Category: Modules Group: None Status: Open Resolution: None Priority: 5 Submitted By: Gregory P. Smith (greg) Assigned to: Gregory P. Smith (greg) Summary: sha and md5 modules should use OpenSSL when possible Initial Comment: The md5 and sha (sha1) modules should use OpenSSL for the algorithms when it is available as its implementations are much faster than pythons own. Attached is an initial patch to use OpenSSL for the sha module. Its not ready for committing as is yet, but it is setup to be a generic base for all OpenSSL hashes with a little bit of work in the future. Tossing this out there for people to see how trivial it is and enjoy the speedups. diff is against HEAD but it should apply to 2.4 just fine. ---------------------------------------------------------------------- >Comment By: Gregory P.

Smith (greg) Date: 2005-02-28 10:11 Message: Logged In: YES user_id=413 a much updated patch (hashlib-patch-004.patch). it incorporates some suggestions as well as including sf patch 935454's sha256/224 and sha512/384 implementations. still not complete but shows the direction its going in (i see a segfault part way thru the test suite after running the sha512 tests). as for the private modules being under another package, i see no reason to do that since there aren't very many (how does that work for binary modules anyways?). ---------------------------------------------------------------------- Comment By: Jim Jewett (jimjjewett) Date: 2005-02-18 11:21 Message: Logged In: YES user_id=764593 Should the private modules (such as _sha) be placed in a crypto package, instead of directly in the parent/everything library? ---------------------------------------------------------------------- Comment By: Gregory P. Smith (greg) Date: 2005-02-16 22:46 Message: Logged In: YES user_id=413 hashes-openssl-002.patch replaces the sha and md5 modules with a general hashes module that wraps all hashes that OpenSSL supports. note that OpenSSLs implementations are much faster than the previous python versions as it choses versions optimized for your particular hardware. Incase python is compiled without openssl the hashes wrapper falls back on the old python sha and md5 module implementations. side note: This may be sufficient for the Debian folks to work around their random odd licensing issue. just have debian python depend on openssl; use this and remove the old md5 module/code that wouldn't get used anyways. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1121611&group_id=5470 _______________________________________________ Patches mailing list [email protected] http://mail.python.org/mailman/listinfo/patches
