# Script to remove GPG key from git-crypt
#
# It will re-initialize git-crypt for the repository and re-add all keys except
# the one requested for removal.
#
# Note: You still need to change all your secrets to fully protect yourself.
# Removing a user will prevent them from reading future changes but they will
# still have a copy of the data up to the point of their removal.

Scaling your API with rate limiters

The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.

In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.

Request rate limiter

This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.
