Null cipher. For the configuration option in modern communication systems, see Null encryption. A null cipher, also known as concealment cipher, is an ancient form of encryption where the plaintext is mixed with a large amount of non-cipher material. Today it is regarded as a simple form of steganography, which can be used to hide ciphertext.

Which is an example of a null encryption algorithm?

Examples of this are the “eNull” cipher suite in OpenSSL and the “NULL Encryption Algorithm” in IPSec. “ciphers – SSL cipher display and cipher list tool”. RFC 2410 – The NULL Encryption Algorithm and Its Use With IPsec

What does it mean to switch off ciphering?

If it contains a valid value for an algorithm, then ciphering should be switched on using this algorithm. But if ciphering is already on, and it contains then no ciphering should be applied. Therefore, you could interpret that as “switch off ciphering”.

When do you need to use ciphering and integrity?

Ciphering is needed when you want that only authorized people can ACCESS TO SEE the data. Integrity is when authorized people can ACCESS TO MODIFY the data. As you can see, both ciphering and integrity need an authentication and authorization phase before.
