800xA Digital Signature

Ensure that critical aspects remain unmodified.

The system can be configured to require that certain aspects, such as a configuration aspect, a report, or a control application are signed by a user.

The digital signature incudes the identity of the signer, the date & time of the signing, and a cryptographic checksum of the signed aspect.

Later, the signature can be used to check if the aspect has been manipulated – if it has, the signature has been broken ad the “result” status will change to invalid.

User verification is performed by using the Windows user ID and password in combination with a selected reason for signature and an optional comment.
