A base64 encoder/decoder for SQLite, written in Rust. See sqlite-loadable-rs, the framework that makes this extension possible. md).

This extension isn't 100% complete yet, but hoping to release soon! Once it's ready, you'll be able to do things like:

select base64_decode('YWxleA=='); -- 'alex'
select base64_encode('angel'); -- 'YW5nZWw='

In the meantime, checkout the very-new and more offical base64.c SQLite extension.
