Signature Verification Notes
VerifySignature verifies the signature of the input message.In order to perform signature verification the public signer's certificate must be present or explicitly specified. In many cases the certificate itself is included in the input message and a certificate does not need to explicitly be set. If a certificate does need to be set for signature verification the certificate may be specified by calling AddRecipientCert or setting RecipientCerts.
When this method is called the SignerCertInfo event fires once for each signature on the message. This event provides details about the signer certificate, as well as the signer certificate itself (if present). The information provided via SignerCertInfo may be used to load an appropriate certificate for verification from within the event. If the CertEncoded parameter of SignerCertInfo is populated the certificate required for verification is already present in the message.
The following property are applicable when calling this method:
If the input message is a detached signature, the original data that was signed must be specified in DetachedSignatureData. In addition the DetachedSignature property must be set to True to instruct the class to treat the input message as a detached signature.
If the input message is compressed EnableCompression must be set to True before calling this method.
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.

Default Value
""
Remarks
This is the subject of the certificate used for client authentication.
This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.
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.
| Field | Meaning |
| CN | Common Name. This is commonly a host name like www.server.com. |

char* ipworksencrypt_cms_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.
Decrypt Method (CMS Class)
Decrypts the current message.
Syntax
ANSI (Cross Platform) int Decrypt(); Unicode (Windows) INT Decrypt();
int ipworksencrypt_cms_decrypt(void* lpObj);
int Decrypt();
Remarks
Decrypt decrypts the input data with the specified certificate. Certificates are specified by calling AddCertificate or setting the Certificates property.
If the certificate used to encrypt the message is not known ahead of time GetRecipientInfo may be called prior to calling Decrypt to obtain information about the recipient (the entity the for which the message was encrypted). If GetRecipientInfo is called, the RecipientInfo event is fired with information about the recipient which may be used to load an appropriate decryption certificate.
The following properties are applicable when calling this method:
- Certificates (Required)
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.

DecryptAndVerifySignature Method (CMS Class)
Decrypts and verifies the signature of the current message.
Syntax
ANSI (Cross Platform) int DecryptAndVerifySignature(); Unicode (Windows) INT DecryptAndVerifySignature();
int ipworksencrypt_cms_decryptandverifysignature(void* lpObj);
int DecryptAndVerifySignature();
Remarks
This method decrypts the input data and verifies the signature. Decryption certificates are specified by calling AddCertificate or setting the Certificates property. Certificates used to verify the signature will be taken from the message itself if included, or from the SignerCerts property.
If the certificate used to encrypt the message is not known ahead of time GetRecipientInfo may be called prior to calling Decrypt to obtain information about the recipient (the entity the for which the message was encrypted). If GetRecipientInfo is called, the RecipientInfo event is fired with information about the recipient which may be used to load an appropriate decryption certificate.
In order to perform signature verification the public signer's certificate must be present or explicitly specified. In many cases the certificate itself is included in the input message and a certificate does not need to explicitly be set. If a certificate does need to be set for signature verification the certificate may be specified by calling AddRecipientCert or setting RecipientCerts.
When this method is called the SignerCertInfo event fires once for each signature on the message. This event provides details about the signer certificate, as well as the signer certificate itself (if present). The information provided via SignerCertInfo may be used to load an appropriate certificate for verification from within the event. If the CertEncoded parameter of SignerCertInfo is populated the certificate required for verification is already present in the message.
The following properties are applicable when calling this method:
- Certificates (Required)
- DetachedSignature
- DetachedSignatureData
- EnableCompression
- SignerCerts
If the input message is a detached signature, the original data that was signed must be specified in DetachedSignatureData. In addition the DetachedSignature property must be set to True to instruct the class to treat the input message as a detached signature.
If the input message is compressed EnableCompression must be set to True before calling this method.
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.
Error Handling (C++)
This method returns a 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. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

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 SignerCerts 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.
IPWorksEncryptStream Type
Syntax
IPWorksEncryptStream (declared in ipworksencrypt.h)
Remarks
The CMS class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the IPWorksEncryptStream interface and pass the CMS class an instance of that concrete class.
When implementing the IPWorksEncryptStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.
Properties | |
| CanRead |
Whether the stream supports reading.
bool CanRead() { return true; }
|
| CanSeek |
Whether the stream supports seeking.
bool CanSeek() { return true; }
|
| CanWrite |
Whether the stream supports writing.
bool CanWrite() { return true; }
|
| Length |
Gets the length of the stream, in bytes.
int64 GetLength() = 0; |
Methods | |
| Close |
Closes the stream, releasing all resources currently allocated for it.
void Close() {}
This method is called automatically when an IPWorksEncryptStream object is deleted. |
| Flush |
Forces all data held by the stream's buffers to be written out to storage.
int Flush() { return 0; }
Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0. |
| Read |
Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read.
int Read(void* buffer, int count) = 0; Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream. Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed. |
| Seek |
Sets the current position within the stream based on a particular point of origin.
int64 Seek(int64 offset, int seekOrigin) = 0; Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are:
Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged. Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported. |
| Write |
Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written.
int Write(const void* buffer, int count) = 0; Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream. Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed. |
Config Settings (CMS 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.CMS Config Settings
The default value is 1.2.840.113549.1.7.1 which is the OID for id-data.
NOTE: This config may only be used when the UseCryptoAPI is true.
The default value is True.
The default value for IncludeHeaders is true.
Note: This setting is only applicable to when OutputFormat is set to SMIME.
When set to False, only the message will be processed, MIME part headers will not be generated or stripped.
The default value for IncludeInternalHeaders is False.
Note: This setting is only applicable to when OutputFormat is set to SMIME.
If no value is specified and a value cannot be automatically determined the default value 7bit will be used.
Note: This setting is only applicable when OutputFormat is set to SMIME and 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 only applicable when OutputFormat is set to SMIME and when calling Sign or SignAndEncrypt and DetachedSignature is True.
| 0 (None) | No events are logged. |
| 1 (Info - default) | Informational events are logged. |
| 2 (Verbose) | Detailed data is logged. |
| 3 (Debug) | Debug data is logged. |
- "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"
- 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.

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 (CMS 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.
