pemcracker – Tool For Cracking PEM Files

pemcracker is a tool for cracking PEM files that are encrypted and have a password. The purpose is to attempt to recover the password for encrypted PEM files while utilising all the CPU cores.

pemcracker - Tool For Cracking PEM Files

Inspired by Robert Graham’s pemcrack, it still uses high-level OpenSSL calls in order to guess the password. As an optimisation, instead of continually checking against the PEM on disk, it is loaded into memory in each thread.




Usage


bwall@ragnarok:~$ ./pemcracker

Password is komodia for test.pem
If you are looking for the fastest possible method of brute forcing PEM files, you may wish to try out John the Ripper. Its little known ssh2john allows for converting PEM files to a format that can be fed into ./john.
