CMS Control
Properties Methods Events Config Settings Errors
The CMS control is used to digitally sign, encrypt, verify, and decrypt data.
Syntax
CMS
Remarks
The CMS control implements the Cryptographic Message Syntax and allow for various cryptographic operations to be performed on data including:
The control can generate and consume message in a variety of formats including PEM, DER (Binary), and SMIME. The EncryptionAlgorithm and SignatureHashAlgorithm are fully configurable and support a variety of industry standard encryption and hash algorithms.
The control supports additional functionality such as Compression, OAEP, and PSS. The GetRecipientInfo and GetSignerCertInfo methods as well as the RecipientInfo and SignerCertInfo events allow for a dynamic and flexible approach to message processing. Certificate may be loaded ahead of time or as-needed from the events.
Signing Notes
Sign digitally signs the input data with the the specified certificate(s). Certificates are specified by calling AddCertificate or setting the Certificates property.OutputFormat specifies the encoding of the output message. Valid values are PEM, DER, and SMIME. IncludeCertificates specifies whether the public certificate is included in the signed message. Additional settings allow further configuration. The following properties are applicable when calling this method:
- Certificates (required)
- DetachedSignature
- EnableCompression

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 control 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 control 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:
- OutputFile
- OutputMessage: The output data is written to this property if no other destination is specified.

AddCertificate Method (CMS Control)
Used to add certificates for signing.
Syntax
cmscontrol.AddCertificate CertStoreType, CertStore, CertStorePassword, CertSubject
Remarks
This method adds a signing certificate. Signing certificates may be added using this method or by adding a certificate directly to Certificates.
The added certificate(s) will be used to sign the message when Sign is called.
CertStoreType specifies the type of certificate store. The control supports both public and private keys in a variety of formats. When the cstAuto value is used the control 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). |

| 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 control. 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 and set to the PIN. Code Example: SSH Authentication with Security Key
|

CertEncoded must contain the PEM or Base64 encoded public certificate.
Config Method (CMS Control)
Sets or retrieves a configuration setting.
Syntax
cmscontrol.Config ConfigurationString
Remarks
Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, 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.
Decrypt Method (CMS Control)
Decrypts the current message.
Syntax
cmscontrol.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 control 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:
- OutputFile
- OutputMessage: The output data is written to this property if no other destination is specified.

DecryptAndVerifySignature Method (CMS Control)
Decrypts and verifies the signature of the current message.
Syntax
cmscontrol.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 control 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 control 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:
- OutputFile
- OutputMessage: The output data is written to this property if no other destination is specified.

Remarks
During verification, this event will be raised while parsing the signer's certificate information. The parameters which are populated depends on the options used when the message was originally signed. This information may be used to select the correct certificate for SignerCerts in order 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 control 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.
Config Settings (CMS Control)
The control 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 control, access to these internal properties is provided through the Config method.CMS Config Settings | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
