Sender Signs - Digital Seal®

RPost Digital Seal^® protection is a form of digital signature for the sender. RPost Digital Seal protection lets the sender electronically sign their email so the receiver or future recipient can verify the integrity and authorship of that email. The sender is protected against hoaxes, misrepresentation or imposture.

The Digital Seal protection proves (as long as the Digital Seal mark is associated with that email) who sent the email and what the original content was that they sent. This works for all email systems and it continues to work even after the email is forwarded from person to person.

Common Question:

How is RPost’s Digital Seal^® different from a PKI Digital Signature?

The main differences between the RPost Digital Seal^® protection and the PKI Digital Signatures are the following.

With the RPost Digital Seal^® protection:

• Any future recipient (second, third+) can verify origin, authorship, and integrity, since Digitally Sealed email can be forwarded and maintains its verification functionality. PKI Digital Signatures are fragile - the first recipient can verify origin, but if that email is forwarded, the act of forwarding breaks the signature.
• Any recipient can regenerate the original email. With PKI Digital Signatures, one cannot regenerate the original email content.
• The Digital Seal^® service works for all email systems (web mail, PINE, Terminal, etc.). PKI Digital Signatures require the recipient to have a compatible email program.
• The Digital Seal service adds a seal, signature, time and date stamp to each page of any attached PDFs.

Universality:
The Digital Seal service requires no recipient software to verify validity. This means that Digital Seal marks can be received and verified on web mail systems where Digital Signatures cannot.

Robustness:
Documents that have Digital Seal protection can be forwarded to any recipient and the Digital Seal mark still remains valid and can be verified.

Durability:
The original content and attachments of the message can always be regenerated from the Digital Seal service. Neither the RPost system nor any other party stores any email.

Step 1: Compose a new Message and press the "Send Registered" button.

Step 2: When the Registered Email feature pop-up appears, select the sending feature "Sign with Digital Seal -- electronically sign and time stamp" and press "Send" on the pop-up. This will make the email go as a Registered Email message with the Digital Seal protection.
