Only AES Counter mode (AES-CTR) is discussed in this specification. AES-CTR requires the encryptor to generate a unique per-packet value, and communicate this value to the decryptor. This specification calls this per-packet value an initialization vector (IV). The same IV … I am trying to implement AES CTR encryption mode with HMAC authentication for messages. It's encrypting and decrypting fine as long as the key length is 64 bytes, since AES key and HMAC key are being derived from this key.

In addition, ecb does not require any IV, while CTR requires a nonce.

The IV should be randomly generated for each AES encryption (not hard-coded) for higher security.

How this works precisely depends on the mode.

I am sure you have heard of AES encryption, but what exactly is AES CTR? AES CTR. CTR is a counter mode for AES encryption. It is also known as ICM and SIC. In AES encryption you have what is called an Initializing Vector, or IV for short.
