From: merch-redmine@... Date: 2019-08-20T03:10:15+00:00 Subject: [ruby-core:94442] [Ruby master Feature#14915] Deprecate String#crypt Issue #14915 has been updated by jeremyevans0 (Jeremy Evans). I believe the current documentation and code is intentional. I think it is best to consider `String#crypt` deprecated even if we are not emitting warnings for it and we do not have immediate plans to remove it. I would still like to remove `String#crypt`, even if that removal doesn't happen until Ruby 4. ---------------------------------------- Feature #14915: Deprecate String#crypt https://bugs.ruby-lang.org/issues/14915#change-80868 * Author: jeremyevans0 (Jeremy Evans) * Status: Rejected * Priority: Normal * Assignee: * Target version: ---------------------------------------- This method is system and implementation dependent, and the portable usage mentioned in the documentation is not truly portable (doesn't work on OpenBSD) and insecure as it uses DES. For systems that lack a crypt(3) implementation, Ruby will happily substitute a version that only supports DES. It's 2018, using DES should be avoided if at all possible. The only internal usage of String#crypt in Ruby is in Webrick, where it uses DES for basic authentication with an htpasswd file. That could and should be changed to use a more secure hash by default (bcrypt since that's the most secure htpasswd format), or at least allow the user to customize Webrick's authentication. I expect there are few if any users actively using Webrick's htpasswd support. This moves the String#crypt implementation to the string/crypt extension, but leaves the String#crypt core method. The core method prints a deprecation warning, then loads the string/crypt extension. The string/crypt extension undefines the String#crypt core method, then defines the previous implementation. Because extensions use extconf.rb instead of configure for their configuration, this ports the related configure.ac code to extconf.rb. I'm not sure that is done correctly and works on all platforms, it will need testing. For systems that lack a crypt(3) implementation, this modifies the fallback code to only define crypt_r, since that is the only function that String#crypt will call in that case. While the patch just deprecates String#crypt, I think we should plan to remove support from ruby: 2.6: core method deprecated 2.7: core method removed, string/crypt extension ships with ruby 2.8: string/crypt extension moves to external gem, not shipped ---Files-------------------------------- 0001-Deprecate-String-crypt-move-implementation-to-string.patch (20.5 KB) 0001-Deprecate-String-crypt.patch (7.48 KB) 0001-Deprecate-String-crypt.patch (7.35 KB) 0001-Deprecate-String-crypt.patch (7.43 KB) deprecate-string-crypt.patch (6.7 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
