CryptoJS supports the following modes: 密码分组链模式(CBC)(the default):对于每个待加密的密码块在加密前会先与前一个密码块的密文异或然后再用加密器加密。第一个明文块与一个叫初始化向量的数据块异或。 密文反馈模式 (CFB): CFB能够将块密文(Block Cipher)转换为流密文(Stream Cipher) 计数器模式(CTR):...
The CFB (Cipher FeedBack) mode of operation allows the block encryptor to be used as a stream cipher. It also needs an IV. First, CFB will encrypt the IV, then it will xor with plaintext block to get ciphertext. Then we will encrypt the encryption result to xor the plaintext. Becaus...
The CFB shares two advantages over CBC mode with the stream cipher modes OFB and CTR (see further): the block cipher is only used in the encrypting direction and the message does not need to be padded to a multiple of the cipher block size (though CipherText stealing can also be used)...

with different functionality and properties. For example, some of these modes can be used to define a stream cipher. Furthermore, block ciphers are used as building blocks in other common cryptographic primitives such as hash functions (essential for public key cryptography), message authentication ...
Thus, block ciphers can be turned into byte-oriented stream ciphers by using an 8 bit mode such as CFB8 or OFB8. Modes such as Authenticated Encryption with Associated Data (AEAD) provide authenticity assurances for both confidential data and Additional Associated Data (AAD) that is not ...
