| 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 FoxitPDFSDKPython3.DRMSecurityHandler.DRMSecurityHandler | ( | other | ) |
Constructor, with parent class object.
| [in] | other | Parent class object. |
| def FoxitPDFSDKPython3.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 FoxitPDFSDKPython3.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 FoxitPDFSDKPython3.SecurityHandler.e_CipherNone . |
| [in] | file_id | The file identity string. |
| [in] | initial_key | The user specified initial key for encryption. |
| def FoxitPDFSDKPython3.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 FoxitPDFSDKPython3.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.
