Hi all, now that I have SVN access - would it be fine if I assigned the issues that I reported and that are still open to myself? What about those already assigned? Regards, Martin ---------------------------------------- Bug #4421: [ext/openssl] Fix RSA public key encoding http://redmine.ruby-lang.org/issues/4421 Author: Martin Bosslet Status: Assigned Priority: Normal Assignee: Hiroshi NAKAMURA Category: ext Target version: 1.9.3 ruby -v: ruby 1.9.2p180 (2011-02-18 revision 30909) [i686-linux] =begin When calling RSA#to_der and RSA#to_pem on RSA public keys, they currently get encoded using i2d_RSAPublicKey and PEM_write_bio_RSAPublicKey. This encoding was specified in PKCS#1 and is specific to RSA. It is also not the default encoding used by OpenSSL itself, which rather uses the generic format generated by i2d_RSA_PUBKEY and PEM_write_bio_RSA_PUBKEY. This format is the same that is used in a certificate's SubjectPublicKeyInfo, the advantage being that the format is generic and can be used to represent public keys of all kinds, including RSA, DSA and Elliptic Curve. The attached patch will make use of the generic format for encoding RSA keys. The change should not cause compatibility problems, since RSA#initialize uses several fallback scenarios that cover public keys of both formats. The fallbacks are also re-prioritized according to these changes. Regards, Martin =end -- http://redmine.ruby-lang.org
