Bruce Momjian	99058cfc63	Remove tabs after spaces in C comments This was not changed in HEAD, but will be done later as part of a pgindent run. Future pgindent runs will also do this. Report by Tom Lane Backpatch through all supported branches, but not HEAD	12 years ago
Bruce Momjian	df2e62603e	pgcrypto: fix memset() calls that might be optimized away Specifically, on-stack memset() might be removed, so: * Replace memset() with px_memset() * Add px_memset to copy_crlf() * Add px_memset to pgp-s2k.c Patch by Marko Kreen Report by PVS-Studio Backpatch through 8.4.	12 years ago
Heikki Linnakangas	4a75c7f9f1	If pk is NULL, the backend would segfault when accessing ->algo and the following NULL check was never reached. This problem was found by Coccinelle (null_ref.cocci from coccicheck). Marti Raudsepp	15 years ago
Bruce Momjian	d747140279	8.4 pgindent run, with new combined Linux/FreeBSD/MinGW typedef list provided by Andrew.	17 years ago
Bruce Momjian	1dc3498251	Standard pgindent run for 8.1.	20 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	21 years ago
Tom Lane	e997758cb6	More pgcrypto fixes: avoid bogus alignment assumptions in sha2, be more wary about having a value for BYTE_ORDER, clean up randomly- chosen ways of including Postgres core headers. Marko Kreen and Tom Lane	21 years ago
Bruce Momjian	e94dd6ab91	Add missing pgcrypto files from previous commit.	21 years ago
