SMIME Class

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

Syntax

SMIME

Remarks

The S/MIME class implements the S/MIME V3 standard for encryption and decryption using Public Key Cryptography Standards (PKCS). In addition, the class can be used to both generate and verify RSA digital signatures. Using this class 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 class 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:

  • 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 class can also generate PKCS #7 formatted detached digital signatures and envelopes by specifying DetachedSignature.

Encrypting

To encrypt a message with the class 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 class 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 class 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 class 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 class 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.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the RecipientCertStore and set RecipientCertStorePassword to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

The RecipientCertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the RecipientCertCount property.

This property is not available at design time.

int ipworksencrypt_smime_setsignercertstoretype(void* lpObj, int iSignerCertStoreType);
int GetSignerCertStoreType();
int SetSignerCertStoreType(int iSignerCertStoreType);

Default Value

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.
6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)The certificate store is the name of a PKCS7 file containing certificates.
12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS7 format.
13 (cstSSHPublicKeyFile)The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.
22 (cstBCFKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SignerCertStore and set SignerCertStorePassword to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

char* ipworksencrypt_smime_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These 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.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

This event is fired during verification of the signed message.

Syntax

ANSI (Cross Platform)
virtual int FireSignerCertInfo(SMIMESignerCertInfoEventParams *e);
typedef struct {
const char *Issuer;
const char *SerialNumber;
const char *SubjectKeyIdentifier;
const char *CertEncoded; int lenCertEncoded; int reserved; } SMIMESignerCertInfoEventParams;
Unicode (Windows) virtual INT FireSignerCertInfo(SMIMESignerCertInfoEventParams *e);
typedef struct {
LPCWSTR Issuer;
LPCWSTR SerialNumber;
LPCWSTR SubjectKeyIdentifier;
LPCSTR CertEncoded; INT lenCertEncoded; INT reserved; } SMIMESignerCertInfoEventParams;
#define EID_SMIME_SIGNERCERTINFO 3

virtual INT IPWORKSENCRYPT_CALL FireSignerCertInfo(LPSTR &lpszIssuer, LPSTR &lpszSerialNumber, LPSTR &lpszSubjectKeyIdentifier, LPSTR &lpCertEncoded, INT &lenCertEncoded);
class SMIMESignerCertInfoEventParams {
public:
  const QString &Issuer();

  const QString &SerialNumber();

  const QString &SubjectKeyIdentifier();

  const QByteArray &CertEncoded();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void SignerCertInfo(SMIMESignerCertInfoEventParams *e);
// Or, subclass SMIME and override this emitter function. virtual int FireSignerCertInfo(SMIMESignerCertInfoEventParams *e) {...}

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 class 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 Class)

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 Config Settings

ApplyB64Encoding:   Instructs the class 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 class.

The default value is True.

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

If set to 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 set to 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.

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 class 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 class 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 class will normalize line endings of the input data to CrLf.

Setting this configuration setting to True will instruct the class 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 class whether or not to parse the message part headers when decrypting a message.

If set to 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 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 class 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 class 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 class 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 class 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 class 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).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

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.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to true tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.

Trappable Errors (SMIME Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
