rc4

原文：https://pkg.go.dev/crypto/rc4@go1.23.0

Package rc4 implements RC4 encryption, as defined in Bruce Schneier’s Applied Cryptography.

​ rc4 包实现 RC4 加密，如 Bruce Schneier 的应用密码术中所定义。

RC4 is cryptographically broken and should not be used for secure applications.

​ RC4 在密码学上已被攻破，不应将其用于安全应用程序。

类型

type Cipher

1
2
3

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

1

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。

(*Cipher) Reset <- DEPRECATED

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。

(*Cipher) XORKeyStream

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。

type KeySizeError

1

type KeySizeError int

(KeySizeError) Error

1

func (k KeySizeError) Error() string
