Software tools to automatically decrypt a file, whose encryption algorithm (and/or encryption keys) isn't known?
I have an idea for encryption that I could program fairly easily to encrypt some local text file. Given that my approach is novel, and does not use any of the industry standard encryption techniques, would I be able to test the strength of my encryption using 'cracker' apps or suchlike? Or do all those tools rely on advanced knowledge ...

OTP/XOR Cracking two ciphertexts that have the same key
How can I crack two ciphertexts that have used the same key twice? For example, plaintext1 uses the key "abcdefg", and plaintext2 uses the key "abcdefg". I know that ciphertext2 ^ ciphertext1 is equal to plaintext1 ^ plaintext2. And the method to crack plaintext1 ^ plaintext2 is the same method to crack a "book cipher" (also sometimes c...
