Program : Regular hash algorithms

In this program, you are required to invoke the md5 and sha256 algorithms that are implemented in hashlib build-in library. Your program does the following:

Read the input byte array as a hex string.
Output the md5 digest of the input, as a hex string.
Output the md5 digest of the input, as a Base64 string.
Output the sha256 digest of the input, as a hex string.
Output the sha256 digest of the input, as a Base64 string…

Example Input 1
