SMIME Component
Properties Methods Events Config Settings Errors
The S/MIME component implements the S/MIME standard for encryption and decryption with public key cryptography and X.509 digital certificates.
Syntax
TipmSMIME
Remarks
The S/MIME component implements the S/MIME V3 standard for encryption and decryption using Public Key Cryptography Standards (PKCS). In addition, the component can be used to both generate and verify RSA digital signatures. Using this component for decrypting or signing requires a valid digital certificate with a private key.
Before performing an operation the input and output values should be specified.
Input and Output Properties
The component will determine the source and destination of the input and output based on which properties are set.
The order in which the input properties are checked is as follows:
- SetInputStream
- InputFile
- InputMessage
When a valid source is found the search stops. The order in which the output properties are checked is as follows:
- SetOutputStream
- OutputFile
- OutputMessage: The output data is written to this property if no other destination is specified.
When using streams you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.
The headers of the input message (if any) will be read from InputMessageHeaders or InputMessageHeadersString.
The headers of the resulting message will be available in the OutputMessageHeaders and OutputMessageHeadersString properties.
Signing
To sign the current data included in the input message with a certificate, the Certificate property must be set to a valid Certificate object for the signing certificate. The IncludeCertificate and DetachedSignature properties allow you to specify additional details about the signing process. By setting IncludeCertificate to True, digital certificates can be encoded and included in message signature when signing the document. Including a certificate is the preferred method of building signed messages. In addition the S/MIME component can also generate PKCS #7 formatted detached digital signatures and envelopes by specifying DetachedSignature.
Encrypting
To encrypt a message with the component in a PKCS envelope, you must first specify the Certificate for each recipient in the RecipientCerts properties to encrypt the message with. You can easily add these with the AddRecipientCert method. Once you have done this you can call the Encrypt method to encrypt the message with the recipient certificates.
In addition, the component allows you to sign and encrypt simultaneously with the SignAndEncrypt method. You must set all of the properties needed for both Sign and Encrypt
The result of the encrypted or signed data will be replaced in the OutputMessage property and the OutputMessageHeaders property will be filled with the appropriate mime headers if applicable.
Decrypting
Decrypting PKCS envelopes is handled with the Decrypt method. When this method is called, the component will attempt to find an appropriate certificate in the Certificate property that matches the encrypting certificate. If it cannot find an appropriate certificate, an exception will be thrown and the message will not be decrypted.
Verifying Signatures
In addition, the S/MIME component can be used to verify signatures included in signed messages or documents. After specifying the input, VerifySignature can then be used to verify the signature. If the message does not have a certificate attached, more then likely an exception will be thrown and the component will not be able to verify the signature. If VerifySignature is successful, the SignerCert and SignerCertChain properties will be filled with the certificate information of the message signer. This information can be used to verify the signing certificates.
Similar to SignAndEncrypt, DecryptAndVerifySignature can be used to both decrypt and verify the message in Message.

SignerCertInfo Event (SMIME Component)
This event is fired during verification of the signed message.
Syntax
type TSignerCertInfoEvent = procedure ( Sender: TObject; const Issuer: String; const SerialNumber: String; const SubjectKeyIdentifier: String; CertEncoded: String; CertEncodedB: TBytes ) of Object;
property OnSignerCertInfo: TSignerCertInfoEvent read FOnSignerCertInfo write FOnSignerCertInfo;
Remarks
During verification, this event will be raised while parsing the signer's certificate information. The parameters that are populated depend on the options used when the message was originally signed. This information may be used to select the correct certificate for SignerCert to verify the signature. The following parameters may be populated:
Issuer specifies the subject of the issuer of the certificate used to sign the message.
SerialNumber is the serial number of the certificate used to sign the message.
SubjectKeyIdentifier is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string.
CertEncoded is the PEM (Base64 encoded) public certificate needed to verify the signature.
Note: When this value is present, the component will automatically use this value to perform signature verification.
The SignerCert property may be set from within this event. In this manner, the decision of which signer certificate to load may be delayed until the parameters of this event are inspected and the correct certificate can be located and loaded.
Header Type
This is an HTTP header as it is received from the server.
Remarks
When a header is received through a Header event, it is parsed into a Header type. This type contains a Field, and its corresponding Value.
Fields
Field
String
Default Value: ""
This property contains the name of the HTTP Header (this is the same case as it is delivered).
Value
String
Default Value: ""
This property contains the Header contents.
Constructors
constructor Create();
constructor Create(valField: String; valValue: String);
Config Settings (SMIME Component)
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.SMIME Config Settings
Note: When signing, this configuration setting may be used only when DetachedSignature is False.
Note: This configuration setting may be used only when the UseCryptoAPI is True.
The default value is True.
The default value for IncludeHeaders is False.
The default value for IncludeInternalHeaders is True.
If no value is specified and a value cannot be automatically determined, the default value 7bit will be used.
Note: This setting is applicable only when calling Sign or SignAndEncrypt and DetachedSignature is True.
If no value is specified and a value cannot be automatically determined, the default value text/plain; charset="iso-8859-1" will be used.
Note: This setting is applicable only when calling Sign or SignAndEncrypt and DetachedSignature is True.
- "SHA1"
- "SHA224"
- "SHA256" (default)
- "SHA384"
- "SHA512"
- "RIPEMD160"
- "MD2"
- "MD5"
- "MD5SHA1"
Note: This setting is not applicable when UseFIPSCompliantAPI is set to True or when the private key of the signing certificate is not exportable since the underlying system implementation does not support separate OAEPRSAHashAlgorithm and OAEPMGF1HashAlgorithm values. In this case the OAEPRSAHashAlgorithm is also used for MGF1.
- "SHA1"
- "SHA224"
- "SHA256" (default)
- "SHA384"
- "SHA512"
- "RIPEMD160"
- "MD2"
- "MD5"
- "MD5SHA1"
The default value for ParseInternalHeaders is True.
This configuration setting may be set to the entire blob of the public certificate the component should use to select the correct recipient-encrypted key for decryption.
This configuration setting may be set to the file that contains the public certificate the component should use to select the correct recipient-encrypted key for decryption.
- 0 (issuerAndSerialNumber - default)
- 1 (subjectKeyIdentifier)
Note: When subjectKeyIdentifier is selected, the recipient's encryption certificate must contain the subjectKeyIdentifier extension.
- 0 (issuerAndSerialNumber - default)
- 1 (subjectKeyIdentifier)
Note: When subjectKeyIdentifier is selected, the signing certificate must contain the subjectKeyIdentifier extension.
The default value is False, and the name of the algorithm is used. Set this to True to use the object identifiers instead.
Note: Compression will be impossible in this case.
If set to False (the default), the component will use its internal S/MIME engine.
