Provos: Bcrypt at 25

Niels Provos reflectson 25 years of experience with Bcrypt and ponders the future of passwordsecurity in a ;login article.

Bcrypt's endurance can be attributed to several other factorsbeyond our intentional algorithm design. Its wide availability inopen-source implementations has facilitated widespread adoption andintegration into various systems. According to Wikipedia, there areimplementations of bcrypt in C, C++, C#, Embarcadero Delphi,Elixir, Go, Java, JavaScript, Perl, PHP, Python, andRuby. Moreover, bcrypt's focus on computational cost scaling makesit an attractive choice for large Internet services compared tonewer algorithms like Argon2, which also scale in memoryconsumption.
