fingerprint is null when importing a key on non english GPG version

[ValkA]

Can be temporarily fixed by adding environment variable LANG=en.

The fingerprint is null because of the following regex in gpg.js which assumes English output:
var keyRegex = /^gpg: key (.*?):/;

Well, ideally your server should be set in English. If for some reason, you need any other language set in your system, you can implement a custom import function. Basically:

• copy paste import function from source code: https://github.com/drudge/node-gpg/blob/master/lib/gpg.js#L248 to your target file
• Inside of that copy-pasted function, replace spawnGPG(keyStr, defaultArgs, args, function(importError, result) { with gpg.call(keyStr, defaultArgs, function(importError, result) {
• Change keyRegex to desired one that'll fix your issue
• Use your custom import function, instead of gpg.import

Another solution - simply fork the package and fix that keyRegex :D Use your fork instead of the package
