That is the same thing: COSE_Encrypt is layer0, COSE_Recipient is layer1+. > We can’t apply this to -29 and friends, but we can for anything > we do going forward. -29 and friends do not use Enc_structure. But there are algorithms that do use Enc_structure, even at layer1+ (so in COSE_Recipient), namely 1 and friends (1-3, 10-13, 24 and 30-33). -29 and friends are not even bulk ciphers, so are always recipients (layer1+). -Ilari _______________________________________________ COSE mailing list -- [email protected] To unsubscribe send an email to [email protected]
