The AES Symmetric-Key Cipher - Concepts. The Advanced Encryption Standard (AES) cipher, also known as "Rijndael" is a popular, secure, widely used symmetric key block cipher algorithm, used officially as recommended encryption technology standard in the United States. AES operates using block size of 128 bits and symmetric keys of length 128, 160, 192, 224 and 256 bits.

Provides a high-performance SIV encrypts the S2V output and the plaintext using AES-CTR, keyed with the encryption key (K2). SIV can support external AES-CTR ciphers implementation. Cipher functionality is accessed using traits from re-exported cipher crate.
AES-CTR has many properties that make it an attractive encryption algorithm for in high-speed networking. AES-CTR uses the AES block cipher to create a stream cipher. Data is encrypted and decrypted by XORing with the key stream produced by AES encrypting sequential counter block values. AES-CTR is easy to implement, and AES-CTR can be pipelined and parallelized. AES-CTR also supports key stream precomputation.

For more details on the AES standard, refer to the AES standard document. 3.1 AES Encryption The AES-128 encryption process involves 10 rounds of encryption along with an initial round for the 128 bit data encryption. AES comes in 128-bit, 192-bit, and 256-bit implementations, with AES 256 being the most secure. In this article, we’ll explain how AES 256 encryption works and how it can be used to protect your data. What Is AES 256-Bit Encryption? AES was developed in response to the needs of the U.S. government.

Since encryption is not enough (and integrity actually much better), we are also pondering which authentication algorithm to use. In your JS code, you're using the 32-character string d6F3231q7d19428743234@123nab@234 directly as the AES key, with each ASCII character directly mapped to a single key byte.

In the Java code, you're instead first hashing the same string with MD5, and then using the MD5 output as the AES key.

AES is a symmetric key encryption cipher, and it is generally regarded as the "gold standard” for encrypting data.. AES is NIST-certified and is used by the US government for protecting "secure” data, which has led to a more general adoption of AES as the standard symmetric key cipher of choice by just about everyone.
Encryption key can be set once. OpenSSL's AES_ctr128_encrypt takes care of most of the work, so the code can be simplified. To ensure security, the key in this mode need to be changed for every 2^(n/2) encryption blocks. CTR mode. At the CTR (Counter) mode of operation, shown in Fig. 5, as an input block to the encryptor (Encrypt), i.e. as an IV, the value of a counter (Counter, Counter + 1,…, Counter + N – 1) is used. It also is a stream encryptor.
