# Base64 Decoder

## What is Base64?

Base64 is a group of binary-to-text encoding schemes that represent binary data (more specifically, a sequence of 8-bit bytes) in an ASCII string format by translating the data into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding. Each non-final Base64 digit represents exactly 6 bits of data. Three bytes (i.e., a total of 24 bits) can therefore be represented by four 6-bit Base64 digits.

## Examples

Original text:```
test string
```

Base64 encoded text:

```

```
