CREATE FUNCTION

  . Pass arrays natively instead of as text between plperl and postgres

(The other half is translating pg array arguments to perl arrays - that
will have to wait for 8.1).

Add --encoding to pg_dump.

The Problem:  Occassionally a DBA needs to dump a database to a new
encoding.   In instances where the current encoding, (or lack of an
encoding, like SQL_ASCII) is poorly supported on the target  database
server, it can be useful to dump into a particular  encoding.  But,
currently the only way to set the encoding of  a pg_dump file is to
change  client_encoding in postgresql.conf and restart postmaster.
This is more  than a little awkward for production systems.

As Kris Jurka found out, pgcrypto does not work with
OpenSSL 0.9.6x.  The DES functions use the older 'des_'
API, but the newer 3DES functions use the 0.9.7x-only
'DES_' API.

I think I just used /usr/include/openssl/des.h for reference
when implementing them, and had upgraded OpenSSL in the
meantime.

Following patch converts DES also to newer API and provides
compatibility functions for OpenSSL < 0.9.7.

I chose this route because:

- openssl.c uses few DES functions.
- compatibility for old 'des_' API is going away at some point
  of time from OpenSSL.
- as seen from macros, new API is saner
- Thus pgcrypto supports any OpenSSL version from 0.9.5 to 1.0

This patch addresses the problem mentioned in the "process crash

http://archives.postgresql.org/pgsql-bugs/2005-06/msg00105.php

In several places PL/Python was calling PyObject_Str() and then
PyString_AsString() without checking if the former had returned
NULL to indicate an error.  PyString_AsString() doesn't expect a
NULL argument, so passing one causes a segmentation fault.  This
patch adds checks for NULL and raises errors via PLy_elog(), which
prints details of the underlying Python exception.  The patch also
adds regression tests for these checks.  All tests pass on my
Solaris 9 box running HEAD and Python 2.4.1.

In one place the patch doesn't call PLy_elog() because that could
cause infinite recursion; see the comment I added.  I'm not sure
how to test that particular case or whether it's even possible to
get an error there: the value that the code should check is the
Python exception type, so I wonder if a NULL value "shouldn't
happen."  This patch converts NULL to "Unknown Exception" but I
wonder if an Assert() would be appropriate.

The patch is against HEAD but the same changes should be applied
to earlier versions because they have the same problem.  The patch
might not apply cleanly against earlier versions -- will the committer
take care of little differences or should I submit different versions

19 years agoMajor pgcrypto changes:
Bruce Momjian [Sun, 10 Jul 2005 03:57:55 +0000 (03:57 +0000)]
Major pgcrypto changes:

of password-based encryption from RFC2440 (OpenPGP).

The goal of this code is to be more featureful encryption solution
than current encrypt(), which only functionality is running cipher
over data.

Compared to encrypt(), pgp_encrypt() does following:

* It uses the equvialent of random Inital Vector to get cipher
  into random state before it processes user data
* Stores SHA-1 of the data into result so any modification
  will be detected.
* Remembers if data was text or binary - thus it can decrypt
  to/from text data.  This was a major nuisance for encrypt().
* Stores info about used algorithms with result, so user needs
  not remember them - more user friendly!
* Uses String2Key algorithms (similar to crypt()) with random salt
  to generate full-length binary key to be used for encrypting.
* Uses standard format for data - you can feed it to GnuPG, if needed.

Optional features (off by default):

* Can use separate session key - user data will be encrypted
  with totally random key, which will be encrypted with S2K
  generated key and attached to result.
* Data compression with zlib.
* Can convert between CRLF<->LF line-endings - to get fully
  RFC2440-compliant behaviour.  This is off by default as
  pgcrypto does not know the line-endings of user data.

Interface is simple:

    pgp_encrypt(data text, key text) returns bytea
    pgp_decrypt(data text, key text) returns text
    pgp_encrypt_bytea(data bytea, key text) returns bytea
    pgp_decrypt_bytea(data bytea, key text) returns bytea

To change parameters (cipher, compression, mdc):

    pgp_encrypt(data text, key text, parms text) returns bytea
    pgp_decrypt(data text, key text, parms text) returns text
    pgp_encrypt_bytea(data bytea, key text, parms text) returns bytea
    pgp_decrypt_bytea(data bytea, key text, parms text) returns bytea

Parameter names I lifted from gpg:

   pgp_encrypt('message', 'key', 'compress-algo=1,cipher-algo=aes256')

For text data, pgp_encrypt simply encrypts the PostgreSQL internal data.

This maps to RFC2440 data type 't' - 'extenally specified encoding'.
But this may cause problems if data is dumped and reloaded into database
which as different internal encoding.  My next goal is to implement data
type 'u' - which means data is in UTF-8 encoding by converting internal
encoding to UTF-8 and back.  And there wont be any compatibility
problems with current code, I think its ok to submit this without UTF-8
encoding by converting internal encoding to UTF-8 and back.  And there
wont be any compatibility problems with current code, I think its ok to
submit this without UTF-8 support.

Here is v4 of PGP encrypt.  This depends on previously sent
Fortuna-patch, as it uses the px_add_entropy function.

- New function: pgp_key_id() for finding key id's.
- Add SHA1 of user data and key into RNG pools.  We need to get
  randomness from somewhere, and it is in user best interests
  to contribute.
- Regenerate pgp-armor test for SQL_ASCII database.
- Cleanup the key handling so that the pubkey support is less
  hackish.
