# Usage: Add it to your PATH and `git remove-submodule path/to/submodule`.

# Does the inverse of `git submodule add`:

`openssl pkcs12 -in [yourfile.pfx] -nocerts -out [keyfile-encrypted.key]`

What this command does is extract the private key from the .pfx file. Once entered you need to type in the importpassword of the .pfx file.  This is the password that you used to protect your keypair when you created your .pfx file.  If you cannot remember it anymore you can just throw your .pfx file away, cause you won’t be able to import it again, anywhere!.  Once you entered the import password OpenSSL requests you to type in another password, twice!. This new password will protect your .key file.

Now let’s extract the certificate:

`openssl pkcs12 -in [yourfile.pfx] -clcerts -nokeys -out [certificate.crt]`

Flask-SQLAlchemy Caching

The following gist is an extract of the article Flask-SQLAlchemy Caching. It allows automated simple cache query and invalidation of cache relations through event among other features.

Usage

retrieve one object

# pulling one User object

user = User.query.get(1)

README

The example below creates a TCP server listening on a stream (i.e. SOCK_STREAM) socket. A similar approach can be followed to create a UDP server on a datagram (i.e. SOCK_DGRAM) socket. See man systemd.socket for details.

An example server

Create an simple echo server at /opt/foo/serve.py.
