  • VBS Hexadecimal Exchange or Encryption Implementation Code


    Design sketch: Codes are encapsulated into functions for easy invocation: Copy codeThe code is as follows: Key = www-enun-net”Do not use numbers Wscript.echo now & “, encryption:”MyData = ReadBin(“test.jpg”)EnData = Encoder(MyData)WriteBin “E_test.jpg”, EnDataWscript.echo now & “, encryption:” Wscript.echo now & “, decryption:”MyData = ReadBin(“E_test.jpg”)UnData = Uncoder(MyData)WriteBin “U_test.jpg”, UnDataWscript.echo now & “, decryption:” Function ReadBin(FileName) Dim Stream, […]
