crypto: Small optimizations of BCrypt

Open BiiChris opened this issue 2 years ago • 14 comments

Changes made:

  • Removed unecessary encoding and decoding between salt generation and expensiveblowfishsetup.
  • Magic cipherdata added directly into bcrypt function
  • Test salt unencoded since expensiveblowfishsetup no longer needs to unencode salt

These changes make no difference to time taken for entire algorithm due to the time spent is entirely on hashing, but it did lead to about 20% less allocations/operation on benchmarks. The size of these allocations are likely negligible compared to the total memory consumption, but nonetheless an improvement.

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.
