- Ensure data integrity throughout the process
- Generate a jar file for the implemented solution
- Provide recommendations for suitable Java libraries to use with RFC8818

Ideal Skills and Experience:
- Strong proficiency in Java programming
- Experience with encryption algorithms and data integrity protocols
- Familiarity with JSON data structures
- Ability to recommend and integrate suitable Java libraries for RFC8818

I am open to library recommendations and look forward to your expert suggestions to achieve a robust solution.
