encoding/asn1: sort order of 'SET of' components during Marshal #38228
Conversation
Per X690 Section 11.6 sort the order of SET of components when generating DER. This CL makes no changes to Unmarshal, meaning unordered components will still be accepted, and won't be re-ordered during parsing. In order to sort the components a new encoder, setEncoder, which is similar to multiEncoder is added. The functional difference is that setEncoder encodes each component to a [][]byte, sorts the slice using a sort.Sort interface, and then writes it out to the destination slice. The ordering matches the output of OpenSSL. Fixes golang#24254 Change-Id: Iff4560f0b8c2dce5aae616ba30226f39c10b972e

Hello, Its self-signature is OK when verified with GoLang, OpenSSL, and other tools, but KO with GnuTLS and BouncyCastle. I understand that GoLang (like several other tools and run-times, to be honest) omits the DER-encoding pass prescribed by RFC2986, when verifying the CSR self-signature, wrongly assuming that the signed data are already DER-encoded -- which is not necessarily the case, as in the attached example. |

In order to sort the components a new encoder, setEncoder, which is similar
to multiEncoder is added. The functional difference is that setEncoder
encodes each component to a [][]byte, sorts the slice using a sort.Sort
interface, and then writes it out to the destination slice. The ordering
matches the output of OpenSSL.
