12 Dec 2017 Most often the CTR mode is combined with the AES block cipher which acts on 128-bits blocks. In that setting, the birthday bound may appear 

AES-CTR encryption is the XOR of the key stream with the plaintext. AES-CTR decryption is the XOR of the key stream with the ciphertext. If the generated key stream is longer than the plaintext or ciphertext, the extra key stream bits are simply discarded.

AES-GCM-SIV synthesizes the internal IV. The Advanced Encryption Standard (AES), also known by its original name Rijndael (Dutch pronunciation: [ˈrɛindaːl]), is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. CTR mode doesn't need separate encrypt and decrypt method. Encryption key can be set once. OpenSSL's AES_ctr128_encrypt takes care of most of the work, so the code can be simplified. Also we really need vector test. The block ciphers are schemes for encryption or decryption where a block of plaintext is treated as a single block and is used to obtain a block of ciphertext with the same size.

The block ciphers are schemes for encryption or decryption where a block of plaintext is treated as a single block and is used to obtain a block of ciphertext with the same size. Today, AES (Advanced Encryption Standard) is one of the most used algorithms for block encryption. Counter mode uses the forward transformation for both encryption and decryption.
