+Keyringer
+=========
+
+Keyringer lets you manage and share secrets using GPG and git in a distributed
+fashion. It has custom commands to encrypt, decrypt, recrypt, create key pairs,
+etc.
+
+Homepage: https://keyringer.sarava.org
+
+Requirements
+------------
+
+Keyringer needs:
+
+ - Bash - http://tiswww.case.edu/php/chet/bash/bashtop.html
+ - Git - http://git-scm.com
+ - GNU Privacy Guard - http://gnupg.org
+ - Grep, awk, tail, cut, sed and other GNU tools
+
+Optional dependencies if you want to manage ssl keys:
+
+ - OpenSSL - http://www.openssl.org
+
+Installation
+------------
+
+Just clone
+
+ git clone git://git.sarava.org/keyringer.git
+
+And then leave it somewhere, optionally adding it to your $PATH environment variable.
+You can also package it to your preferred distro.
+
+Creating a keyringer repository
+-------------------------------
+
+The first step is to setup a keyring.
+
+Keyringer supports management of multiple isolated keyrings. To start
+a new keyring (or register an existing one with your config file),
+run:
+
+ keyringer <keyring> init <path> [remote]
+
+This will
+
+ 1. Add an entry at $HOME/.keyringer/config aliasing 'keyring' to 'path'.
+ 2. Initialize a git repository if needed.
+
+For example,
+
+ keyringer friends init $HOME/keyrings/friends
+
+will create an alias "friends" pointing to $HOME/keyrings/friends. Call all
+other keyring actions using this alias.
+
+If there is an existing remote keyring git repository and you just
+want to checkout it, use
+
+ keyringer friends init $HOME/keyrings/friends <repository-url>
+
+Managing recipients
+-------------------
+
+Your next step is tell keyringer the GPG key ids to encrypt files to:
+
+ keyringer <keyring> recipients edit [recipient-name]
+ keyringer <keyring> recipients ls
+
+Keyringer support multiple recipients in a per-folder style. Try it by
+creating a sample keyringer
+
+ keyringer <keyring> recipients edit closest-friends
+
+Fill it with your friends key IDs. Now encrypt a secret just for then:
+
+ keyringer <keyring> encrypt closest-friends/secret
+
+In other words, if keyringer finds a recipient file matching a given path,
+it will use it instead of the global recipients file.
+
+Managing keys
+----------------
+
+Each key has a corresponding file in your keys subdirectory.
+
+keyringer is agnostic about how you store your secrets. You may choose to have
+one key file that contains one line for each secret, e.g. a single file called
+secrets with lines such as:
+
+emma : root : secret1
+emma - /dev/hda : : secret2
+
+Or you may also have a different key file for each secret, e.g. a file called
+emma.root that contains the root passphrase for the server named emma and
+another called emma.hda with the passphrase to decrypt /dev/hda on emma.
+
+Encrypting a key
+
+ keyringer <keyring> encrypt <file>
+
+Decrypting a key (only to stdout)
+
+ keyringer <keyring> decrypt <file>
+
+Re-encrypting a key or the whole repository
+
+ keyringer <keyring> recrypt [file]
+
+Appending information to a key
+
+ keyringer <keyring> append <file>
+
+Editing a key
+
+To edit a key, use
+
+ keyringer <keyring> edit <file>
+
+Use this option with caution as it keeps temporary unencrypted data
+into keyringer temp folder and at your editor's temp files.
+
+Listing keys
+
+ keyringer <keyring> ls [arguments]
+
+Git wrapper
+-----------
+
+Keyringer comes with a simple git wrapper to ease common management tasks:
+
+ keyringer <keyring> git remote add keyringer <url>
+ keyringer <keyring> git push keyringer master
+ keyringer <keyring> git pull
+
+Configuration files, preferences and options
+--------------------------------------------
+
+ 1. Main config file: $HOME/.keyringer/config: store the location of
+ each keyring.
+
+ 2. User preferences per keyring: $HOME/.keyringer/<keyring>: managed by
+ "keyringer <keyring> preferences".
+
+ 3. Custom keyring options: $KEYRING_FOLDER/config/options: managed by
+ "keyringer <keyring> options".
+
+Using a non-default OpenPGP key
+-------------------------------
+
+If you want to use a different key other than your default for a given
+keyringer, use
+
+ keyringer <keyring> preferences add KEYID=FINGERPRINT
+
+Notes
+-----
+
+ 1. The <file> is any file inside the keys/ folder of your
+ keyring directory.
+
+ 2. Never decrypt a key and write it to the disk, except
+ if you're adding it to your personall keyring.
+
+ 3. Recipients are defined at file config/recipients.
+ Please add just trustable recipients.
+
+Concepts
+--------
+
+Basic idea is:
+
+ - Encrypt stuff with ppl's gpg pubkeys and push the output
+ in a git repo.
+
+ - Let ppl keep it in sync with the repo and the keys are
+ shared :)
+
+For "key" it's meant anything as the script work with stdin and output things to
+files, so it can be passphrases, private keys or other kind of info.
+
+It's possible to share keys using an encrypted mailing list, but the main
+difficulty is to track the message where the keys are.
+
+With theses scripts, the workflow is more or less like this:
+
+ - You have a git repo for secret keys.
+
+ - You run the "encrypt" command and paste your private key to this
+ command (so no plaintext disk write).
+
+ - The encrypt command writes an encrypted file to the repo.
+
+ - You manually add it to git and push it to remote repositories.
+
+ - Optionally, other ppl pulls the changes but they dont need to
+ decrypt anything until they need to use the keys.
+
+So it's just gpg-encrypted data atop of a git repository (one can think of a
+kind of distributed encrypted filesystem).
+
+Git was chosen to host encrypted info mostly for two reasos: easy to distribute
+and its the only VCS known to make easier repository history manipulation.
+
+One possible drawback: the repo has pubkey information attached, which can be
+linked to real ppl (and then disclose the information about who has access to a
+given key), but it's possible to:
+
+ - Keep the repo just atop of an encrypted and non-public place.
+
+ - Or to consider an integration with gpg's --hidden-recipient option.
+
+Notes: Using with GNU Privacy Guard
+-----------------------------------
+
+Exporting public keys:
+
+ gpg --armor --export <keyid>
+
+Exporting private keys (take care):
+
+ gpg --armor --export-secret-keys
+
