The S/MIME component implements the S/MIME standard for encryption and decryption with public key cryptography and X.509 digital certificates.

Syntax

TipcSMIME

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:

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

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.

GetSignerCertInfo Method (SMIME Component)

This method gets the signature information for an signed message.

Syntax

void __fastcall GetSignerCertInfo();

Remarks

This method retrieves information about the certificate used to sign the message. This may be called before calling VerifySignature to determine which certificate should be loaded for verification.

When this method is called, the SignerCertInfo event fires once for each signer of the message. Use the parameters of the SignerCertInfo to determine which certificate to specify before calling VerifySignature.

Note: Use of this method is optional. If no certificate is specified before calling VerifySignature, the component will fire the SignerCertInfo and a certificate may be loaded from within the event at that time (if necessary).

Reset Method (SMIME Component)

The value in DetachedSignature is ignored: the component will always generate an attached signature when calling this method. All other properties used by calling the Sign and Encrypt methods are used in the same manner.

Note: The message headers, including the Sender, Recipient(s), and Subject, are not encrypted. If this is sensitive information, consider including these headers in the message body as a MIME entity and providing other headers for the S/MIME wrapper.

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:

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

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.

VerifySignature Method (SMIME Component)

This method verifies the signature of the current message.

Syntax

void __fastcall VerifySignature();

Remarks

This method attempts to verify the signature of the input message. If the message does not have a certificate attached, the component will attempt to verify the signature using the certificate supplied in SignerCert (if any). If no certificate is found, the component raises an exception.

If this method is successful, the SignerCert property will contain the certificate information of the message signer.

Note: This function does not attempt to check the validity of the signing certificate.

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:

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

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.

Error Event (SMIME Component)

Information about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TipcSMIMEErrorEventParams;
typedef void __fastcall (__closure *TipcSMIMEErrorEvent)(System::TObject* Sender, TipcSMIMEErrorEventParams *e);
__property TipcSMIMEErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

RecipientInfo Event (SMIME Component)

This event is fired for each recipient certificate of the encrypted message.

Syntax

typedef struct {
  String Issuer;
  String SerialNumber;
  String SubjectKeyIdentifier;
  String EncryptionAlgorithm;
} TipcSMIMERecipientInfoEventParams;
typedef void __fastcall (__closure *TipcSMIMERecipientInfoEvent)(System::TObject* Sender, TipcSMIMERecipientInfoEventParams *e);
__property TipcSMIMERecipientInfoEvent OnRecipientInfo = { read=FOnRecipientInfo, write=FOnRecipientInfo };

Remarks

When GetRecipientInfo is called on a valid encrypted message, this event will fire once for each recipient certificate that the message has been encrypted for. This may be used to identify the certificate to load.

Issuer is the subject of the issuer certificate.

SerialNumber is the serial number of the encryption certificate.

SubjectKeyIdentifier is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string.

EncryptionAlgorithm is the encryption algorithm used to encrypt the message. Possible values are as follows:

  • "3DES"
  • "DES"
  • "RC2CBC40"
  • "RC2CBC64"
  • "RC2CBC128" or "RC2"
  • "AESCBC128" or "AES"
  • "AESCBC192"
  • "AESCBC256"
  • "AESGCM128" or "AESGCM"
  • "AESGCM192"
  • "AESGCM256"

SignerCertInfo Event (SMIME Component)

This event is fired during verification of the signed message.

Syntax

typedef struct {
  String Issuer;
  String SerialNumber;
  String SubjectKeyIdentifier;
  String CertEncoded;
  DynamicArray<Byte> CertEncodedB;
} TipcSMIMESignerCertInfoEventParams;
typedef void __fastcall (__closure *TipcSMIMESignerCertInfoEvent)(System::TObject* Sender, TipcSMIMESignerCertInfoEventParams *e);
__property TipcSMIMESignerCertInfoEvent OnSignerCertInfo = { 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.

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

ApplyB64Encoding:   Instructs the component to base64 encode the message when signing or encrypting.

This configuration 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 configuration setting may be used only when DetachedSignature is False.

CSP:   The Cryptographic Service Provider.

