2026-01-13scrypt: fix panic on parameters <= 0Juergen Graf
Providing 0 as argument for r or p results in a panic: panic: runtime error: integer divide by zero Providing negative values for r or p returns a misleading error: scrypt: parameters are too large This change avoids the panic and introduces a new error that is returned when r or p are <= 0: scrypt: parameters must be > 0 Change-Id: I68987b27d1eedd66644d2ec9436cba364fc1d46d Reviewed-on: https://go-review.googlesource.com/c/crypto/+/731780 Reviewed-by: Michael Pratt <mpratt@google.com> Reviewed-by: Roland Shoemaker <roland@golang.org> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com> Reviewed-by: Filippo Valsorda <filippo@golang.org> Auto-Submit: Roland Shoemaker <roland@golang.org>

2021-03-17scrypt: use encoding/binary to simplify smixAndreas Auernhammer
This CL simplifies the smix implementation. It: - replaces the manual byte-int conversion with functionality from encoding/binary. - pre-computes the range `r * 32` as `R`.

2017-09-30scrypt: update recommended parameters for 2017Kevin Burke
Previously we documented recommended parameters for scrypt from 2009, which was eight years ago. Update those parameters and also provide some guidance to users for configuring those settings in 2017. On my late 2015 Macbook Pro, the scrypt benchmark with N=1<<15, r=8, p=1 completes in 91 milliseconds. Add an Example with a salt. Fixes golang/go#22082.
