.

* crypt() / gen_salt() - stable.  DES/MD5/Blowfish crypt()
  (Blowfish is unreleased).  Code seems to be working quite

* encrypt() / decrypt() - unstable.  Not in the 'buggy'-sense,
  but the 0.3 encrypt() is unsatisfactory for long-term storage
  and security and compatibility.  Also their spec is confusing
  to users.  In the next release they will be renamed
  raw_encrypt() / raw_decrypt() as they really are interfaces
  to raw ciphers.  I keep them coz they are good for testing
  pgcrypto code ;) and also they are ok for crypting short

* future: encrypt() / decrypt() will be minimal implementation
  of OpenPGP standard (RFC2440). "Symmetrically Encrypted Data"
  with passwords.  (Is it too big? - The crypted data needs some
  structure and I dont think inventing some own format is good.)

Now for this OpenPGP stuff I dont have ATM not even
alpha-quality code.  So full release takes some time.
But hmac() and crypt() code is quite ok and there is no point
on me sitting on it alone.

So I would like to submit the mostly ready parts to main
tree.  When is the right time for it?
