[Breaking Change] Services - Improve Exception Handling

[IlicMiljan]

Description of Changes

This PR introduces significant improvements in exception handling across various library services. It implements custom exceptions, replacing generic exceptions for specific scenarios, such as invalid key length in ciphers.

Additionally, new tests have been added to ensure these custom exceptions function correctly under expected conditions.

How Has This Been Tested?

Tests for the new exceptions have been added to ensure that the custom exceptions are thrown as expected in defined scenarios.
