Peter Eisentraut	814e1d9ff7	pgcrypto: Remove explicit hex encoding/decoding from tests ... This was from before the hex format was available in bytea. Now we can remove the extra explicit encoding/decoding calls and rely on the default output format.

Alvaro Herrera	188f359d39	pgcrypto: support changing S2K iteration count ... pgcrypto already supports key-stretching during symmetric encryption, including the salted-and-iterated method; but the number of iterations was not configurable. This commit implements a new s2k-count parameter to pgp_sym_encrypt() which permits selecting a larger number of iterations. Author: Jeff Janes	10 years ago
Peter Eisentraut	001e114b8d	Fix whitespace issues found by git diff --check, add gitattributes ... Set per file type attributes in .gitattributes to fine-tune whitespace checks. With the associated cleanups, the tree is now clean for git	12 years ago
Tom Lane	bcba09e27c	Ooops, missed that a couple of contrib modules have calls to byteacmp. ... Add bytea.h inclusions as needed. Some of the contrib regression tests need to be de-hexified, too. Per buildfarm.	16 years ago

Bruce Momjian	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. --------------------------------------------------------------------------- Marko Kreen	20 years ago
