func (*Cryptor) Decrypt

func (c *Cryptor) Decrypt(cryptoCode CryptoType, isOrderStream bool, src []byte, keys ...[]byte) ([]byte, error)

* ** Encrypt 解密方法 ** @param cryptoCode 加密算法 ** @param isOrderStream 是否是有序字节流,针对UDP数据流，数据报有可能乱序，所以如果不是有序的，chacha20每次都需要初始化 ** @param src 原始数据 ** @param keys 密钥，不同算法密钥长度不一样 ** return 解密后的数据 *

func (*Cryptor) Encrypt

func (c *Cryptor) Encrypt(cryptoCode CryptoType, isOrderStream bool, src []byte, keys ...[]byte) ([]byte, error)

* ** Encrypt 加密方法 ** @param cryptoCode 加密算法 ** @param isOrderStream 是否是有序字节流,针对UDP数据流，数据报有可能乱序，所以如果不是有序的，chacha20每次都需要初始化 ** @param src 原始数据 ** @param keys 密钥，不同算法密钥长度不一样 ** return 加密后的数据 *
