Without the key, it is nearly impossible for hackers to intercept and decode the message. This method is also called secret-key or private-key cryptography because only a single key is used during the process. There are two main types of symmetric key cryptography: Stream Cipher - A ...

Every single encryption algorithm makes use of a string of bits – widely known as the “key” – to execute the calculations.The longer the encryption key (the more bits), the more possible calculation patterns can be created, and the harder it will be to decrypt the ciphertext without a...
What is a cipher? A cipher (or cypher) is a pair of algorithms that create the encryption and the reversing decryption. The operation of a cipher is controlled both by the algorithm and in each instance by a “key.” The “key” is a secret parameter known only to the communicants for...

No, really, one of the motivations for several CAESAR entries was to design an authenticated encryption scheme, preferably based on a stream cipher, that is resistant to nonce reuse. (Reusing a nonce with AES-CTR, for example, destroys the confidentiality of your message to the degree a first...
How algorithms and keys are used to make a plaintext message unintelligible After the data is converted from plaintext to ciphertext, it can be decoded only through the use of the proper key. This key might be the same one used for encoding the data or a different one, depending on th...
