𝕂𝚞𝚋𝚒𝚔ℙ𝚒𝚡𝚎𝚕Choosing a hash function for 2030 and beyond: SHA-2 vs SHA-3 vs BLAKE3As everyone knows, "temporary fixes" are nothing but temporary. Unfortunately, the same is true for cryptography: unless security is your core value-proposition, crypto algorithms are almost never updated, and that's how we end up with SHA1-hashed password in 2024 🤦‍♂️# <a href="https://kerkour.com/fast-secure-hash-function-sha256-sha512-sha3-blake3" rel="nofollow noopener" translate="no" target="_blank">https://kerkour.com/fast-secure-hash-function-sha256-sha512-sha3-blake3</a><a href="https://chaos.social/tags/hash" class="mention hashtag" rel="nofollow noopener" target="_blank">#hash</a> <a href="https://chaos.social/tags/hashfunctions" class="mention hashtag" rel="nofollow noopener" target="_blank">#hashfunctions</a> <a href="https://chaos.social/tags/coding" class="mention hashtag" rel="nofollow noopener" target="_blank">#coding</a> <a href="https://chaos.social/tags/sha2" class="mention hashtag" rel="nofollow noopener" target="_blank">#sha2</a> <a href="https://chaos.social/tags/hashing" class="mention hashtag" rel="nofollow noopener" target="_blank">#hashing</a> <a href="https://chaos.social/tags/itsec" class="mention hashtag" rel="nofollow noopener" target="_blank">#itsec</a> <a href="https://chaos.social/tags/itsecurity" class="mention hashtag" rel="nofollow noopener" target="_blank">#itsecurity</a> <a href="https://chaos.social/tags/sha3" class="mention hashtag" rel="nofollow noopener" target="_blank">#sha3</a> <a href="https://chaos.social/tags/BLAKE3" class="mention hashtag" rel="nofollow noopener" target="_blank">#BLAKE3</a> <a href="https://chaos.social/tags/fast" class="mention hashtag" rel="nofollow noopener" target="_blank">#fast</a> <a href="https://chaos.social/tags/fastapi" class="mention hashtag" rel="nofollow noopener" target="_blank">#fastapi</a> <a href="https://chaos.social/tags/feature" class="mention hashtag" rel="nofollow noopener" target="_blank">#feature</a>
