## About distributing Proof Information

In the following cases, you must present your Signature Proof Information to another user to have the Electronic Signature added to his / her Electronic Signature Case as a Trusted Electronic Signature:

- When another user specifies your My Electronic Signature as one of the Electronic Signatures that can open a protected document he / she creates

Make sure to distribute the Proof Information using secure means such as copying it to a floppy disk and handing it to another user, or attaching it to a mail message for which the receiver can verify its sender.
