The new versions of Microsoft Office make it possible for us to digitally sign our documents. This will mean that the documents cannot be modified and in the event that they were modified, such changes would be related to another user.
This practice is not only used in situations where we need a lot of security but also also in situations where we need to know who has written this document. Hence, it is becoming easier to digitally sign Microsoft Office documents.
There are two types of digital signature, one that is invisible and another that adds a watermark with the owner's data. We are going to teach you how to make the first type of signature, as it is more practical and common among users who need to digitally sign a document. To do this, after writing the document, we have to go to the "Information" tab, within the "File" menu.
In Information we are going to Protect Document and in the drop-down menu that appears, we are going to the option Add a digital signature. After this, a dialog window will appear in which we will press the accept button and a window will appear to sign the document. We will have to add the reason or text that the digital signature will have. After adding the reason for the digital signature, click the sign button and Microsoft Word will lock the document.
To remove or remove the signature from the document, we have to repeat the same process. That is, we have to go to File -> Information and press the button «See signatures». A window will appear with the list of signatures that this document has. Now we click on the arrow next to the name of the signature that we want to remove and press the button «Remove signature». This will automatically remove the signature from the document, releasing it and allowing you to edit it.
The digital signature offered by Microsoft Office is not very strong as you can see, but sufficient for many users and for many situations Do not you think?
