Кодировать двоичный файл как текст в Windows 2000+ с помощью встроенных инструментов

Да, есть на самом деле .

Из cmd.exe,

Чтобы закодировать файл: certutil -encode inputFileName encodedOutputFileName

Чтобы декодировать файл: certutil -decode encodedInputFileName decodedOutputFileName

Here's a JScript-based script I've written which can translate a binary file to its hexadecimal representation, and vice-versa. Save the code as HexEncoder.js, or whatever you want as long it has the .js extension.

// Original script written by paulkienitz, 20110301 // http://www.codeproject.com/Messages/3718403/a-shorter-and-quicker-way-modified.aspx // Check the parameters count if (WScript.Arguments.length < 3) { WScript.Quit(2); } // Ensure the action parameter is long enough if (WScript.Arguments(0).length < 2) { WScript.Quit(3); } // Detect invalid characters var action = WScript.Arguments(0).toUpperCase().charCodeAt(1); switch (action) { // 'D' or 'E' case 0x44: case 0x45: break; default: WScript.Quit(3); break; } var fso = new ActiveXObject("Scripting.FileSystemObject"); var source = WScript.Arguments(1).replace("\\", "\\\\"); // Check whether the source file actually exists if (!fso.FileExists(source)) { WScript.Quit(4); } var dest = WScript.Arguments(2).replace("\\", "\\\\"); // When we read a binary stream as ISO 8859-1 (Latin 1), we should get a // string where each charCodeAt value matches the byte from the stream. // Unfortunately Windows won't give you Latin 1 -- when you ask for it, // you get code page 1252, which has extra characters stuck in for byte // values from 128 to 159. These two strings allow us to translate between // the bogus Windows characters and the original byte values. var bogusWindows1252Chars = "\u20AC\u201A\u0192\u201E\u2026\u2020\u2021" + "\u02C6\u2030\u0160\u2039\u0152\u017D" + "\u2018\u2019\u201C\u201D\u2022\u2013\u2014" + "\u02DC\u2122\u0161\u203A\u0153\u017E\u0178"; // No translation is necessary for characters 0x81, 0x8D, 0x8F, 0x90, or 0x9D var correctLatin1Chars = "\u0080\u0082\u0083\u0084\u0085\u0086\u0087" + "\u0088\u0089\u008A\u008B\u008C\u008E" + "\u0091\u0092\u0093\u0094\u0095\u0096\u0097" + "\u0098\u0099\u009A\u009B\u009C\u009E\u009F"; if (action == 0x44) // D { decode(source, dest); } else if (action = 0x45) // E { encode(source, dest); } // This turns a string read as codepage 1252 into a boxed string with a // byteAt method. function binaryString(str) { // Always return an object with a .length var r = str ? new String(str) : new String(); r.byteAt = function(index) { var value = this.charCodeAt(index); // Translate character back to originating Windows-1252 byte value if (value > 0xff) { var p = bogusWindows1252Chars.indexOf(this.charAt(index)); value = correctLatin1Chars.charCodeAt(p); } // Convert the value to hexadecimal var hex = value.toString(16); return (hex.length == 2) ? hex : "0" + hex; }; return r; } // Does reverse translation from bytes back to Windows-1252 characters. function fromByte(hex) { var c = String.fromCharCode(parseInt(hex, 16)); var p = correctLatin1Chars.indexOf(c); return (p == -1) ? c : bogusWindows1252Chars.charAt(p); } function encode(source, dest) { var stream = new ActiveXObject("ADODB.Stream"); stream.Type = 2 // adTypeText stream.Charset = "iso-8859-1"; // actually Windows codepage 1252 stream.Open(); stream.LoadFromFile(source); var chunkSize = 4096; encodedFile = fso.OpenTextFile(dest, 2, true); // 2 = ForWriting while (!stream.EOS) { var s = binaryString(stream.ReadText(chunkSize)); var tempArray = new Array(); for (var i = 0; i < s.length; i++) { tempArray[i] = s.byteAt(i); } var hexString = tempArray.join(""); if (hexString.length > 0) { encodedFile.Write(hexString); } } encodedFile.Close(); stream.Close(); } function decode(source, dest) { var chunkSize = 8192; var encodedFile = fso.OpenTextFile(source, 1); // 1 = ForReading var decodedFile = fso.OpenTextFile(dest, 2, true); // 2 = ForWriting while (!encodedFile.AtEndOfStream) { var hexString = encodedFile.Read(chunkSize); var tempArray = new Array(); for (var i = 0; i < hexString.length; i += 2) { tempArray[i >> 1] = fromByte(hexString.substring(i, i + 2)); } var s = tempArray.join(""); if (s.length > 0) { decodedFile.Write(s); } } decodedFile.Close(); encodedFile.Close(); } 

Syntax

To encode a binary file:

cscript /nologo /e:jscript HexEncoder.js /e "binary file" "output file" 

To revert back:

cscript /nologo /e:jscript HexEncoder.js /d "encoded file" "binary file" 

Example usage

The following command will encode notepad.exe and save the output to the desktop:

cscript /nologo /e:jscript HexEncoder.js /e "%windir%\notepad.exe" "%userprofile%\Desktop\notepad.exe-hex.txt" 

Known limitations

• Encoded files are twice the size of the original ones.

• The script is best suited for small files, say under 1024 KiB.

  Eventually you could work around these limitations by using the script above to transfer some third party encoder.
