type Cipher struct {
	// contains filtered or unexported fields
}

A Cipher is an instance of RC4 using a particular key.

Cipher是使用特定密钥的 RC4 实例。

func NewCipher(key []byte) (*Cipher, error)

NewCipher creates and returns a new Cipher. The key argument should be the RC4 key, at least 1 byte and at most 256 bytes.

NewCipher 创建并返回一个新密码。key 参数应为 RC4 密钥，至少 1 个字节，最多 256 个字节。

1
func (c *Cipher) Reset()

Reset zeros the key data and makes the Cipher unusable.

Reset 将密钥数据清零，使密码不可用。

Deprecated: Reset can’t guarantee that the key will be entirely removed from the process’s memory.

已弃用：Reset 无法保证密钥将从进程的内存中完全删除。

1
func (c *Cipher) XORKeyStream(dst, src []byte)

XORKeyStream sets dst to the result of XORing src with the key stream. Dst and src must overlap entirely or not at all.

XORKeyStream 将 dst 设置为 src 与密钥流进行异或运算的结果。Dst 和 src 必须完全重叠或根本不重叠。
