Hi
draft-nir-ipsecme-chacha20-poly1305 currently specifies three transforms: 1. chacha20 as a stand-alone cipher 2. Poly1305 as a stand-alone MAC 3. ChaCha20-Poly1305 as an AEAD. Some people in the room said that we should only do the AEAD and skip the stand-alone algorithms. This would prevent SAs with combinations such as ChaCha20 + HMAC-SHA1 or AES-128-CBC + Poly1305. I'm not saying whether we need or don't need these combinations. I don't see much use for them personally. My question to the list now is whether everyone agrees that it's fine to drop them and leave only the combined mode algorithm in the draft. Thanks Yoav
