Information
-----------

[](#information)

This library is a tool to assist in the conversion of Multibase/Multicodec strings and **did:key** method spec keys to JWK, and vice versa. It utilizes Multibase/Multicodec, Simplito-EC, and JWT Framework to aid in these conversions.

For more information on the **did:key** spec, please read the current unofficial draft [here](https://w3c-ccg.github.io/did-method-key/).

Currently, this libary only supports the following curves:

- secp256k1
- nistp384

OpenSSL and Windows
-------------------

[](#openssl-and-windows)

In order for key generation to work on Windows machines, this [Installation](https://www.php.net/manual/en/openssl.installation.php) documentation must be done correctly, specifically regarding `openssl.cnf`.
