I have 3 projects and want in all 3 projects the same encrypt and decrypt methods. it works to get the same encrypted output for c# and php. But in powershell I get a slight diffrent output. Can someone EDIT my powershell script so I get same output in all 3?
Hi, I have 3 projects and want in all 3 projects the same encrypt and decrypt methods. it works to get the same encrypted output for c# and php. But in powershell I get a slight diffrent output. Can someone EDIT my powershell script so I get same output in all 3?
