e_CipherAES = _fsdk.SecurityHandler_e_CipherAES | |
Use AES encryption algorithm, with the key length be 16 bytes (as AES-128) or 32 bytes (as AES-256, only supported in PDF 2.0). | |
e_CipherNone = _fsdk.SecurityHandler_e_CipherNone | |
Not use encryption algorithm. | |
e_CipherRC4 = _fsdk.SecurityHandler_e_CipherRC4 | |
Use RC4 encryption algorithm, with the key length between 5 bytes and 16 bytes. | |
This class represents a Foxit DRM(Digital Right Management) security handler, used for Foxit DRM encryption.
def FoxitPDFSDKPython2.DRMSecurityHandler.DRMSecurityHandler | ( | other | ) |
Constructor, with parent class object.
[in] | other | Parent class object. |
def FoxitPDFSDKPython2.DRMSecurityHandler.GetDRMValue | ( | key | ) |
Get the DRM value for a specified parameter.
[in] | key | A parameter string as the key name. It should not be an empty string. Followings are pre-defined key names:
|
def FoxitPDFSDKPython2.DRMSecurityHandler.Initialize | ( | encrypt_data, | |
file_id, | |||
initial_key | |||
) |
Initialize current DRM security handler.
[in] | encrypt_data | A certificate encrypt data object. In the encryption data, cipher type should not be FoxitPDFSDKPython2.SecurityHandler.e_CipherNone . |
[in] | file_id | The file identity string. |
[in] | initial_key | The user specified initial key for encryption. |
def FoxitPDFSDKPython2.DRMSecurityHandler.SetDRMValue | ( | key, | |
value | |||
) |
Set the DRM value for a specified parameter.
[in] | key | A parameter string as the key name. It should not be an empty string. Followings are pre-defined key names:
|
[in] | value | New value string for specified parameter. |
def FoxitPDFSDKPython2.DRMSecurityHandler.VerifyEncryptionParams | ( | ) |
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.
