RFC 7170 and the current draft have diverged in how IMSK is calculated. In short:1. RFC 7170 pass EMSK to TLS-PRF whereas the draft passes both EMSK and MSK to TLS-PRF. 2. While RFC 7170 adjusts only MSK to 32 octet length, the draft adjusts both EMSK and MSK.See section 5.2 "Intermediate Compound Key Derivations" in the diff for the current changes: https://author-tools.ietf.org/diff?doc_1=RFC7170&doc_2=draft-ietf-emu-rfc7170bis-13%2F <https://author-tools.ietf.org/diff?doc_1=RFC7170&doc_2=draft-ietf-emu-rfc7170bis-13%2F>I've created a pull request with more details about which two commits have lead to this change and my suggested fix.https://github.com/emu-wg/rfc7170bis/pull/27Alex, please comment. I've discussed this with a colleague and we think the current draft would break compatibility with the existing implementations.-- Heikki Vatiainen h...@radiatorsoftware.com _______________________________________________ Emu mailing list Emu@ietf.org https://www.ietf.org/mailman/listinfo/emu
