  -l                     Lists all UEFI variables.
  -l -sg                 Sorts variables by their GUIDs.
  -l -sn                 Sorts variables by their names.
  -G:"GUID"              Specifies the variable GUID.
  -N:"Name"              Specifies the variable name.
  -A:"xx"                Specifies the variable attribute.
  -hd                    Dumps the content of the variable(s) in Hex.
  -bd[[:]["filename"]]   Dumps the content of the variable(s) in Binary file.
  -b64[[:]["filename"]]  Dumps the content of the variable(s) in Base64.
  -I:"fname"             Imports from binary or base64 file (need GUID and NAME).
  -i:"fname"             Imports from binary or base64 file (using filename).
  -D                     Deletes the variable (DANGEROUS!)
  -WB64:"b64data"        Writes the variable data (creating the variable if needed).
  -WHEX:"hex string"     Writes the variable data (creating the variable if needed).
  -APPEND                Appends the data to the existing variable.
  -h/-H                  Show this help sheet.
  -m/-M                  Manual with examples.
  -z                     Donate (please donate more than $2 or PayPal will take it all)

1. you are not very clever and very bad at reverisng software.
2. the http request is just for statistics.
3. it has been obfucated only to make it more difficult to be used as a "weapon".
4. nobody cares if one paranoid does not use it. Hundreds of downloads prove otherwise.

This is malware.

This is malware.

NO, THIS IS NOT.
And this kind of comments is what you get when you offer something for free to morons.
