How do I execute a command with a new .exe in powershell

Question

I want to decrypt a file that is AES encryptet, with a script on powershell. To decrypt it I want to use a openSSL binary, that the script automatically downloads. When I execute the openssl.exe with start-Process -FilePath "$pwd\openssl\openssl.exe" a new cmd-window opens and I can enter my command to decrypt the file there. (which works I have tested it) So my question: Is there a way to execute the command openssl aes-256-cbc -d -a -in secrets.txt.enc -out secrets.txt.new with the.exe without having to manually input it into the new window?

Answer 1

Yes, try this:

& ".\openssl\openssl.exe" aes-256-cbc -d -a -in secrets.txt.enc -out secrets.txt.new

Answer 2

Using Start-Process , you can pass the parameters with -ArgumentList :

Start-Process -FilePath "$pwd\openssl\openssl.exe" -ArgumentList "aes-256-cbc -d -a -in secrets.txt.enc -out secrets.txt.new"
