All,
I want to know that is there a way to determine if a ciphertext is encrypted with TDES or RC2?

Thanks,
Carl

Both are block ciphers with a block size of 64 bits. Given just the encrypted data you will be hard pressed to determine the algorithm used to perform the encryption. Besides, what would you do with it if you knew?
 
Well, you're not going to decrypt it (you can try, but you will fail). So I guess you can't do much.
