(start): Invalid value: Only valid value is 0: -16" Do you think this may be related to this package or is it something related locally to my project? For CFB mode, the IV must never be reused for different messages under the same key; for CBC mode, the IV must never be reused for different messages under the same key, and must be unpredictable in advance by an attacker. If the plaintext is 20 bytes in length, the first 16 bytes will form a block, and the remaining 4 bytes will be 12 bytes short of the 16 byte block size.

I use this as actual key, which is 16 char length. Specifically, during encryption, an IV prevents a sequence of plaintext that's identical to a previous plaintext sequence from producing the same ciphertext. Now Cut and paste all code from above into a js file eg file.js. When not the default 12 bytes (96 bits) sets the IV length using EVP_CIPHER_CTX_ctrl with type EVP_CTRL_GCM_SET_IVLEN In most cases, the length is comparable to the length of the encryption key or block of the cipher being used. In the Electronic Code Book (ECB) mode, which is a simple mode of operation with block ciphers, the same plaintext is always encrypted with the key into identical ciphertext.
