Get the DRM value for a specified parameter.
key | A parameter string as the key name. It should not be an empty string. Followings are pre-defined key names: Issuer: issuer name. Creator: creator of this file. FileID: file ID. FlowCode: flow code for application control. Order: order number. User: user name. ServiceURL: service URL for remote server. Vender: vender name. |
|
inline |
Initialize current DRM security handler.
encrypt_data | A CertificateEncryptData object. In the encryption data, cipher type should not be e_CipherNone. |
file_id | The file identity string. |
initial_key | The user specified initial key for encryption. |
|

Verify encryption parameters.
Foxit DRM maintains a set of encryption parameters for application purpose. Encryption parameters are stored in PDF file and protected by verification algorithm. So application can call this function to verify a DRM encrypted PDF document. If the verification is failed, that means the PDF document might be distorted.
