How to securely store signature file
I am using TPM to to encrypt and sign my data. But since I am not security expert, I need to come to you guys :D
I am developing this app to verify file content. I already has this part sorted out with TPM. But now comes the tricky part. I have multiple people using this pc but only I have root access. How to store signature in file that only my app/me can access it? The file has to be on same pc as my app, this is pure offline.
So is there any better/cleaner solution than just altering rights to folder/file with chmod command? I don't know the best practices with storing signature files.
