CreaSign.EncryptMethod

Encrypts the specified data.

Parameters

CertName

The digital certificate, the public key of which is used for encryption. See also "Specifying the Signing Certificate".

Data

The data that should be encrypted.

Algorithm

The identifier of the symetric encryption algorithm.

Return Value

Encrypted data in PKCS#7 format or XML ducument encrypted using XML-ENC standard.

Remarks

The digital certificate specified in the CertName parameter must be installed in an appropriate certificate store. Its private key is not used in the encryption process. The data is first encrypted with a symmetric algorithm specified in the Algorithm parameter. The symmetric encryption key is then encrypted with the certificate's public key. The following symetric algorithms are supported:

• DES,
• 3DES,
• RC2,
• RC4,
• XML_3DES-RSA,
• XML_3DES-RSA_BIN,
• any other algorithm supported by the operating system. An OID can be used to identify the algorithm.

XML_3DES-RSA can be used to encrypt XML file and the encrypted data is XML file encrypted using XML-ENC standard (http://www.w3.org/TR/xmlenc-core/#sec-eg-Element).

XML_3DES-RSA_BIN can be used to encrypt binary file and the encrypted data is XML file encrypted using XML-ENC standard (http://www.w3.org/TR/xmlenc-core/#sec-eg-Arbitrary-Data).

Requirements

Requires CreaSign Pro (not supported by CreaSign Lite).
