 | DocumentSecurityStore.VerificationParams | Represents parameters for the DocumentSecurityStore.AddVerification method. |
| OID | Represents a cryptographic object identifier. Defines IDs of many popular cryptographic items such as HASH algorithms, encoding algorithms etc. |
| OID.EncryptionAlgorithms | Represents the IDs of encryption algorithms. |
| OID.HashAlgorithms | Represents the IDs of hash algorithms. |
| OID.PKCS7 | Represents the IDs related to PKCS#7. |
| Security | Provides security and encryption services and manages permissions for GrapeCity.Documents.Pdf.GcPdfDocument objects. |
| SecurityHandlerBase | Base abstract class defining PDF Security Handler. |
| SecurityUtils | The security utility class. Provides utilities related to PDF security and signing. |
| Signature | Represents a digital signature in a PDF. |
| StandardSecurityHandler | Defines base class for Standard Security Handlers. These security handlers allow access permissions and up to two passwords to be specified for a document: an owner password and a user password. |
| StandardSecurityHandlerRev2 | Defines Standard Security Handler Revision 2. This handler uses RC4 encryption with key 40 bit length. |
| StandardSecurityHandlerRev3 | Represents a Standard Security Handler Revision 3.
This handler uses RC4 encryption with key from 40 to 128 bit length and allows to define additional permission flags. |
| StandardSecurityHandlerRev4 | Represents Standard Security Handler Revision 4.
This handler can use RC4 encryption with key 40-128 bit or AES encryption with 128 bit key and allows to define additional permission flags. |
| StandardSecurityHandlerRev5 | Represents Standard Security Handler Revision 5.
This handler always use AES encryption with key length of 256 bit, it is described in Adobe Supplement to the ISO 32000. |
| StandardSecurityHandlerRev6 | Represents Standard Security Handler Revision 6.
This handler always use AES encryption with key length of 256 bit, it is described in PDF 2.0 specification. |
