Due to such weaknesses, the WEP is no longer a popular encryption algorithm. One way is to transmit it along with the ciphertext. 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. Decryption Initialization Vector (Required for AES Decryption) The series of random bits created by a random bit generator, unique for every encryption operation, that you used to encrypt your input files.
