It builds upon scrypt, and our implementation is able to compute native yescrypt hashes as well as classic scrypt. This is to announce the update of yescrypt to 1.0.1, available for download from the project's homepage: http://www.openwall.com/yescrypt/ The following changes have been made between 1.0.0 and 1.0.1: The included documentation has been improved, most notably adding new text files PARAMETERS (guidelines on parameter selection, and currently recommended parameter sets by use case) and COMPARISON (comparison to scrypt and Argon2). Code cleanups have been made, including removal of AVX2 support, which was deliberately temporarily preserved for the 1.0.0 release, but which almost always hurt performance with currently recommended low-level yescrypt parameters on Intel & AMD CPUs tested so far. (The low-level parameters are chosen with consideration for relative performance of defensive vs. offensive implementations on different hardware, and not only for seemingly best performance on CPUs. It is possible to change them such that AVX2 would be worthwhile, and this might happen in the future, but currently this wouldn't be obviously beneficial overall.) Alexander
