 1 | # sqlite-base64

 3 | A base64 encoder/decoder for SQLite, written in Rust. See [`sqlite-loadable-rs`](https://github.com/asg017/sqlite-loadable-rs), the framework that makes this extension possible.

 6 | ## WORK IN PROGRESS
 7 | 
 8 | This extension isn't 100% complete yet, but hoping to release soon! Once it's ready, you'll be able to do things like:
 9 | 
10 | ```sql
11 | select base64_decode('YWxleA=='); -- 'alex'
12 | select base64_encode('angel'); -- 'YW5nZWw='
13 | ```
14 | 
15 | In the meantime, checkout the very-new and more offical [base64.c](https://github.com/sqlite/sqlite/blob/master/ext/misc/base64.c) SQLite extension.
