Moreover, the IV must not be reused because doing so can reveal information about the common blocks shared by two messages, thus allowing a hacker to decrypt a subsequent message. Plagiarism flag and moderator tooling has launched to Stack Overflow! The initialization vector must be 128 bits (16 bytes.) Invalid private key. It consists of the concatenation of two pieces: a fixed nonce, set at initialization. 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. : Class.System.Crypto.encryptWithManagedIV: line 50, column 1.
