How does Argon2id compare to bcrypt in terms of security and performance for Cloudflare Workers?

Both Argon2id and bcrypt are strong password hashing algorithms. Argon2id is generally considered more secure against GPU-based attacks and offers better resistance to side-channel attacks. However, bcrypt has been around longer and has a more mature ecosystem. For Cloudflare Workers, Argon2id's potentially higher computation cost can be a concern. bcrypt might offer slightly better performance in some cases, but the security benefits of Argon2id usually outweigh the performance difference. Benchmark both algorithms with your specific parameters to determine the best fit.
