How would I reverse engineer a cryptographic algorithm?

Question

I wrote an application that encrypts text in this way:

1. Get the input text

2. Reverse the text

3. Convert to hexadecimal

4. <

Answer 1

You would need a larger text base than that and some understanding that the crypt is coming from a particular language/domain. Then based on the frequency of words in that language/domain, one could potentially decipher certain attributes form the text.

Of course, good ciphers work around this. Only poorly implemented ciphers can be broken easily with this method.
