can't get new crypt2() function to work

[kobylka]

Hello Darren!


Ok, we got the symbols, now try to link them like this:

1. If your executable is 32bit you must use the 32bit library:

# cc -v /tmp/encrypter.c -o /tmp/encrypter -L/usr/lib/hpux32 -lrwtool_v2

2. If 64bit:

# cc -v /tmp/encrypter.c -o /tmp/encrypter -L/usr/lib/hpux64 -lprocsm


In your compile command you mixed both libraries (one is 32bit and the other 64 bit). This is not allowed.

Furthermore note the flags:

-L is used to specify a library search path
-l is used to specify the shortened name of the library to link with


Kind regards,

Kobylka

Kobylka,

Thanks for continueing to look at this. I'm on a 64-bit Itanium so I tried the hpux64 library as you suggested. Still no luck. I tried the 32-bit command, but that didn't work either. ):

Hello Darren!

For 64 bit the 64bit data model flag must be included:

# cc +DD64 -v /tmp/encrypter.c -o /tmp/encrypter -L/usr/lib/hpux64 -lprocsm


It should work using just -L/usr/lib too.
In the case of 32 bit executable you can use +DD32 or not, by default the compiler generates 32 bit binaries.

Kind regards,

Kobylka

Hi!

When you tried earlier in this post to lookup the "crypt2" symbol using:

find / -name '*.sl' -exec nm {} \; -print | grep -i -e crypt2 -e '^/' | more

be sure to pick the correct libraries:

The nm gets executed first (showing the macthing symbols, if any) and THEN prints the name of the library (not before the symbols are displayed). Please make sure the libraries are the correct ones.


Kind regards,

Kobylka

Kobylka,

Still no luck. ):

Hi!

Hi!


ld: Unsatisfied symbol "crypt_2passwd_salt" in file encrypter.o
1 errors.

The symbol should be "crypt2_passwd_salt". Correct your code and compile again in 64 bit with 64 bit libpath:

# cc +DD64 /tmp/encrypter.c -o /tmp/encrypter -L/usr/lib/hpux64 -lsec

Kobylka,

Boy do Ifeel sheepish! That spelling mistake was the cause of the problem from the very beginning! Thank you very, very much for your assistance. If I could, I'd give you 15 points for sticking with this issue through so many iterations. For the benefit of future ITRC users, here's the final solution. Thanks again!

# cat /tmp/encrypter.c
#include

main()
{
char *username;
char *oldhash;
char *salt;
char *key;
char *hashstring;
username = "user1";
key = "mypass";
oldhash = "$6$"; /* "$6$" = SHA512, "aa" = 3DES */
salt = crypt2_passwd_salt(oldhash, username);
hashstring = crypt2(key, salt);
printf("username = %s\n", username);
printf("salt = %s\n", salt);
printf("key = %s\n", key);
printf("hashstring = %s\n", hashstring);
