eCapture : Capture SSL/TLS text content without CA certificate Using eBPF

> The documentation is kind of vague, but apparently you have to re-enable it regularly.[3]
This is correct. And in the end it means more or less that setting the socket option is more of a way of sending an explicit ACK from userspace than a real setting.
It's not great for common use-cases, because making userspace care about ACKs will obviously degrade efficiency (more syscalls).
However it can make sense for some use-cases. E.g. I saw the s2n TLS library using QUICKACK to avoid the TLS handshake being stuck [1]. Maybe also worthwhile to be set in some specific RPC scenarios where the server might not immediately send a response on receiving the request, and where the client could send additional frames (e.g. gRPC client side streaming, or in pipelined HTTP requests if the server would really process those in parallel and not just let them sit in socket buffers).

mbedTLS
An open source, portable, easy to use, readable and flexible TLS library, and reference implementation of the PSA Cryptography API.
Project mention: DIY Physical Backed Tokens (EIP-5791) with ESP32 and BLE | reddit.com/r/ethdev | 2023-02-02i've used the entropy generator from MbedTLS which uses multiple sources of randomness, and seeding it additionally with the chip's mac address and the free heap size at time of creation. it would take a lot to recreate all that "noise" consistently, but i'm open to suggestions on how to make it more secure

Kore
An easy to use, scalable and secure web application framework for writing web APIs in C or Python. || This is a read-only mirror, please see https://kore.io/mail and https://kore.io/source for information on how to contribute via the mailing lists.
Project mention: What C source code or library do you use for a local server? | reddit.com/r/C_Programming | 2023-01-27https://kore.io - it’s used in a lot of nice places these days and it’s fun. (Disclaimer, it’s mine)
-

openssl
Fork of OpenSSL that includes prototype quantum-resistant algorithms and ciphersuites based on liboqs (by open-quantum-safe)
Project mention: #IranProtests: Signal is blocked in Iran. You can help people in Iran reconnect to Signal by hosting a proxy server. | reddit.com/r/technology | 2022-09-22Also: https://github.com/open-quantum-safe/openssl

Project mention: undefined method `generate' for OpenSSL::PKey::EC:Class whe starting an SSH session with a private key | reddit.com/r/ruby | 2022-08-27
JRuby doesn't use the official openssl gem which contains C extensions that compile against libopenssl, but instead uses jruby-openssl. There are a few minor compatibility issues with jruby-openssl. I've ran into the missing EC.generate method before. In theory CRuby's openssl OpenSSL::PKey::EC.generate creates a new OpenSSL::PKey::EC object and calls #generate_key, but trying that in JRuby produces a smaller EC key implying there's some data missing from the EC key, so I'm not sure if that approach is equivalent.

libresbc
An open source Session Border Controller, The SBC you dream about 🌟 LibreSBC will help you save thousands of dollars.
Project mention: LibreSBC: An open-source Session Border Controller | news.ycombinator.com | 2022-07-26 -
I recall seeing a thread somewhere saying tcpflow would not add this capability and they point people to ssldump [1][2] and even that has some limitations.

disco-c
A tiny C cryptographic library to encrypt sessions, authenticate messages, sign, hash, etc. based only on SHA-3 and Curve25519
Project mention: Liblithium: A lightweight and portable cryptography library | news.ycombinator.com | 2022-11-16Wondering if the authors heard of embedded disco[1]
-
Project mention: VESmail: Set-and-forget Email Encryption - in open testing | reddit.com/r/androidapps | 2022-04-09
The VESmail account manager guides though the setup process and provides the settings for your email client app to connect to the local VESmail app. For the convenience of the setup, the account manager suggests to use a trusted TLS connection via an end-to-end SNIF relay (https://snif.host), although a direct non-TLS connection to localhost (IMAP 7143, SMTP 7125) can be used instead.
