Why we cannot wait for better post-quantum signature algorithms

What this post added

This post details the latest developments in post-quantum signature algorithms, comparing candidate algorithms like FN-DSA, HAWK, and others against standardized ML-DSA and classical algorithms. It analyzes their sizes, CPU times for signing and verification, and discusses their strengths and weaknesses, particularly for use in TLS. The post highlights the trade-offs between different algorithms, such as SQIsign's small signatures but slow signing, and the lack of a single 'all-star' algorithm, necessitating a pragmatic approach to migration using available algorithms like ML-DSA while continuing research into more optimal future solutions.
