Tom Lane	234a02b2a8	Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len). ... Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with VARSIZE and VARDATA, and as a consequence almost no code was using the longer names. Rename the length fields of struct varlena and various derived structures to catch anyplace that was accessing them directly; and clean up various places so caught. In itself this patch doesn't change any behavior at all, but it is necessary infrastructure if we hope to play any games with the representation of varlena headers.

Neil Conway	87a50169d2	Minor code cleanup for pgcrypto: for UDFs declared to be strict, checking ... for NULL-ness of function arguments is wasted code.	19 years ago
Bruce Momjian	436a2956d8	Re-run pgindent, fixing a problem where comment lines after a blank ... comment line where output as too long, and update typedefs for /lib directory. Also fix case where identifiers were used as variable names in the backend, but as typedefs in ecpg (favor the backend for indenting). Backpatch to 8.1.X.	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	20 years ago
