Quick Note (Mini-Manifesto):

Before this is forgotten, understand that despite the seemingly academic nature of what's being posted here (it is academic), there is still a lot of controversy and government oversight/control with regards to cryptography.

Thus, there is no telling how long this channel remains up.

This may seem silly when considering the fact that this channel is merely posting links that lead to fairly formal, technical resources and explainers regarding cryptography - but readers should still remember that cryptography is still heavily monitored in all countries.

Permission from the gov't / DoD (if you're in the U.S.) must be sought if you're looking to build a truly robust, cryptographic application or tool and more than likely, you will not receive that blessing without being a willing & cooperative party.

This channel and its author(s) do not work with the government. This channel believes in education & the spread of knowledge. This channel does not think that knowledge should be compromised by government interests or its paranoia regarding alleged anti-state threats and an increasing fetish to monitor each and every single detail & aspect of a citizen's life.
Often times, these harsh overbearing measures are nothing more than a lazy substitute for making the desperately needed social reformations that will lead to a better society and world.

Instead of spending billions on surveillance to prevent terrorist attacks (especially domestic-borne ones), governments should consider pouring at least an equal amount of funds into mental health resources, affordable & convenient access to therapy, and intensive studies into our children's school curriculum with the intent of finding out how we can enrich them on a spiritual (not religious, spiritual; yes, there's a clear difference) and mental level rather than just intellectually. Human beings must grow beyond intellectual exploits. Our lives are built on interpersonal relationships - family, friends, lovers, dreams and desires, etc. We have sorely neglected this fact in the upbringing of our children and the horrifying results in society have become apparent.

Neglecting this in favor of intense scrutiny and compromising, illegal (under FISA in the U.S.) surveillance is a major disservice to society at large. And until the root of the issue is solved, horrible acts of seemingly random violence will continue.

Compromising freedom of thought, speech, and knowledge only compounds these issues and helps to breed a populace of malleable, obedient minds that are ironically much more susceptible to falling victim to poisonous ideologies.

To be clear, this channel does not use laws to govern its compass - but it is not anarchistic. Laws, while meant to preserve order and help mold society toward the best version of itself, often falls well short of that goal.

In the United States, there were several laws at one point that criminalized anyone that dared assist a wrongfully captured/kidnapped slave to freedom. The Nazi Party's regime in Germany goes without saying.

As citizens, it is our responsibility to ensure that we retain our moral dignity & compass, even during the times when our governments collectively fail to do the same.

With that being said, this channel does not advocate the use of cryptography for violence, harming others, human/sex trafficking of any sort, for any gender and for any age, or subversive plots to enact evil - for any reason, politically-motivated or otherwise.

To conclude, this channel isn't here to make a political statement - just simply host information related to cryptography because its a critical underpinning of society. Without encryption, nothing is protected. It is essential to the functioning of society in this digital age.

So without further ado, let us continue.

Homepage (Overview)

Title: Cryptography software tools for Visual Basic and C/C++/C# developers


Denoscription: The CryptoSysTM family of programming interfaces provides cryptography toolkits for developers.



This tool has a lot of CLI commands & pre-set functions along w strong cryptography baked into it to facilitate the analysis of Bitcoin transactions with a level of flexibility that really can't be found w other tools.

'Homepage' for 'Cryptosys' (tool referenced above), features four useful products:

A) CryptoSys PKI (used in the source above; allows for public-key cryptography analysis like what we see in Bitcoin)

B) CryptoSys API ( provides 'symmetrical' encryption using block ciphers like AES and Triple DES; stream ciphers ArcFour, Salsa and ChaCha20 ; HMAC, CMAC and KMAC message authentication algorithms, SHA-1 / SHA-2 and SHA-3 hash functions ) = https://www.cryptosys.net/api.html

C) SC14N [XML Canonicalization] ( SC14N performs the canonicalization (C14N) transformation you need to do when creating signed XML documents using XML-DSIG. It can carry out both "inclusive" and "exclusive" canonicalization. Includes a command-line interface ) = https://www.cryptosys.net/sc14n/index.html

D) FS Firma SAT ( a specialist product to sign and analyze digital tax receipts [Comprobantes Fiscal Digital] as specified by the Servicio de Administración Tributaria [SAT] in Mexico. Includes a command-line interface ) = https://www.cryptosys.net/firmasat/index.html

Homepage shows that these tools are very regularly updated. Note that SHA3 is a PQ algorithm (in the NIST competition currently).
