in pghackers list. Support for oldstyle internal functions is gone (no longer needed, since conversion is complete) and pg_language entry 'internal' now implies newstyle call convention. pg_language entry 'newC' is gone; both old and newstyle dynamically loaded C functions are now called language 'C'. A newstyle function must be identified by an associated info routine. See src/backend/utils/fmgr/README. |

DESCRIPTION Here is a implementation of crypto hashes for PostgreSQL. It exports 2 functions to SQL level: digest(data::text, hash_name::text) which returns hexadecimal coded hash over data by specified algorithm. eg > select digest('blah', 'sha1'); 5bf1fd927dfb8679496a2e6cf00cbe50c1c87145 digest_exists(hash_name::text)::bool which reports if particular hash type exists. If any of arguments are NULL they return NULL. HASHES For choosing library you must edit Makefile. standalone (default): MD5, SHA1 (the code is from KAME project. Actually I hate code duplication, but I also want to quarantee that MD5 and SHA1 exist) mhash (0.8.1): MD5, SHA1, CRC32, CRC32B, GOST, TIGER, RIPEMD160, HAVAL(256,224,192,160,128) openssl: MD5, SHA1, RIPEMD160, MD2 kerberos5 (heimdal): MD5, SHA1
