Support for GSFC-STD-8012 (Bulk Encryption)

[jlucas9]

Summary

Requesting addition for new feature to support - https://standards.nasa.gov/sites/default/files/standards/GSFC/Baseline/0/GSFC-STD-8012_Approved.pdf

Use Case

This is a published NASA standard and should be further assessed if CryptoLib should support it.

Would this just be a build flag option? Maybe move apply/process functions into interfaces.
