1. The thing I used this for wad to decode and encode BASE64 strings. .It has two annoying features here - for decode and encode it needsencode:The bad thing is that the base64 strings are stored in a variable and there's a limitations for it's size.But for a small strings it wokrs.2. Much more interesting.In the help it shows that there's an -decodehex switch.And I was surprised to find that there's also an undocumentes switch -encodehex . Here's an example structure of encoded file:Any way it works for creation of the famous beep.bat :

certutil - decode/encode BASE64/HEX strings.Print symbols by HEX code
