> I feel like this really only makes sense if pyca/cryptography had planned on adding the Rust dependency from the very beginning (or from very early on). Is there any indication that was the case?
I am sure this idea surfaced several times in IRC or possibly in the mailing lists. Certainly, the authors have been toying with handling ASN.1 in rust since 2015 , which I guess will be the next logical step.
I do agree that this is mostly a political stance. pyca/cryptography is a wrapper sandwiched between a gigantic runtime written in C (CPython/PyPy) and a gigantic library written in C (openssl).
The addition of Rust as dependency enables the inclusion of just 90 lines of Rust  where the only part that really couldn't be implemented in pure Python is a line copied from OpenSSL  (i.e. it was already available), and which is purely algebraic, therefore not mitigating any real memory issue at all (the reason to use rust in the first place).
The change in this wrapper (pyca/cryptographic) does not move the needle of security in any significant way, and it is really only meant to send the signal that adding Rust in all other Python packages and especially in the runtime itself will now come at no (political) cost.
A modern, portable, easy to use crypto library.Project mention: I wrote a literate state of the art random number library and integrated explanation in c | reddit.com/r/C_Programming | 2021-01-31
Get performance insights in less than 4 minutes. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.
s2n : an implementation of the TLS/SSL protocolsProject mention: LibreSSL Languishes on Linux | news.ycombinator.com | 2021-01-04
I would be interested in the other SSL implementations:
Are these subpar implementations or there are other reasons not to use these?
An open source, portable, easy to use, readable and flexible SSL libraryProject mention: C Deep | dev.to | 2021-02-27
mbed TLS - Another crypto implementation. Apache-2.0
Small portable AES128/192/256 in C
The future of online communications.Project mention: discord.... | reddit.com/r/privacy | 2021-02-28
Tox has experimental crypto and major vulnerabilities. I wouldn't recommend using it and expecting reasonable security.
Easy to use cryptographic framework for data protection: secure messaging with forward secrecy and secure data storage. Has unified APIs across 14 platforms.
wolfSSL (formerly CyaSSL) is a small, fast, portable implementation of TLS/SSL for embedded devices to the cloud. wolfSSL supports up to TLS 1.3!Project mention: Max HTTPS throughput on ESP32? | reddit.com/r/esp32 | 2021-02-26
You mention mbedtls, but for an example I was able to find that wolfssl lists some benchmarks and notice that under hardware acceleration, AES CBC gives OK performance while AES GCM looks pretty bad.
LibTomCrypt is a fairly comprehensive, modular and portable cryptographic toolkit that provides developers with a vast array of well known published block ciphers, one-way hash functions, chaining modes, pseudo-random number generators, public key cryptography and a plethora of other routines.Project mention: C Deep | dev.to | 2021-02-27
libtomcrypt - Fairly comprehensive, modular and portable cryptographic toolkit. Public domain.
LibreSSL Portable itself. This includes the build scaffold and compatibility layer that builds portable LibreSSL from the OpenBSD source code. Pull requests or patches sent to [email protected] are welcome.Project mention: [gentoo-dev] [News review] LibreSSL support discontinued | reddit.com/r/Gentoo | 2021-01-03
On the plus side they have Ed25519, on the negative side we don't have BLAKE2 or X25519, etc.
