base64

Base64 encode and decode strings.

Import

import base64

The encode module and crypto module also expose base64 functions. This module is the dedicated, minimal interface.

Functions

base64.encode(data: str) -> str

Encode a string to base64.

base64.decode(data: str) -> str

Decode a base64 string back to its original bytes.

Examples

scratch.xs

import base64

let encoded = base64.encode("hello, world")
println(encoded)               -- aGVsbG8sIHdvcmxk

let decoded = base64.decode(encoded)
println(decoded)               -- hello, world

-- round-trip
let data = "XS language 2026"
println(base64.decode(base64.encode(data)) == data)  -- true
