Instructions for exporting/importing (backup/restore) GPG keys

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...

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

If opkg runs out of space, it will not remove the files it was installing. Run this custom script in order recover the space by removing these files and the installed dependencies.
#!/bin/sh
#takes one argument/parameter: the name of the package which didn't install correctly and should be removed along with its dependencies
#do opkg update first
#example: ./opkgremovepartlyinstalledpackage.sh pulseaudio-daemon
#get list of all packages that would be installed along with package x
opkg update
PACKAGES=`opkg --force-space --noaction install $1 | grep http | cut -f 2 -d ' ' | sed 's/.$//'`
for i in $PACKAGES

测试平台:DigitalOcean VPS ubuntu14.04 x64, strongswan5.2.2

运行以下命令请使用root权限

一:安装strongswan

由于ubuntu软件仓库中strongswan版本较低,因此从官网源码编译安装

apt-get install build-essential     #编译环境
aptitude install libgmp10 libgmp3-dev libssl-dev pkg-config libpcsclite-dev libpam0g-dev     #编译所需要的软件

[Regarding Python 2 - in Python 3 just use normal strings that are always Unicode.] // quick example of encoding and decoding a international domain name in Python (from Unicode to Punycode or IDNA codecs and back). Pay attention to the Unicode versus byte strings
# INCORRECT! DON'T DO THIS!
>>> x = "www.alliancefrançaise.nu" # This is the problematic line. Forgot to make this a Unicode string.
>>> print x
www.alliancefrançaise.nu
>>> x.encode('punycode')
'www.Alliancefranaise.nu-h1a31e'
>>> x.encode('punycode').decode('punycode')
u'www.Alliancefran\xc3\xa7aise.nu'
