HMAC Generator

What it does

HMAC Generator helps to generate HMAC using SHA256, SHA1, MD5, AES, SHA3 and many more. Secure and one of the best tool.

Hash-based Message Authentication Code (HMAC) generator uses Algorithms and secret key to generate the HMAC. A Hashed Message Authentication Code (HMAC) is a cryptographic artifact for determining the authenticity and integrity of a message object, the usage of a symmetric key and a hash (message-digest). The HMAC might be founded on message-digest calculations along with the SHA256, MD5 etc. Ownership of an HMAC esteem does now not bargain the delicate realities as HMACs aren't reversible curios. This tool can be used as hmac sha256from codebeautify.org

  A hash array-mapped trie implementation in C2023 · github.com · ▲171

  Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

  Satoshi9000 analog BTC key generator (mechanical)2024 · ▲164

  I built this machine so I could generate Bitcoin keys that I could trust. Air-gapped and simple to use and understand (mechanical). The Satoshi 9000 demo: https://youtu.be/bJiOia5PoGE The key value proposition of the machine is that it generates analog randomness in the physical world and converts it into digital (1’s and 0’s) randomness. Seamlessly. But it occurs to me that it may have other uses beyond crypto keys for your own use, such as: * Randomized clinical trials. Clinical trials need a high degree of transparency for ethical reasons; also, for legal reasons should it…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
