We are using lately many digitally signed and/or encrypted Emails. KMail with gpg is doing great job in providing this. But there is missing a very important functionality in kMail. Most of users would like to have such signed or/and encrypted E-mails printed on paper. But after the printing of such E-mails, on the paper are missing any evidences that the printed E-mail is signed or/and encrypted by certain person and if the message signature is valid and if the key is trusted. This possibility is urgently needed in many cases of the real life and is creating a lot of troubles when encrypted or/and signed messages need to be printed. In such messages there is a hidden part caleld Details. If the user will click on the link 'Show Details' in the top of such messages he/she can see some info like following: "Message was signed by user@domain.net (Key ID: 0x5D5F095FF339EF76). The signature is valid and the key is fully trusted." or "Message was encrypted by user@domain.net (Key ID: 0x5D5F095FF339EF76). The signature is valid and the key is fully trusted." or "Message was signed and encrypted by user@domain.net (Key ID: 0x5D5F095FF339EF76). The signature is valid and the key is fully trusted." Please provide a option in the UI where users could choose if this details will be printed on top of the message text or not. Then when needed users will have the chance to print such messages with visible evidences about the signature or/and encryption status of the printed documents. Hopefully this will be easy to realize and can be made available very soon.
Indeed it can be useful. I will work on it soon.
Now we can print signature details (in future 5.10)
