Or yet another way: Encrypt the value of the single private bstr and stick resulting tagged COSE_Encrypt(0) into the corresponding field. However, if you do this with Ed25519 or Ed448 keys, make sure the public key gets authenticated (e.g., external ad), or you got a nasty security hole! -Ilari _______________________________________________ COSE mailing list [email protected] https://www.ietf.org/mailman/listinfo/cose
