For some time CMS did not support ECDSA (recipient public keys),
only RSA was supported. Has that changed recently? One needs to
recipient public keys to encrypt the message key to each recipient,
which is different from the sender key used for signing. There was
no code for that last time I looked, is there a suitable standard
for using ECDSA with CMS recipients? I just tried with 1.0.1e and
could only encrypt to an RSA recipient.
