Base64 String Comparator Web Service

Spring boot web and Maven

This web service provides 2 HTTP endpoints that accepts JSON base64 encoded binary data on both, as it follows:

<host>/v1/diff/left
<host>/v1/diff/right

• The provided data is diff-ed and the results are available on a third end point

  /v1/diff/

• The results are provided in JSON format as following: If equal return that If not of equal size just return that If of same size provide insight in where the diffs are, actual diffs are not needed. § So mainly offsets + length in the data
