If I write an algorithm to encrypt a file, are their tools available to break the encryption?

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 of the encryption process (or intercepted 'keys'), meaning I'd have to build my own cracker for testing?
