Keybase is an open source data-encryption-themed command line program that hosts a directory of public social network keys and identify proofs. Developers can implement the Keybase API to access their directory programmatically. HTTP GET/POST requests can be sent with a JSON encoded structure to receive a given user's username, to calculate password hashes, and to login with a hash and csrf_token. The API can be embedded into clients or 3rd party applications, and all functionalities can also be utilized on Keybase.io's website and command line interface.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
