nodiscc 91a21c2729 **General rewording, proof-reading, deduplication, shortening, reordering, simplification, cleanup/formatting/standardization**
- standardize page names, rework documentation structure, update TOC
- use same example paths everywhere
- level 1 titles on all pages
- fix broken links
- .md suffix on all page links (works both from readthedocs and github repository views)

**Server:**

A full and concise installation guide with examples is a frequent request. The documentation should provide such a guide for basic installation needs, while explaining alternative/advanced configuration at the end. Links to reference guides and documentation should be used more frequently to avoid recommending an outdated or excessively complex configuration.

- server: move most server-related info to server-configuration.md, cleanup/shorten
- server: update list of php dependencies/libraries, link to composer.json
- server: installation: support 3 install methods (from release zip, from sources, using docker)
- server: installation: use rsync instead of mv as mv results will change depending of taget directory already existing or not
- server: add example/basic usage of certbot
- server, upgrade, installation: update file permissions setup, use sudo for upgrade operations in webserver document root
- server: apache: add comments to configuration, fix and factorize file permissions setup, set cache-control header, deny access to dotfiles, add missing apache config steps, add http->https redirect example
- server: nginx: refactor nginx configuration, add comments, DO log access to denied/protected files
- server: add links to MDN for x-forwarded-* http headers explanation, cleanup/clarify robots.txt and crawlers section
- server: bump file upload size limit to 100MB we have reports of bookmark exports weighing +40MB - i have a 13MB one here
- server: simplify phpinfo documentation
- server: move backup and restore information to dedicated page
- docker: move all docker docs to Docker.md, simplify/ docker setup, add docker-compose.yml example, replace docker-101 with docker cheatsheet
- troubleshooting: move all troubleshooting documentation to troubleshooting.md

**Usage:**

- index: add getting started section on index page
- features/usage: move all usage-related documentation to usage.md, add links from the main feature list to corresponding usage docs, clarify/reword features list
- shaarli configuration: add note about configuring from web interface

**Removed:**

- remove obsolete/orphan images
- remove obsolete shaarchiver example
- remove outdated "decode datastore content" snippet

**Development:**

- development: move development-related docs (static analysis, CI, unit tests, 3rd party libs, link structure/directory, guidelines, security....) to dev/ directory
- development: Merge several pages to development.md
- **Breaking change?:** remove mentions of 'stable' branch, switch to new branch/release model (master=latest commit, release=latest tag)
- **Breaking change?:** refer to base sharing unit as "Shaare" everywhere (TODO: reflect changes in the code?) doc: update featues list/link to usage.md for details
- development: directory structure: add note about required file permissions
- .travis-ci.yml: add comments
- .htaccess: add comment

Introduction

PGP and GPG

Gnu Privacy Guard (GnuPG) is an Open Source implementation of the Pretty Good Privacy (OpenPGP) specification. Its main purposes are digital authentication, signature and encryption. It is often used by the FLOSS community to verify:

You MUST understand that presence of data in the keyserver (pools) in no way connotes trust. Anyone can generate a key, with any name or email address, and upload it. All security and trust comes from evaluating security at the “object level”, via PGP Web of trust signatures. This keyserver makes it possible to retrieve keys, looking them up via various indices, but the collection of keys in this public pool is KNOWN to contain malicious and fraudulent keys. It is the common expectation of server operators that users understand this and use software which, like all known common OpenPGP implementations, evaluates trust accordingly. This expectation is so common that it is not normally explicitly stated.

-- Phil Pennock (author of the SKS key server - http://sks.spodhuis.org/)

Trust can be gained by having your key signed by other people (and signing their key back, too :) ), for instance during key signing parties: Keysigning party HOWTO,

Generate a GPG key

gpg - provide identity information

$ gpg --gen-key

gpg (GnuPG) 2.1.6; Copyright (C) 2015 Free Software Foundation, Inc.
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.

Note: Use "gpg2 --full-gen-key" for a full featured key generation dialog.

GnuPG needs to construct a user ID to identify your key.

Real name: Marvin the Paranoid Android
Email address: marvin@h2g2.net
You selected this USER-ID:
    "Marvin the Paranoid Android <marvin@h2g2.net>"

Change (N)ame, (E)mail, or (O)kay/(Q)uit? o
We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

gpg - entropy interlude

At this point, you will:

  • be prompted for a secure password to protect your key (the input method will depend on your Desktop Environment and configuration)
  • be asked to use your machine's input devices (mouse, keyboard, etc.) to generate random entropy; this step may take some time

gpg - key creation confirmation

gpg: key A9D53A3E marked as ultimately trusted
public and secret key created and signed.

gpg: checking the trustdb
gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model
gpg: depth: 0  valid:   2  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 2u
pub   rsa2048/A9D53A3E 2015-07-31
      Key fingerprint = AF2A 5381 E54B 2FD2 14C4  A9A3 0E35 ACA4 A9D5 3A3E
uid       [ultimate] Marvin the Paranoid Android <marvin@h2g2.net>
sub   rsa2048/8C0EACF1 2015-07-31

gpg - submit your public key to a PGP server (Optional)

$ gpg --keyserver pgp.mit.edu --send-keys A9D53A3E
gpg: sending key A9D53A3E to hkp server pgp.mit.edu
