Re: Signing a SignedData object with RSA

Since neither the CMS spec nor PKCS#7 states this explicitly, I'd very
much appreciate to have the following confirmed - or corrected: 

Section 12 will provide thin information.

When signing a SignedData object with RSA keys: 
- the signature is to be formed according to PKCS#1, and this is just
the value of the signature OCTET STRING in the SignerInfo object

Correct.

- the signatureAlgorithm of the SignerInfo is to be a proper signature
algorithm, like sha1WithRSASignature

Correct.
