ROT13是
种简单
加密方式
主要是把26个英文字母前13个和后13个对调起到定英文文字加密保护作用
今天我们来看下在C#中使用ROT13加密解密实现我们就用个例子来为大家解答下把www. 虽然加密方式简单
但是Windows注册表里面都使用了ROT13加密可见其使用还是比较多 public
ROT13Encode(InputText) {
i; charCurrentCharacter;
CurrentCharacterCode; EncodedText=\"\"; //Iteratethroughthelengthoftheinputparameter
for(i=0;i<InputText.Length;i
) {
//Convertthecurrentcharactertoachar
CurrentCharacter=
.Convert.ToChar(InputText.Sub(i,1)); //Getthecharactercodeofthecurrentcharacter
CurrentCharacterCode=(
)CurrentCharacter; //Mod
ythecharactercodeofthecharacter,-this //sothat\"a\"becomes\"n\",\"z\"becomes\"m\",\"N\"becomes\"Y\"andsoon
(CurrentCharacterCode>=97&&CurrentCharacterCode<=109) {
CurrentCharacterCode=CurrentCharacterCode+13; [Page]
}
(CurrentCharacterCode>=110&&CurrentCharacterCode<=122) {
CurrentCharacterCode=CurrentCharacterCode-13;
}
(CurrentCharacterCode>=65&&CurrentCharacterCode<=77) {
CurrentCharacterCode=CurrentCharacterCode+13;
}
(CurrentCharacterCode>=78&&CurrentCharacterCode<=90) {
CurrentCharacterCode=CurrentCharacterCode-13;
}
//Addthecurrentcharactertothe
tobe
ed
EncodedText=EncodedText+(char)CurrentCharacterCode;
}
EncodedText; } [Page]
加密和解密
思路方法都样把
串传入思路方法返回得到串就是要加密和解密串了
