示例1: CheckSignature

entry = GetSecurityEntry ();
if (entry == null) {
// no signature is present

Close ();
return false;
}
PKCS7.ContentInfo ci = new PKCS7.ContentInfo (entry);
if (ci.ContentType != PKCS7.Oid.signedData) {
Close ();
return false;
}
PKCS7.SignedData sd = new PKCS7.SignedData (ci.Content);
if (sd.ContentInfo.ContentType != spcIndirectDataContext) {
Close ();
return false;

ASN1 spc = sd.ContentInfo.Content;
signedHash = spc [0][1][1];
HashAlgorithm ha = null;
