gpg-agent setup

Need to setup gpg-agent first, on OSX I use keychain (it also does ssh-agent)

$ brew info keychain
keychain: stable 2.8.5
User-friendly front-end to ssh-agent(1)
https://www.funtoo.org/Keychain
/usr/local/Cellar/keychain/2.8.5 (7 files, 108.5KB) *

For a safe and fast Erlang SSL server, there's a few 
configuration values you might want by default:

    [{ciphers, CipherList},      % see below
     {honor_cipher_order, true}, % pick the server-defined order of ciphers
     {secure_renegotiate, true}, % prevent renegotiation hijacks
     {client_renegotiation, false}, % prevent clients DoSing w/ renegs
     {versions, ['tlsv1.2', 'tlsv1.1']}, % add tlsv1 if you must

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...
