I will track my progress and ask questions in this post. Here are some of my questions(Tried but not get the answer :( ) 1) How can I debug the JtR. I add -g to CFLAGS in Makefile. But gdb still can not find the symbols 2) I read the code in DES_fmt.c, it seems that it is a DES-Based algorithm. Now I do not clear about how the salt is obtained. The only available information I found about salt on DES is old unix /etc/passwd. They add 2 characters at the front of the encrypted password. However, the DES_raw_get_salt is more complex. Is there any document about this? I think I will implement original DES algorithm first. Does that okay? Thanks! Dongdong Li Content of type "text/html" skipped
