[ruby-core:64118] [ruby-trunk - Feature #10098] [PATCH] Timing-safe string comparison for OpenSSL::HMAC

ruby-core #64118
Issue #10098 has been updated by Matt U. File tsafe_inline.patch added What's your thoughts on this new patch? At the moment I'm using OSX and Linux, unable to test `timingsafe_memcmp()` and `consttime_memequal()`. ---------------------------------------- Feature #10098: [PATCH] Timing-safe string comparison for OpenSSL::HMAC https://bugs.ruby-lang.org/issues/10098#change-48128 * Author: Matt U * Status: Open * Priority: Normal * Assignee: * Category: ext/openssl * Target version: next minor ---------------------------------------- I could be totally wrong, but it seems the standard library doesn't provide a reliable way of comparing hashes in constant-time. * The docs for `OpenSSL::HMAC` encourage the use of `Digest#to_s` (see: http://ruby-doc.org/stdlib-2.1.0/libdoc/openssl/rdoc/OpenSSL/HMAC.html#method-c-new ) * Ruby's string comparison uses memcmp, which isn't timing safe (see: http://rxr.whitequark.org/mri/source/string.c#2382 ) With this patch I propose to add an additional method, `OpenSSL::HMAC#verify`, which takes a binary string with a digest and compares it against the computed hash. ---Files-------------------------------- hmac-timing.patch (2.5 KB) hmac-timing.patch (2.48 KB) tsafe_eql.patch (2.48 KB) tsafe_inline.patch (3.51 KB) -- https://bugs.ruby-lang.org/
