Having an alternative implementation to GnuPG is a pretty important. Although many would argue against the use of PGP encryption for many use cases such as email, there are other use cases where PGP's ideas have no replacement.<p>For a specific example take signing git commits. Even fossil scm delegates this task to pgp. Personally keybase is the only project that may provide some form of alternative, but they do so by supporting pgp.<p>I definitely agree that PGP was and is no longer the correct tool for every use case as it sort out to be, but I find there are still pockets where PGP has no alternative. I'd be interested what HN's thoughts are on PGP for this specific use case and if there could be an alternative.
