Hi scrypt users and tarsnap alphatesters, I've just uploaded a tarball which may be (modulo version number update) release 1.3.0 of my scrypt file encryption utility. There have been a non-trivial number of changes in the build code since scrypt 1.2.1, so I'm hoping you guys can test this and make sure we haven't broken anything. I'm asking the tarsnap alphatest list to test scrypt too, because a lot of the changes in scrypt will be in the next tarsnap release -- so think of this as a head start on alphatesting the next version of tarsnap. As always, bug reports will receive bug bounties; no need to wait for the bug to appear in a tarsnap release. You can download the scrypt code at https://www.tarsnap.com/scrypt/scrypt-1.2.99.tgz and the tarball has SHA256 hash 3a15d1f434d07f17befc91a1d9f259a67032b35fe9f3407de599e6b456f076ed . You can also see the tree from which I rolled this almost-release at https://github.com/Tarsnap/scrypt if you find it useful to crawl through VCS history. Significant functional changes since 1.2.1: * In addition to the scrypt command-line utility, a library "libscrypt-kdf" can now be built and installed by passing the --enable-libscrypt-kdf option to configure. * On x86 CPUs which support them, RDRAND and SHA extensions are used to provide supplemental entropy and speed up hash computations respectively. There are also a variety of less visible changes: Minor bug and compiler warning fixes, improvements to the test suite, and some minor corrections to source code comments. Assuming nobody yells (or the yells are things I can fix quickly and easily) I'll roll the official scrypt 1.3.0 release some time in the second half of July. - -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid -----BEGIN PGP SIGNATURE----- iF0EARECAB0WIQTq9Iu6fMd6MP78Dak4zsppDGpqbgUCXRmPbQAKCRA4zsppDGpq bqh9AJwJskgb1Zf9GufTwrtToQ78dh8RdwCfYyq+VwIRM3txMyx5XiLYNjKO+68= =LWBd -----END PGP SIGNATURE-----
