Encrypting and Decrypting Data
[CAPICOM is a 32-bit only component that is available for use in the following operating systems: Windows Server 2008, Windows Vista, and Windows XP. Instead, use the .NET Framework to implement security features. For more information, see Alternatives to Using CAPICOM.]

CAPICOM does not support the PKCS #7 EncryptedData content type but uses a non-standard ASN structure for EncryptedData. Therefore, only CAPICOM can decrypt a CAPICOM EncryptedData object.
The following sections show examples for encryption and decryption tasks:
