AES算法模块进行加密解密的代码片段

在此大家将采纳到PyCrypto模块,能够访问.
PyCrypto模块的成效是可怜庞大的,此处仅起一得之见的效应,感兴趣的爱人能够加强至其官网,当中有众多算法的例证。“`python

from Crypto.Cipher import AES

encryptor = AES.new(key, AES_MODE, IV)

encoding:utf-8

“”” 示例代码 “”” from Crypto.Cipher import AES key = ‘012345678九abcdef’
mode = AES.MODE_CBC encryptor = AES.new(key, mode) text = ‘j’ * 64 +
‘i’ * 128 ciphertext = encryptor.encrypt(text)

“”” 上例中的key是拾陆位, 还是可以是二4 或 3贰 位长度, 其对应为 AES-12捌,
AES-196 和 AES-25陆. 解密则能够用于下代码举办: “””

* AES, advanced Encryption Standard, it is very fast and secure, it’s
the ‘de facto’ (in effect/in fact) standard of symmetric encription; it
has a fixed block size of 16 bytes, its keys can be 128, 192, or 256
bits long.

decryptor = AES.new(key, mode)

* key, a byte string, the secret key to use in the symmetric cipher, it
must be 16(AES-128),24(AES-192), or 32(AES-256) bytes long.

plain = decryptor.decrypt(ciphertext)

“`

* MODE_constant: the chaining mode to use for encryption or
decryption.
