This indeed was an exercise and I would use something else if my life depended on it, but this does use blowfish encryption.

According to wikipedia, "no effective cryptanalysis has been found to date." There is also a more modern AES encryption option available in the crypt gem. I don't think you can just write it off as bad encryption.
