DESCRIPTION
3+
4+
Here is a implementation of crypto hashes for PostgreSQL.
5+
It exports 2 functions to SQL level:
6+
7+
digest(data::text, hash_name::text)
8+
which returns hexadecimal coded hash over data by
9+
specified algorithm. eg
10+
11+
> select digest('blah', 'sha1');
12+
5bf1fd927dfb8679496a2e6cf00cbe50c1c87145
13+
14+
digest_exists(hash_name::text)::bool
15+
which reports if particular hash type exists.
16+
17+
If any of arguments are NULL they return NULL.
18+
19+
HASHES
20+
21+
For choosing library you must edit Makefile.
22+
23+
standalone (default):
24+
MD5, SHA1
25+
26+
(the code is from KAME project. Actually I hate code
27+
duplication, but I also want to quarantee that MD5 and
28+
SHA1 exist)
29+
30+
mhash (0.8.1):
31+
MD5, SHA1, CRC32, CRC32B, GOST, TIGER, RIPEMD160,
32+
HAVAL(256,224,192,160,128)
33+
34+
openssl:
35+
MD5, SHA1, RIPEMD160, MD2
36+
37+
kerberos5 (heimdal):
38+
MD5, SHA1
39+
40+
