Implemented but not tested at all.

For completeness, that's https://gitlab.freedesktop.org/poppler/poppler/-/issues/1595. dkg obviously filed that but it may be useful for others finding themselves here.

Fixed in 1.56.

I updated the branch.

We also discussed emails that can't be decrypted. They are due to implementation details just currently skipped. They will also be so in the future as an implementation detail.

Also implemented for 2.2

I see no workaround.
The attachments in the original mail are not gone, yes.
But the mail can't be forwarded with them.

ok, changed the text in the description of the ticket accordingly, but put two more "team" back in.

Dialogtext (winzige Politur):

We decided to

We got new suggestions for this:

Especially when an LDAP is configured, keys should be automatically refreshed in short intervals (5 days? Configurable?) to notify users about revoked keys or signatures from a trusted key.
Keys that are close to their expiration dates should be prioritized.
Maybe users want to configure for what mail domains a lookup on a configured LDAP should be done.

I think it is save to say that we will not implement pgp/inline encryption with attachments

The problem here is that we don't have the sha-2 fingerprint in our SQL tables. Thus we would not only need to do a full table search but also parse the actual blob to compute the sha-2 fingerprint.

I have done testing using my QES certificate with all combinations of the two options.

Thanks for reporting/requesting.

Well, I will re-use this as a feature request to add this feature. Workaround is to list the key with --with-keygrip and backup the ~/.gnupg/private-keys-v1.d/<keygrip>.key files.

Looks good to me on gpg4win-5.0.0-beta357 @ win10 for the following migrations (as stated in the description):

• gpg4win 4.3.1 -> gpg4win 5.0
• gpg4win 4.4.1 -> gpg4win 5.0

Pushed the changes in {gniibe/synch-spawn} branch.
It consists of three commits:

• rGb8b8afc5cf6f: build: Require libgpg-error 1.56 or newer.
• rG15b8bc7495db: w32: Synchronous spawning gpg-agent/dirmngr/keyboxd.
• rG6bd6826aa6ff: common:w32: Care about the NUL device for start_new_service.

There is a new --keyserver-option update-before-send which is enabled by default.

Done for gpg4win 5 and backported for VSD 3.4 (provided that the gpg4win-4-branch will be used for VSD 3.4).

Deselect email and select again (email gets decrypted again) attachments are back.

Several releases since the last commit and no specific bug reports. We can close this task.

Add gpd5x tag to ensure testing with Gpg4win.

Fixed with new GPGRT_PROCESS_STDIO_NUL flag.

Pushed the changes:

• Inheriting HANDLEs has been not working accurately
  • Before the fix, all HANDLEs were inherited
  • Only specified HANDLEs are inherited by: rE0b01950237ab: w32:spawn: Fix inheriting HANDLEs.
• HANDLEs by w32_open_null were leaked
  • fixed by: rEf28bf71b86ba: w32:spawn: Fix resource leaks for HANDLEs by w32_open_null.

T7723 fix by rE311fb769d1dd: w32:spawn: New flag GPGRT_PROCESS_STDIO_NUL.

Before implementing this feature, it's better to fix T7723: gpgrt:w32: Fix for inheriting stdin/stdout/stderr with "NUL", and do some clean up.

If we will fix gpgconf using GPGRT_PROCESS_STDIO_NUL, we will need to fix gpg-connect-agent to see if it's NUL or not.

Here is an experimental change to support the feature.

I'm testing the following patch with experimental change of libgpg-error.

Can't you just use file descriptors everywhere and use _get_osfhandle once you need a HANDLE. That is what I am used to seeing in Windows code in Gnulib (although I do not touch it much).

Regarding 64bit handles https://learn.microsoft.com/en-us/windows/win32/winprog64/interprocess-communication
tells us:

This seems to be a good opportunity to replace paperkey with a new tool to take advantage of the smaller ECC keys which allow us to re-generate most stuff.

Ingo tested this and it worked.
