I am not a cryptography expert but I am interested in the field. Having said that: I am lately having an hard time understanding the actual strength of a crypto suite based on the underlying problem, the sized of the material and the computation strength needed to break it either via optimization and parallelism capabilities.

Is it? How do I verify such claim?

Yeah, but how much time it required? and what about the resources? It is just a number, it is not all the 861 bits n numbers.
