SMIME Configuration
The class 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 class, access to these internal properties is provided through the Config method.SMIME Configuration Settings
| ApplyB64Encoding: Instructs the class to base64 encode the message when signing or encrypting.This setting allows you to control the base64 encoding of the resulting message. By default,
this value is true, and the message will be base64 encoded when signing or encrypting.
NOTE: When signing, this config may only be used when DetachedSignature is false. | |
| CSP: The Cryptographic Service Provider.For the Win32 editions, the name of the Cryptographic Service Provider used to provide
access to encryption/decryption and signature operations.
NOTE: This config may only be used when the UseCryptoAPI is true. | |
| GenerateSignatureTimestamp: Whether to generate timestamps in signatures.
For the Java and .NET Editions, if GenerateSignatureTimestamp is True,
a timestamp will be generated and added to all signatures created by the class.
The default value is True. | |
| IncludeHeaders: Tells the class whether to include the headers when encoding the message.If true, the class will include the headers when Sign, Encrypt,
or SignAndEncrypt are called. If false, only the message will be
encoded.
The default value for IncludeHeaders is false. | |
| IncludeInternalHeaders: Tells the class whether or not to include the internal headers when encoding the message.If true, the class will include the internal message part headers when
Sign, Encrypt, or SignAndEncrypt are called. When set to false,
only the message will be encoded.
The default value for IncludeInternalHeaders is true. | |
| ParseInternalHeaders: Tells the class whether or not to parse the message part headers when decrypting a message.If true, the class will parse the internal message part headers when Decrypt,
or DecryptAndVerifySignature are called. These headers will be placed in the
InternalHeaders property. If false, the entire message will be decoded.
The default value for ParseInternalHeaders is true. | |
| RecipientCert: Used to specify the public certificate when using a PEM key to decrypt.When decrypting, the class must search through the Recipient Info collection to find
which encrypted key to use for decryption. Since PEM keys do not contain a serial number
or any additional information about the key itself, the public key associated with this
private key must be supplied.
This configuration may be set to the entire blob of the public certificate the class should use to select the correct recipient encrypted key to use for decryption. | |
| RecipientCertFile: Used to specify the public certificate file when using a PEM key to decrypt.When decrypting, the class must search through the Recipient Info collection to find
which encrypted key to use for decryption. Since PEM keys do not contain a serial number
or any additional information about the key itself, the public key associated with this
private key must be supplied.
This configuration may be set to the file which contains the public certificate the class should use to select the correct recipient encrypted key to use for decryption. | |
| UseCryptoAPI: Whether to use the Microsoft Crypto API for cryptographic message generation.
If UseCryptoAPI is set to true, the class will use the Microsoft Crypto API
to process encrypted and/or signed data. Note that compression will be impossible in this
case.
If set to false (the default), the class will use its internal S/MIME engine. |
Base Configuration Settings
| SelectWaitMillis: The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process. If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20. |
Base Configuration Settings
| CodePage: The system code page used for Unicode to Multibyte translations.
The default code page is the Active Code Page (0).
The following is a list of valid code page identifiers:
