RSA Configuration
The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.RSA Configuration Settings
| UseOAEP: Whether to use Optimal Asymmetric Encryption Padding (OAEP).Whether to use Optimal Asymmetric Encryption Padding (OAEP).
By default this value is False and the component will use PKCS1.
Note: When set to True the HashAlgorithm is also applicable when calling Encrypt and Decrypt. | |
| OAEPParams: The hex encoded OAEP parameters.This setting optionally specifies OAEP parameters to be used when UseOAEP is set to True. The specified value should be hex encoded. | |
MGF1HashAlgorithm: The MGF1 hash algorithm used with OAEP.This setting specifies the MGF1 hash algorithm used when UseOAEP is set to True. The default value is "SHA1". Possible
values are:
| |
| KeySize: The size, in bits, of the secret key.This specifies the size, in bits, of the secret key. The minimum key size for RSA is 384. The maximum key size is 4096. Note that large values such as 4096 will impact performance. The default value is 1024. | |
KeyFormat: How the public and private key are formatted.This setting controls the format of PublicKey and PrivateKey. By default
these fields hold PEM formatted public and private key data. When set to 1 (XML) the keys
are stored in a XML format. This only affects the values returned by the component; the actual keys remain
the same regardless of this setting. Possible values are:
| |
| CloseInputStreamAfterProcessing: Determines whether or not the input stream is closed after processing.Determines whether or not the input stream set by SetInputStream is closed after processing is complete. The default value is True. | |
| CloseOutputStreamAfterProcessing: Determines whether or not the output stream is closed after processing.Determines whether or not the output stream set by SetOutputStream is closed after processing is complete. The default value is True. |
Base Configuration Settings
| GUIAvailable: Tells the component whether or not a message loop is available for processing events.
In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.
In some non-GUI applications an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GuiAvailable to false will ensure that the component does not attempt to process external events. | |
| UseBackgroundThread: Whether threads created by the component are background threads.If set to True, when the component creates a thread the thread's IsBackground property will be explicitly set to True. By default this setting is False. | |
| UseManagedSecurityAPI: Tells the component whether or not to use the system security libraries or a managed implementation.
By default the component will use the system security libraries to perform cryptographic functions. This means
calls to unmanaged code will be made. In certain environments this is not desirable. To use a completely managed security
implementation set this setting to True. Setting this to True tells the component to use the internal managed implementation
instead of using the system's security API.
Note that when this value is set the product's system dll is no longer required as a reference, as all unmanaged code is stored in this file. |
