Are you looking for the following code from sql/password.c ?
void hash_password(ulong *result, const char *password)
{
register ulong nr=1345345333L, add=7, nr2=0x12345671L;
ulong tmp;
for (; *password ; password++)
{
if (*password == ' ' || *password == '\t')
continue; /* skipp space in password */
tmp= (ulong) (uchar) *password;
nr^= (((nr & 63)+add)*tmp)+ (nr << 8);
nr2+=(nr2 << 8) ^ nr;
add+=tmp;
}
result[0]=nr & (((ulong) 1L << 31) -1L); /* Don't use sign bit (str2int) */;
result[1]=nr2 & (((ulong) 1L << 31) -1L);
return;
}
void make_scrambled_password(char *to,const char *password)
{
ulong hash_res[2];
hash_password(hash_res,password);
sprintf(to,"%08lx%08lx",hash_res[0],hash_res[1]);
}
Hope this helps.
Fred.
