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
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	20 years ago

Bruce Momjian	ab56022864	Big thanks to Solar Designer who pointed out a bug in bcrypt salt generation code. He also urged using better random source and making possible to choose using bcrypt and xdes rounds more easily. So, here's patch: * For all salt generation, use Solar Designer's own code. This is mostly due fact that his code is more fit for get_random_bytes() style interface. * New function: gen_salt(type, rounds). This lets specify iteration count for algorithm. * random.c: px_get_random_bytes() function. Supported randomness soure: /dev/urandom, OpenSSL PRNG, libc random() Default: /dev/urandom. * Draft description of C API for pgcrypto functions. New files: API, crypt-gensalt.c, random.c Marko Kreen	24 years ago
Bruce Momjian	2518e27334	/contrib/pgcrypto: * remove support for encode() as it is in main tree now * remove krb5.c * new 'PX library' architecture * remove BSD license from my code to let the general PostgreSQL one to apply * md5, sha1: ANSIfy, use const where appropriate * various other formatting and clarity changes * hmac() * UNX-like crypt() - system or internal crypt Internal crypt: DES, Extended DES, MD5, Blowfish crypt-des.c, crypt-md5.c from FreeBSD crypt-blowfish.c from Solar Designer * gen_salt() for crypt() - Blowfish, MD5, DES, Extended DES * encrypt(), decrypt(), encrypt_iv(), decrypt_iv() * Cipher support in mhash.c, openssl.c * internal: Blowfish, Rijndael-128 ciphers * blf.[ch], rijndael.[ch] from OpenBSD * there will be generated file rijndael-tbl.inc.

Bruce Momjian	e586026d10	The KAME files md5.* and sha1.* have the following changelog entry: ---------------------------- revision 1.2 date: 2000/12/04 01:20:38; author: tgl; state: Exp; lines: +18 -18 Eliminate some of the more blatant platform-dependencies ... it builds here now, anyway ... ---------------------------- Which basically changes u_int_t -> uint_t, so now it does not compile neither under Debian 2.2 nor under NetBSD 1.5 which is platform independent<B8> all right. Also it replaces $KAME$ with $Id$ which is Bad Thing. PostgreSQL Id should be added as a separate line so the file history could be seen. So here is patch: * changes uint_t -> uint. I guess that was the original intention * adds uint64 type to include/c.h because its needed [somebody should check if I did it right] * adds back KAME Id, because KAME is the master repository * removes stupid c++ comments in pgcrypto.c * removes <sys/types.h> from the code, its not needed -- marko Marko Kreen	25 years ago
