It don't need to be secret. In your .env file, put. Despite the presence of the IV, stream ciphers are not entirely secure. The length of an encoded vector must be an exact multiple of the length of a single element (e.g., a 17-byte vector of uint16 would be illegal). However, because the IV is short, the same key stream is often reused, which allows hackers to perform statistical attacks to recover the plaintext and decrypt traffic. You must use the exact same IV during encryption and decryption (of the same message). How dry does a rock/metal vocal have to be during recording? Would Marx consider salary workers to be members of the proleteriat? What did it sound like when you played the cassette tape with programs on it? Can a county without an HOA or Covenants stop people from storing campers or building sheds? Each block has its own [deterministic] initialization vector. In algorithms for matrix multiplication (eg Strassen), why do we say n is equal to the number of rows and not the number of elements in both matrices? UINT16 = 8 A 16-bit unsigned integer data type. An initialization vector (IV) or starting variable (SV) is a block of bits that is used by several modes to randomize the encryption and hence to produce distinct ciphertexts even if the same plaintext is encrypted multiple times, without the need for a slower re-keying process. What you want is: = Buffer); // set random encryption key) // set random initialisation vector. Must be 16 bytes. This means that the data was encrypted CTR mode so you need to pay to!
