I've created a C# program that encrypts and decrypts a file. The encryption method is DES. The program is exactly the same as in the following link, except that the part that removes the key from memory has been commented out:
My question is, after running the program and creating a memory dump, how do I identify the encryption key using winhex? All I can see are random bytes of data. Is just finding the variable name "sSecretKey" considered finding the key?
