Win-Base64 API

Description

A simple wrapper over the Windows API Base64 Encoding and Decoding

1. String to Base64 (encode)
2. Base64 to String (decode)

Sample Code

use win_base64::decode;
use win_base64::encode;
let text = "What's up?😊🥘🍲🚩🏁🚀👌😁👍😍❤️💕🎶";
let base64_string = encode(&text)?;
let decoded_text = decode(&base64_string)?;
// If it worked, text and decoded_text would be the same
println!("Original: {}", text);
println!("Decoded : {}", decoded_text);

OUTPUT

Original: What's up?😊👌😁👍😍❤️💕🎶
Decoded: What's up?😊👌😁👍😍❤️💕🎶

Yes this supports Emojis.

Similar code to base64 library

let a = "hello world";
let b = "aGVsbG8gd29ybGQ=";

assert_eq!(encode(a)?, b);
assert_eq!(a, &decode(b)?[..]);

Multiple Decodes

1. Decode as &mut [u8] (decode_as_mut8)
   Probably the fastest
   But the sizes are to be specified manually.
   So probably the riskiest as well.

    let text = "What's up?";
    let base64_string = encode(&text)?;
    let mut decoded_arr = vec![0u8; 10];
    use win_base64::decode_as_mut8;
    decode_as_mut8(&base64_string, &mut decoded_arr)?;
    // If it worked, text and decoded_text would be the same
    println!("Original: {}", text);
    println!("Decoded : {:?}", decoded_arr);

2. Decode as Vec<u8> (decode_as_vecu8)
   Allocates a vec of the correct size Returns this vec with decoded values Safer than mut u8 as it knows the decoded size

   let text = "What's up?";
   let base64_string = encode(&text)?;
   use win_base64::decode_as_vecu8;
   let decoded_vec = decode_as_vecu8(&base64_string)?;
   // If it worked, text and decoded_text would be the same
   println!("Original: {}", text);
   println!("Decoded : {:?}", decoded_vec);

3. Decode as String (decode)
   Present in top most example

   use win_base64::decode;
   use win_base64::encode;
   let text = "What's up?😊🥘🍲🚩🏁🚀👌😁👍😍❤️💕🎶";
   let base64_string = encode(&text)?;
   let decoded_text = decode(&base64_string)?;
   // If it worked, text and decoded_text would be the same
   println!("Original: {}", text);
   println!("Decoded : {}", decoded_text);
