base64

Base64 encoding and decoding for Rust.

What it is

base64 provides standard and URL-safe base64 encoding and decoding with configurable padding. It supports the standard RFC 4648 alphabet, the URL-safe alphabet, and padding or no-padding variants via named engine types.

Why it is commonly used

Encoding binary data for text protocols — HTTP Authorization headers, data URIs, email attachments, JWT tokens, and any API that transmits binary payloads as ASCII text.
