sStoring temporary sensitive data in memory (Windows)-CodePudding

I am building an automated workflow (using Saltstack) that delivers an encrypted password to a system that needs to be joined to a domain like this:

netdom join %computername% /domain:domain.com /UserD:user /PasswordD:passwrd

The encrypted password can be decrypted and fed into above line using another script. The difficulty is with the storage of this temporary encrypted password. So far, I can only think of two ways of doing this, neither of which is desirable:

RAMDISK - no built-in way to create one so there is a reliance on third party, no good
Environmental variables - persistent variables live in registry aka on disk so still no good

Any suggestions?

CodePudding user response：

It sounds like this password should be stored in an encrypted pillar.

#!yaml|gpg

net_password: |

join domain:
  cmd.run:
    - name: netdom join %computername% '/PasswordD:{{ pillar["net_password"] }}' /domain:domain.com /UserD:user

If you already have it set up in e.g. a Vault instance, you can use sdb to access it instead.
