Hi all,
I'm rewriting my OLD crypt (Thanks to Henrique) C_fonction to version 0
forms :
I have this C file compiled OK to a shared library:
/*
*
* Henrique Pantarotto (scanner@cepa.com.br)
* Funcao para encriptar senhas (Function to encrypt passwords)
* September 1999
*
* PS: Note that all crypted passwords are created with salt "HP" (my name
* initials..) You can change that, or if you know C, you can do in a way
* that it will pick two random characters (the way it should really be).
*
*/
#include <strings.h>
#include <unistd.h>
#include <postgres.h>
text *post_crypt(text *user)
{text *password;char * crypt();long now=time((long *) 0);int len;char salt[7]="PY", *crypted;/*strcpy(salt,l64a(now));
salt[3]='\0';*/crypted=crypt(VARDATA(user),salt);len=strlen(crypted);password= palloc((int32) 13 +
VARHDRSZ);VARATT_SIZEP(password)=(int32) VARHDRSZ + 13;memcpy(VARDATA(password),crypted,len);return password;
}
text *sql_crypt(text *user,text *salt)
{ text *password; char * crypt(), *crypted; int len; char s[3]; strncpy(s,VARDATA(salt),2); s[2]='\0';
crypted=crypt(VARDATA(user),s);len=strlen(crypted); password=palloc((int32) 13 + VARHDRSZ);
VARATT_SIZEP(password)=(int32)13 + VARHDRSZ; memcpy(VARDATA(password),crypted,len); return password;
}
/*
Compile using something like this:
gcc -I/home/postgres/postgresql-6.5.1/src/include -I/home/postgres/postgresql-6.5.1/src/backend -O2 -Wall
-Wmissing-prototypes-fpic -I/home/postgres/postgresql-6.5.1/src/include -c -o encrypt.o encrypt.c
gcc -shared -o encrypt.so encrypt.o
And last, you create the trigger in PostgreSQL using this:
create function encrypt(text)
returns text as '/usr/local/pgsql/lib/encrypt.so' language 'c';
If everything is okay, you'll probably have: select encrypt('secret') working
and showing:
encrypt
------------
HPK1Jt2NX21G.
(1 row)
*/
I have defined to SQL function:
CREATE FUNCTION post_crypt(text) RETURNS text AS 'xxxx/encrypt.so'
CREATE FUNCTION sql_cypt(text,text) RETURNS text AS 'xxxx/encrypt.so';
WHY on earth does
SELECT post_crypt('test'),sql_crypt('test','PY')
NOT GIVE the same result???
Please help,
This is most urgent (My customer can't use this function anymore); it
worked OK with 7.0.3!!
Regards,
