Cipher, code, encrypt


Senior Member
Hi, everybody,

What's the difference between cipher, code, encrypt.
For example, what's the difference between ciphered document, coded document, and encrypted document?

I oftern hear code/decode in war films but I've never heard cipher/decipher or encrypt/decrypt. Why is code/decode often used in war films?

    Take them all as one word with the same meaning, Code = cipher = decrypt, but using in different situations:

    Code = General
    Cipher = In writing
    Encrypt = Computing

    And, the prefix de- is obvious; removing the code/cipher/encrypt...

    The differences are more complex, and cryptography is not only restricted to computing. In general writing, though, the above poster is correct that differentiation is not often noted.
