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
The PostgreSQL contrib tree --------------------------- This subtree contains porting tools, analysis utilities, and plug-in features that are not part of the core PostgreSQL system, mainly because they address a limited audience or are too experimental to be part of the main source tree. This does not preclude their usefulness. Each subdirectory contains a README file with information about the module. Most items can be built with `gmake all' and installed with `gmake install' in the usual fashion, after you have run the `configure' script in the top-level directory. Some directories supply new user-defined functions, operators, or types. In these cases, after you have installed the files you need to register the new entities in the database system by running the commands in the supplied .sql file. For example, $ psql -d dbname -f module.sql See the PostgreSQL documentation for more information about this procedure.