For the Win32 editions, this configuration setting includes the name of the Cryptographic Service Provider used to provide access to encryption/decryption and signature operations.

Note: This configuration setting may be used only when the UseCryptoAPI is True.

GenerateSignatureTimestamp:   Whether to generate timestamps in signatures.

If GenerateSignatureTimestamp is True, a timestamp will be generated and added to all signatures created by the component.

The default value is True.

IncludeHeaders:   Tells the component whether to include the headers when encoding the message.

If set to True, the component 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 component whether or not to include the internal headers when encoding the message.

If set to True, the component 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.

InputContentTransferEncoding:   Sets the Content-Transfer-Encoding for the signed message.

This configuration setting specifies the Content-Transfer-Encoding header value in signed messages. By default, the component will automatically determine the Content-Transfer-Encoding based on the file extension set in InputFile. This setting may be set to override the determined value or to specify a value if data are read from InputMessage.

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.

InputContentType:   Sets the Content-Type for the signed message.

This configuration setting specifies the Content-Type header value in signed messages. By default, the component will automatically determine the Content-Type based on the file extension set in InputFile. This setting may be set to override the determined value or to specify a value if data are read from InputMessage.

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.

InputMessageEncrypted:   Whether or not the input message is encrypted.

This configuration setting will return True if the input message appears to be encrypted according to the value of InputMessageHeaders.

InputMessageSigned:   Whether or not the input message is signed.

This will return true if the input message appears to be signed according to the value of InputMessageHeaders.

NormalizeCRLF:   Whether or not the component will normalize line endings of the input data to CrLf.

Setting this configuration setting to True will instruct the component to normalize the line endings of the input data to CrLf prior to processing. The default value is False.

OAEPMGF1HashAlgorithm:   The MGF1 hash algorithm used with OAEP.

This configuration setting specifies the MGF1 hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

  • "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.

OAEPParams:   The hex encoded OAEP parameters.

This configuration setting optionally specifies Optimal Asymmetric Encryption Padding (OAEP) parameters to be used when UseOAEP is set to True. The specified value should be hex encoded.

OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

  • "SHA1"
  • "SHA224"
  • "SHA256" (default)
  • "SHA384"
  • "SHA512"
  • "RIPEMD160"
  • "MD2"
  • "MD5"
  • "MD5SHA1"
ParseInternalHeaders:   Tells the component whether or not to parse the message part headers when decrypting a message.

If set to True, the component 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 component must search through the Recipient Information collection to find which encrypted key to use for decryption. Because 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 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.

RecipientCertFile:   Used to specify the public certificate file when using a PEM key to decrypt.

When decrypting, the component must search through the Recipient Information collection to find which encrypted key to use for decryption. Because 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 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.

RecipientInfoType:   The type of signer information to include in the signed message.

This configuration setting specifies which type of information about the recipient's encryption certificate is included in the encrypted message. Possible values are as follows:

  • 0 (issuerAndSerialNumber - default)
  • 1 (subjectKeyIdentifier)

Note: When subjectKeyIdentifier is selected, the recipient's encryption certificate must contain the subjectKeyIdentifier extension.

SignerInfoType:   The type of signer information to include in the signed message.

This configuration setting specifies which type of information about the signer certificate is included in the signed message. Possible values are as follows:

  • 0 (issuerAndSerialNumber - default)
  • 1 (subjectKeyIdentifier)

Note: When subjectKeyIdentifier is selected, the signing certificate must contain the subjectKeyIdentifier extension.

UseAlgorithmOIDs:   Whether OIDs are used when providing information about the algorithms.

This configuration setting controls whether the EncryptionAlgorithm parameter of the RecipientInfo event is populated with the name of the algorithm, such as 3DES or the corresponding OID such as 1.2.840.113549.3.7.

The default value is False, and the name of the algorithm is used. Set this to True to use the object identifiers instead.

UseCryptoAPI:   Whether to use the Microsoft Crypto API for cryptographic message generation.

If UseCryptoAPI is set to True, the component will use the Microsoft Crypto API to process encrypted and/or signed data.

Note: Compression will be impossible in this case.

If set to False (the default), the component will use its internal S/MIME engine.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).
