It maybe in the That is not true. The command line interface has been stable for the last 19 years. We only removed a left over PGP-2 backward compatibility in 2.1 (-kvv). I doubt that this has even been noticed. >> Unfortunately, gpgme does not solve the interoperability problems >> between gpg (1, classic, stable maint mode) or gpg2.0 (stable) and >> gpg2.1 (modern) key stores, and gpg2.2 (modern, stable) is not released >> yet. It actually does. For the tasks git uses gpg you should not notice a difference in gpgme between any of these versions. BTW, 2.1 was realeased more than 2 years ago and 2.0 will reach EOL in 9 months. > That is right, I also believe gpgme does not solve all interoperability > problems. I guess it solves some, but I would do more research to come up The main arguments pro GPGME are - There is generic stable API and ABI which did not changes since 0.4.1 (2003-06-06) when we decided to redesign the API. - Iff verification of signatures needs a speedup we can do this inside GPGME and GnuPG without the GPGME user noticing that. Technically we will then run gpg as co-process controlled by GPGME; for gpgsm (S/MIME) this is already done but there has not yet been a need to do this also for gpg. Git could be the trigger to implement that. - The GPGME API would allow to provide a rich and stable output with the pretty print format. AFAICS the current %G* format characters are a bit limited and require that scripts need to look at the key for further information. > The key store migration is mainly an orthogonal issue and the problems will > happen with or without using gpgme. As GnuPG 2.2 is under way, it makes sense Please note that 2.2 is more of a marketing term than a change. 2.1 is already in use and will be the standard gpg version in several distros, including Debian. Interoperability with 1.4 is a bit cumbersome if you often add new keys. However, "gpg --export | gpg1 --import" is not too complicated. Be aware that ECC keys will be used more and more and they are not supported by gpg1. Further we are currently defining a v5 key format to be prepared for weaknesses in the SHA-1 based fingerprint. It is very unlikely that a v6 key format will be added to gpg1. Salam-Shalom, Werner -- Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
