As Kris Jurka found out, pgcrypto does not work with
OpenSSL 0.9.6x. The DES functions use the older 'des_'API, but the newer 3DES functions use the 0.9.7x-only'DES_' API.I think I just used /usr/include/openssl/des.h for referencewhen implementing them, and had upgraded OpenSSL in themeantime.Following patch converts DES also to newer API and providescompatibility functions for OpenSSL < 0.9.7.I chose this route because:- openssl.c uses few DES functions.- compatibility for old 'des_' API is going away at some point of time from OpenSSL.- as seen from macros, new API is saner- Thus pgcrypto supports any OpenSSL version from 0.9.5 to 1.0Tested with OpenSSL 0.9.6c and 0.9.7e.Marko Kreen
