  • Local Reverse Proxy

    If you're going to use a custom local domain name, you might as well use a self-signed SSL certificate. I'll use OpenSSL for this:
  • How to Resolve Node.js ERR_OSSL_EVP_UNSUPPORTED Error
    1 project | | 28 May 2024
    Are you facing the notorious ERR_OSSL_EVP_UNSUPPORTED error in your Node.js applications? This error is a common stumbling block that occurs due to changes in cryptographic operations handling introduced with Node.js version 17. The root of the problem lies in the default configuration of OpenSSL in newer Node.js versions, which restricts the use of certain algorithms. Fortunately, there are effective solutions to overcome this error, ensuring your development process remains smooth and uninterrupted.

  • Heartbleed and XZ Backdoor Learnings: Open Source Infrastructure Can Be Improved Efficiently With Moderate Funding
    2 projects | | 7 Apr 2024
    Today, April 7th, 2024, marks the 10-year anniversary since CVE-2014-0160 was published. This security vulnerability known as "Heartbleed" was a flaw in the OpenSSL cryptography software, the most popular option to implement Transport Layer Security (TLS). In more layman's terms, if you type https:// in your browser address bar, chances are high that you are interacting with OpenSSL.
  • Ask HN: How does the xz backdoor replace RSA_public_decrypt?
    1 project | | 1 Apr 2024
    At this point I pretty much understand the entire process on how the xz backdoor came to be: its execution stages, extraction from binary "test" files etc. But one thing puzzles me: how can the ifunc mechanism be used to replace something like RSA_public_decrypt? Granted this probably stems from my lack of understanding of ifunc, but I was under the impression that in order for the ifunc mechanism to work in your code, you have to explicitly mark specific function with multiple implementations with __attribute__ ((ifunc ("the_resolver_function"))). Looking at the source code of the RSA function in question, ifunc attribute isn't present:

    So how does the backdoor actually replace the call? Does this means that the ifunc mechanism can be used to override pretty much anything on the system?

  • Use of HTTPS Resource Records
    1 project | | 4 Jan 2024
    OpenSSL and Go crypt/tls has no support yet, so none of the webservers that depend on them support it. Apache, Nginx, and Caddy, they all need upstream ECH support first.

  • Encrypted Client Hello – the last puzzle piece to privacy
    4 projects | | 29 Sep 2023
    If I'm understanding the draft correctly, I think the webserver you're hosting your sites on would need it implemented as it requires private keys and ECH configuration. In the example of nginx since it uses openssl, openssl would need to implement it. I found an issue on their Github but it's still open:
