Binary Data Encoder

Build a utility that converts binary data to and from a URL-safe text representation using Base32 encoding.

Requirements

Your implementation should provide functionality to:

1. Encode binary data: Convert binary data (Uint8Array) into a Base32-encoded string
2. Decode encoded strings: Convert Base32-encoded strings back into binary data (Uint8Array)

The encoded strings should be:

• URL-safe (no special characters)
• Case-insensitive
• Compact and efficient

Test Cases

• Encoding a Uint8Array containing [72, 101, 108, 108, 111] produces the string "91JPRV3F" @test
• Decoding the string "91JPRV3F" produces a Uint8Array containing [72, 101, 108, 108, 111] @test
• Encoding an empty Uint8Array produces an empty string @test
• Decoding an empty string produces an empty Uint8Array @test

API

/**
 * Encodes binary data into a Base32 string
 * @param input - Binary data as Uint8Array
 * @returns Base32-encoded string
 */
export function encode(input: Uint8Array): string;

/**
 * Decodes a Base32 string back into binary data
 * @param input - Base32-encoded string
 * @returns Binary data as Uint8Array
 */
export function decode(input: string): Uint8Array;
