Hi,

I used Tools > Encrypt Data to secure variables defined into appveyor.xml
The first question is:
    What encrypt/decrypt algorithm bebind that tool?
My guess is AppVeyor generated unique password used for encrypt/decrypt.
Like this https://github.com/appveyor/secure-file

Another question is:
From this guide https://www.appveyor.com/docs/how-to/secure-files/
What is format of file when encrypt the content with multi variable keys?
   Ex: secure-file -encrypt <filename.ext> -secret <keyphrase> -out [filename.ext.enc]

I want to decrypt KEY1, KEY2 value during the build process then pass it to python script to do api call to outside service.
[appveyor.xml]
environment:
  KEY1:
     secure: xxxx
  KEY2:
     secure: yyyy
on_success:
- python myscript.py --key1=${KEY1} --key2=${KEY2}

Regards,

   Secure strings feature is currently supported in [environment], [deploy] and [notifications] sections. But how do I run my python script include parameters?

   - python myscript.py --key1=${KEY1} --key2=${KEY2}

   Is this for an Ubuntu or Windows build?

   The worker build is Ubuntu.

   In that case, you should just be able to drop the curly braces. i.e.
   

   - python myscript.py --key1=$KEY1 --key2=$KEY2

   It’s awesome.

   You mean that I don’t need to do decrypt before use secured variable.

   secure-file -decrypt file.enc

   Thank you very much for your support.
   The problem was solved.

   There are many ways to access environment from worker build.
   %var%
   $var
   ${var}
