I have encountered a number of implementations of algorithms for converting a byte array to a hexadecimal string in many languages:

Why is this conversion used so often?
What are the advantages of storing byte arrays as hexadecimal strings?

How would you store a byte array? – Andrew Henle Sep 22 '15 at 16:50
To examine its contents programatically, for example. – cadaniluk Sep 22 '15 at 16:52

For example:

To store in a file with a format that doesn't support binary, e.g. CSV.
To store in a database field that doesn't support binary.
To send in a protocol that doesn't support binary.
To embed in other content that doesn't support binary, e.g. XML and JSON.
To display to a user.
Many other reasons...
