SignedCms.CheckHash SignedCms.CheckHash SignedCms.CheckHash SignedCms.CheckHash Method

Definition

The CheckHash() method verifies the data integrity of the CMS/PKCS #7 message. CheckHash() is a specialized method used in specific security infrastructure applications that only wish to check the hash of the CMS message, rather than perform a full digital signature verification. CheckHash() does not authenticate the author nor sender of the message because this method does not involve verifying a digital signature. For general-purpose checking of the integrity and authenticity of a CMS/PKCS #7 message, use the CheckSignature(Boolean) or CheckSignature(X509Certificate2Collection, Boolean) methods.
