Re: [PATCH] _gpg: Use explicit UIDs for public / secret keys.



Daniel,

I would like you to tell me how can I solve better the `fpr` thing.

To tell you the truth, I have no idea what `fpr` means. I just know, by
comparing the output of `gpg --list-public-keys` with and without
`--with-colons`, that the hexadecimal number afterwards is the actual
key that needs to be used as an argument for these options. The way I
understand it, only if there is an email address / description coming
somewhere after the array element `fpr` (without another `fpr` in
between), then this field is the description.

Please tell me, how can this algorithm get better? I've had one idea in
mind: Perhaps we can perform a more strict pattern matchings test before
adding a uid for example?
