In case of AES-128, the blocksize is 128, the keysize is 128 and hence the IV is 128 bits. The best way to do this is by creating a random AES key and using it as IV. This random IV may be public as long as it is not reused in subsequent encryptions with the same key. edit: 2020-06-08 Note that after AES-CTR encryption the initial vector (IV) should be stored along with the ciphertext, because without it, the decryption will be impossible. The IV should be randomly generated for each AES encryption (not hard-coded) for higher security.

The IV of AES is always 128 bit regardless of the key length, meaning this leaves 32 bit (128 bit - 96 bit) for the counter which gives CTR (counter mode) its name. With a nonce of 96 bits, you can encrypt 2^32 blocks (a block is always 128 bit in size) without repeating the counter.

These will fail catastrophically on IV reuse. For all intents and purposes an attacker will be able to recover both plaintexts from two ciphertexts.

I plan to use AES-128-CTR with an IV of 0 and the SHA-256 of the plaintext as the key. IV values are required to produce different output with the same key, but I am explicitly avoiding that behaviour here.

// AES CTR is a stream cipher using the AES block cipher in counter mode. // This implementation works on both little and big endian architectures. // This is free and unencumbered software released into the public domain - November 2017 waterjuice.org 2019-04-03 · AES-CTR Encryption/Decryption. CTR mode has similar characteristics to OFB, but also allows a random access property during decryption. CTR mode is well suited to operate on a multi-processor machine where blocks can be encrypted in parallel. Furthermore, it does not suffer from the short-cycle problem that can affect OFB. Simple chosen-plaintext attack on AES-CTR given NONCE and IV re-use for multiple ciphertexts. Basically just a OTP chosen-plaintext attack implementation.

If the a key is reused with the same IV (or a numerically-close one), this will will produce duplicate values in the stream with which your plaintext is hashed. IV's are equal in size with of your block. In case of AES-128, the blocksize is 128, the keysize is 128 and hence the IV is 128 bits.
