One of the most widely used digital signature formats is CMS - cryptographic message syntax, aka PKCS#7. It is used, e.g. in S/MIME messages.
It is also used for detached signatures on files. E.g., since 2009, the IETF has signed its internet-drafts. See http://www.ietf.org/id- info/idsignatures.html The IETF recommends, right in the RFC for signing internet drafts, to use openssl to verify signatures. http://www.ietf.org/rfc/rfc5485.txt But as this bug documents, when the openssl package in Ubuntu is used as documented, it doesn't work: $ openssl cms -verify -CAfile comodo.pem -content draft-abarth-mime-sniff-06.txt -inform DER -in *p7s openssl:Error: 'cms' is an invalid command. Is there a really good reason for disabling this feature? If not, please add it back. If so, please provide another package with it enabled. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/380424 Title: Recompile with enable-cms -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
