WebbSM4是一种分组密码算法，其分组长度为128位（即16字节，4字），密钥长度也为128位（即16字节，4字）。其加解密过程采用了32轮迭代机制（与DES、AES类似），每一轮需要一个轮密钥（与DES、AES类似）。 1.引入密码算法相关包 org.bouncycastle bcprov-jdk15on WebbYou can define your own formats in order to be compatible with other crypto implementations. A format is an object with two methods— stringify and parse—that converts between CipherParams objects and ciphertext strings. Here's how you might write a JSON formatter:
