AES-CTR ciphers implementation. Cipher functionality is accessed using traits from re-exported stream-cipher crate. This crate will select appropriate implementation at compile time depending on target architecture and enabled target features.
Simple chosen-plaintext attack on AES-CTR given NONCE and IV re-use for multiple ciphertexts. Basically just a OTP chosen-plaintext attack implementation.
Repeating the counter is bad, very bad. AES-GCM-SIV decrypts a ciphertext by using the authentication as a nonce for AES-CTR. The plaintext recovered is then used along with the associated data to validate the authentication tag. Both tags need to be compared (in constant-time) before releasing the plaintext to the application. For each block in CTR mode a new unpredictable keystream block is generated based on the initial vector (IV, sometimes called "nonce") + the current counter (01, 02, 03,) + the secret encryption key and the input block is merged by XOR with the current keystream block to produce the output block.
