Base64 encoding

Use encodeBase64() or encodeBase64NoPadding() to omit padding. decodeBase64() requires padding while decodeBase64IgnorePadding() ignores padding entirely. A URL-safe variant (base64url) versions for each method is also available.

import { encodeBase64, decodeBase64 } from "@oslojs/encoding";

const data: Uint8Array = new TextEncoder().encode("hello world");
const encoded = encodeBase64(data);
const decoded = decodeBase64(encoded);

import { encodeBase64url, decodeBase64url } from "@oslojs/encoding";

const data: Uint8Array = new TextEncoder().encode("hello world");
const encoded = encodeBase64url(data);
const decoded = decodeBase64url(encoded);
