Identifying Encryption Patterns
Identifying Encryption Patterns
This is for the people who worked with decryption of files (mostly game related files).
I have a basic idea of how the process of decrypting an entire file goes, the only thing missing is how to identify the encryption pattern(s).
I understand it's mostly done by observing how user input changes the data? But even if so, even if I know that the value "somevalue" equates to "503241567" after encryption, there can be so many ways to achieve that result without it being the encryption that that specific program uses.
My question is: How can I identify a file's encryption?
Looking forward to your guys' response!

google for PEiD if you want to check a exe. For game files like libraries its easiest to dump the from the running application (for example in StarWarsBatllefront).
