When Redmine sends e-mails due to ticket updates the emails may contain sensitive information.

Thus it would be great if the user could upload his S/MIME certificate to redmine (next to where he enters his e-mail address)

All mails sent to the user will then be encrypted.

Instead of SMIME other encryptions standards could be used but my favorite one is SMIME

  • Subject changed from Encrypt emails with SMIME to Encrypt email notifications and accept encrypted incoming mail
  • Assignee set to Jan from Planio

Our colleague Jens here at Planio has something in the works using PGP/MIME which is IMHO a much better option than S/MIME, especially for an open source project like Redmine.

I will submit it here for discussion once it's ready. It is based on his open source Mail::Gpg gem. For the interested, there's a lengthy blog article about it.

Any update on this feature? We would love to have SMIME enabled on at least email notifications. Incoming email SMIME processing can be handled later.
