The problem is that the keyserver network is abused as free and
permanent data storage. We can't do much about it without larger
changes on the search capabilities of the keyservers. For more
information see the archives of the sks-devel list starting in July.

Ok. I was not aware that HKPS should already have the highest quality.

hkps pool really should be the most responsive, and it already requires clustered only servers for a couple of weeks to try to increase the responsiveness. Experience has shown that any keyserver with less than 3 nodes in a cluster should not be used towards end-users. But do you have any more debugging output as to the problem at hand?

I have this use case: A card based encryption key is used as a subkey on one of my keys but also on another key of mine. The reason for this can be that I want to have separate keys (with different fingerprints) for two user ids but still use the same card for decryption. Sure it is possible to figure out that the user ids belong together but it is not obvious on first sight. Another use case is a role account with a shared subkey with only one administering the primary key.

Thanks for your analysis and the report. The good news is that we had this already reported and have fixed it.

gpg: keydb_search failed: Provided object is too short

So these are the results for gpg -K:

This was additionally reported as https://bugs.debian.org/909755 -- it would be great to get a clear statement from the GnuPG project about handling the curated keyring use case.

Thank you for your detailed report. Seems like something strange is broken on your system and our error handling does not properly cover that.

After several experiments with attachment flags to get the same behavior outlook does for unsigned mails I could not find a way to set both the content-id and cause the attachment not to be hidden.

The reason for this appears to be the "Content-ID", this is usually set for embedded attachments like images and not for attachments like PDF's.
This leads to the attachment being hidden, e.g. if you have embedded images you do not want them to show up in the list of attachments.

Turns out that that was not the problem.

I want to be able to create an ed448 key using gpg, use it to sign things.

Please write a proper feature requests. Two words are bit too brief. You should indicate for what you want ed448 support: gpg, gpgsm, libgcrypt etc.

Interaction will be something like this:

Priority is high, because Gnuk Token requires this feature for testing its implementation.

I ran gpgconf --kill gpg-agent and then the suggested command for i in {1..10}; do gpg -v --no-tty --verbose -o - encrypted.gpg 2>mylog.$i > /dev/null & done. (I was already running with --verbose, does -v add something else?)

In the interests of completeness I also tried it on a much larger file (1GB) which was both signed and encrypted. I also set the decryption to show the session key just to confirm it was decrypting since the plaintext was being sent to /dev/null.

I am unable to replicate this on OS X 10.9 Mavericks.

Running with -v would really be helpful.

This was a regression from 59e8a7ee3bcd16275091c9535626e49fc2a6c4af where a performance improvement to cache an object caused this problem.

Ah wait, I just remembered T4142. Maybe that is related. I'll try to reproduce that one first.

Again one of these issues I can't reproduce :-/
