e2f7eb36d6 In PGP public key tests, encrypt the secret key with AES not CAST5,
so that the test passes with or without OpenSSL.  Marko Kreen

1abf76e82c "Annual" pgcrypto update from Marko Kreen:
Few cleanups and couple of new things:

 - add SHA2 algorithm to older OpenSSL
 - add BIGNUM math to have public-key cryptography work on non-OpenSSL
   build.
 - gen_random_bytes() function

The status of SHA2 algoritms and public-key encryption can now be
changed to 'always available.'

That makes pgcrypto functionally complete and unless there will be new
editions of AES, SHA2 or OpenPGP standards, there is no major changes
planned.

87688ddf87 The large one adds support for RSA keys and reorganizes
the pubkey functions a bit.  The actual RSA-specific code
there is tiny, most of the patch consists of reorg of the
pubkey code, as lots of it was written as elgamal-only.

---------------------------------------------------------------------------

The SHLIB section was copy-pasted from somewhere and contains
several unnecessary libs.  This cleans it up a bit.

 -lcrypt
   we don't use system crypt()

 -lssl, -lssleay32
   no SSL here

 -lz in win32 section
   already added on previous line

 -ldes
   The chance anybody has it is pretty low.
   And the chance pgcrypto works with it is even lower.

Also trim the win32 section.

---------------------------------------------------------------------------

It is already disabled in Makefile, remove code too.

---------------------------------------------------------------------------

I was bit hasty making the random exponent 'k' a prime.  Further researh
shows that Elgamal encryption has no specific needs in respect to k,
any random number is fine.

It is bit different for signing, there it needs to be 'relatively prime'
to p - 1,  that means GCD(k, p-1) == 1, which is also a lot lighter than
full primality.  As we don't do signing, this can be ignored.

This brings major speedup to Elgamal encryption.

---------------------------------------------------------------------------

o  pgp_mpi_free: Accept NULLs
o  pgp_mpi_cksum: result should be 16bit
o  Remove function name from error messages - to be similar to other
   SQL functions, and it does not match anyway the called function
o  remove couple junk lines

---------------------------------------------------------------------------

o  Support for RSA encryption
o  Big reorg to better separate generic and algorithm-specific code.
o  Regression tests for RSA.

---------------------------------------------------------------------------

o  Tom stuck a CVS id into file.  I doubt the usefulness of it,
   but if it needs to be in the file then rather at the end.
   Also tag it as comment for asciidoc.
o  Mention bytea vs. text difference
o  Couple clarifications

---------------------------------------------------------------------------

There is a choice whether to update it with pgp functions or
remove it.  I decided to remove it, updating is pointless.

I've tried to keep the core of pgcrypto relatively independent
from main PostgreSQL, to make it easy to use externally if needed,
and that is good.  Eg. that made development of PGP functions much
nicer.

But I have no plans to release it as generic library, so keeping such
doc
up-to-date is waste of time.  If anyone is interested in using it in
other products, he can probably bother to read the source too.

Commented source is another thing - I'll try to make another pass
over code to see if there is anything non-obvious that would need
more comments.

6a8eb1a7b6 pgcrypto update:
* test error handling
* add tests for des, 3des, cast5
* add some tests to blowfish, rijndael
* Makefile: ability to specify different tests for different crypto
  libraries, so we can skip des, 3des and cast5 for builtin.

e5cf1a8a26 SET autocommit no longer needed in /contrib because pg_regress.sh does
it automatically now on regression session startup.
