Timestamp support for e-mail signing RRS feed

  • Question

  • Hi,

    Is it possible to implement a timestamping service when digitally signing e-mails?

    After reading about code-signing and document signing, where one uses timestamping service to extend the validity of the signature beyond the certificates lifetime, it seems natural to have that functionality in email signing as well.

    regards

  • Hi,

    For timestamp service to work, it demands the client application support. The following are some articles for your reference:

    Hope it helps.
