What is a digitally signed file?
A digitally signed file is a document that has been electronically signed using a digital signature. This signature serves as a unique identifier that verifies the authenticity and integrity of the document.
Step 1: Install a PDF Reader
Firstly, it is essential to have a PDF reader installed on your device. A popular choice is Adobe Acrobat Reader, which is free to download and widely compatible across different operating systems.
Step 2: Locate the Digitally Signed File
Once you have a PDF reader, navigate to the folder or location where the digitally signed file is saved. Ensure that you have the necessary permissions to access the file.
Step 3: Double-Click to Open the File
To open the digitally signed file, simply double-click on it. The PDF reader will launch and load the document.
Step 4: Verify the Digital Signature
After opening the file, the PDF reader will display information about the digital signature. Look for indications that the signature is valid, such as a green checkmark or the phrase “Signature Valid.”
Step 5: Check the Signer’s Identity
It is crucial to verify the identity of the signer. The PDF reader will provide details about the signer, such as their name and organization. Ensure that this information aligns with your expectations.
Step 6: Validate the Document Integrity
Digital signatures not only authenticate the signer but also ensure that the document has not been tampered with since the signature was applied. Confirm that the PDF reader confirms the integrity of the document, indicating that no alterations have been made.
Step 7: Review the Document
Once you have verified the digital signature and document integrity, you can proceed to review the contents of the file. Read through the document to get the information you require.
Step 8: Save and Share (if required)
If you need to save or share the digitally signed file, use the options provided by the PDF reader. Remember to choose appropriate storage locations and reliable sharing methods to maintain the security and integrity of the document.
Opening a digitally signed file online may sound complicated, but by following these simple steps, you can effortlessly access and validate the authenticity of your important documents. Remember to use a reliable PDF reader, verify the digital signature, and ensure the document’s integrity before proceeding. Happy document handling!
