ROT47 Caesar cipher encoder/decoder C#
Posted by Mikhail Esteves under: C#; Tips .
Here you go, Dan!
private char Rot47(char chr) { if (chr == ' ') return ' '; int ascii = chr; ascii += 47; if (ascii > 126) ascii -= 94; if (ascii < 33) ascii += 94; return (char)ascii; }public string Rot47(string str) { string RetStr = ""; foreach (char c in str.ToCharArray()) RetStr += Rot47(c).ToString(); return RetStr; }
Examples? ;) Encode like:
string myRot47EncStr = Rot47("My string!");
Decode like:
string myRot47DecStr = Rot47("|J DEC:?8P");
