x/crypto: increasing the default BCrypt cost

Open n-bruno opened this issue 2 months ago • 5 comments

Looking at git blame, it appears the DefaultCost for the Bcrypt library has remained unchanged for the past 14 years.

To keep up with modern hardware, I propose upgrading the Bcrypt library's DefaultCost from 10 to 12 to match the PHP 8.4 recent update in 2024.

Please see PHP's RFC for research on this topic, but please keep in mind the benchmarks are specific to PHP: https://wiki.php.net/rfc/bcrypt_cost_2023

Congratulations on opening your first change. Thank you for your contribution!

Next steps: A maintainer will review your change and provide feedback. See https://go.dev/doc/contribute#review for more info and tips to get your patch through code review.

Most changes in the Go project go through a few rounds of revision. This can be surprising to people new to the project. The careful, iterative review process is our way of helping mentor contributors and ensuring that their contributions have a lasting impact.

During May-July and Nov-Jan the Go project is in a code freeze, during which little code gets reviewed or merged. If a reviewer responds with a comment like R=go1.11 or adds a tag like "wait-release", it means that this CL will be reviewed as part of the next development cycle. See https://go.dev/s/release for more details.
