Validating a signed file

The server provides a tool, validate-file-signature, that checks if a file has not been tampered with in any way.

Steps

  • Run the validate-file-signature tool to check if a signed file has been tampered with.

    Example:

    For this example, assume that the sign-log property was enabled for the File-Based Audit Log Publisher.

    $ bin/validate-file-signature --file logs/audit

    Result:

    All signature information in file 'logs/audit' is valid

    If any validations errors occur, you will see a message similar to the one as follows.

    One or more signature validation errors were encountered
while validating the contents of file 'logs/audit':
* The end of the input stream was encountered without
  encountering the end of an active signature block.
  The contents of this signed block cannot be trusted
  because the signature cannot be verified
