I've pushed scratch/tzz/gnus-cloud-aead with a proposed implementation
to use the native GnuTLS AEAD symmetric ciphers for gnus-cloud storage.
While this specifically is for IMAP articles, the implementation can
encrypt/decrypt any unibyte text data using AEAD ciphers.
Reasons to implement it this way:
* no dependency on external tools
* low risk: optional storage method for non-critical data
TODO:
* move the new code out to a library, either in core or in the GNU ELPA
* document, factor some things out
* add a checker function to read-passwd for min/max etc. requirements
It worked well in my testing. Comments and suggestions welcome.

Did you test this code with non-ASCII text? There are some tricky
shenanigans with multibyte text in the associated gnutls.c functions,
and you are using base64-encode-region, which will signal an error if
any non-ASCII characters are found in the region it is invoked on. So
I'd suggest to have that tested.
And then there are the TODOs, of course.
Thanks.
