secretcrypt 1.0.0

Encrypt project secrets

py-secretcrypt
==============

|Circle CI|
|Codecov|

Utility for keeping your secrets encrypted. Also has a `Go
version <https://github.com/Zemanta/go-secretcrypt>`__.

For example, you have the following configuration file

::

MY_SECRET=VerySecretValue!

but you can't include that file in VCS because then your secret value
would be exposed.

With **secretcrypt**, you can encrypt your secret using your AWS KMS
master key aliased *MyKey*:

.. code:: bash

$ encrypt-secret kms alias/MyKey
Enter plaintext: VerySecretValue! # enter
kms:region=us-east-1:CiC/SXeuXDGRADRIjc0qcE... # shortened for brevity

# --- or --
$ echo "VerySecretValue!" | encrypt-secret kms alias/MyKey
kms:region=us-east-1:CiC/SXeuXDGRADRIjc0qcE... # shortened for brevity
# only use piping when scripting, otherwise your secrets will be stored
# in your shell's history!

use that secret in my config file

.. code:: python

from secretcrypt import Secret
MY_SECRET=Secret('kms:region=us-east-1:CiC/SXeuXDGRADRIjc0qcE...') # shortened for brevity

and get the plaintext like

.. code:: python

print MY_SECRET.get()
# VerySecretValue!

If you are using very sensitive secrets, you can ensure the plaintext
is not kept in memory and is only encrypted on demand by using a stricter
version:

.. code:: python

from secretcrypt import StrictSecret
MY_SECRET=StrictSecret('kms:region=us-east-1:CiC/SXeuXDGRADRIjc0qcE...') # shortened for brevity

and get the plaintext like

.. code:: python

print MY_SECRET.decrypt()
# VerySecretValue!

KMS
---

The KMS option uses AWS Key Management Service. When encrypting and
decrypting KMS secrets, you need to provide which AWS region the is to
be or was encrypted on, but it defaults to ``us-east-1``.

So if you use a custom region, you must provide it to secretcrypt:

.. code:: bash

encrypt-secret kms --region us-west-1 alias/MyKey

Local encryption
----------------

This mode is meant for local and/or offline development usage. It
generates a local key in your %USER\_DATA\_DIR% (see
`appdirs <https://pypi.python.org/pypi/appdirs>`__), so that the key
cannot be accidentally committed to CVS.

It then uses that key to symmetrically encrypt and decrypt your secrets.

Password encryption - interactive only
-------------------

The password encryption mode should not be used in your application - it is
meant for easily sharing secrets among developers. It interactively prompts
the user for a password when encrypting the secret. When decrypting, it
prompts for the password again.
