Joseph and Merlin, I agree with you that we should make the DigestMethod child for RSA-OAEP and also the DigestMethod child for the AgreementMethod in section 5.5 required, since they are needed in the computation. The text for RSA-OAEP is still not clear. I suggest the following: ---------------------- The RSAES-OAEP-ENCRYPT algorithm , as specified in RFC 2437 [ PKCS1], takes three parameters: a MANDATORY message digest function, a mandatory mask generation function and an OPTIONAL encoding octet string OAEPparams. The message digest function is indicated by the Algorithm attribute of a child ds:DigestMethod element, and the mask generation function is always MGF1WithSHA1, where both are used in the EME-OAEP-ENCODE as part of RSAES-OAEP-ENCRYPT. The encoding octet string is the base64 decoding of the content of an optional OAEPparams child element . If no OAEPparams child is provided, a null string is used. -------------------- Jiandong Guo Phaos Technology http://www.phaos.com
