# base62.rs
A library for encoding/decoding byte arrays to/from a base62 strings.
# Alphabet
This library defines the Base62 alphabet as the following characters:
```0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz```
# How it works
A byte array (leading zeros allowed) is prepended with `0x01` and is treated
as a big-endian unsigned integer (`num_bigint::BigUint`).
This number is repeatedly divided by our base, `62`, and each remainder is used as an index into our alphabet above,
producing the base62 encoded string.
To decode, we run the algorithm above in reverse.
# Example
```rust
fn main() {
let input = vec![0xDE,0xAD,0xBE,0xEF];
let encoded = base62::encode(&input);
println!("0xDEADBEEF = {}", encoded);
let deadbeef = base62::decode("JsoUl8").unwrap();
let input = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt";
let encoded = base62::encode(input.as_bytes());
println!("lorem... = {}", encoded);
let loremipsum = base62::decode("Inj62xrWzFT5RgFoP72ZkfbrMabXdyZeYGijtTt8zuBN4XvHvEw6x2pk2BtdepGle57axcSeY2ixeXqOvwpE2VaEE3pHeeumHvIbZf0qUUxRBg99NrIALFCE").unwrap();
}
```
