# 5. Base64

## Challenge Description:

Another common encoding scheme is Base64, which allows us to represent binary data as an ASCII string using an alphabet of 64 characters. One character of a Base64 string encodes 6 binary digits (bits), and so 4 characters of Base64 encode three 8-bit bytes.\
\
Base64 is most commonly used online, so binary data such as images can be easily included into HTML or CSS files.\
\
Take the below hex string, *decode* it into bytes and then *encode* it into Base64.\

\ <i class="fa-lightbulb">:lightbulb:</i> In Python, after importing the base64 module with `import base64`, you can use the `base64.b64encode()` function. Remember to decode the hex first as the challenge description states.

## My Solution:

We can import the base64 library and invoke its b64encode function to encoded the decoded string from hex:

```python
import base64

EncodedData = "72bca9b68fc16ac7beeb8f849dca1d8a783e8acf9679bf9269f7bf"

FromHex = bytes.fromhex(EncodedData)

print("Here is your flag:")
print(base64.b64encode(FromHex).decode())
```

## The Flag:

```bash
crypto/Base+64+Encoding************/
```
