Detailed Description

Cryptographic Message Syntax messaging system.

Cryptographic Message Syntax (CMS) "is used to digitally sign, digest, authenticate, or encrypt arbitrary message content. The CMS describes an encapsulation syntax for data protection. It supports digital signatures and encryption. The syntax allows multiple encapsulations; one encapsulation envelope can be nested inside another. Likewise, one party can digitally sign some previously encapsulated data. It also allows arbitrary attributes, such as signing time, to be signed along with the message content, and provides for other attributes such as countersignatures to be associated with a signature." (from RFC3852 "Cryptographic Message Syntax")

Constructor & Destructor Documentation

QCA::CMS::CMS QObject parent = 0,
const QString provider = QString()
[explicit]
 

Standard constructor.

Parameters:
parent the parent object for this object
provider the provider to use, if a specific provider is required


Member Function Documentation

CertificateCollection QCA::CMS::trustedCertificates  )  const
 

Return the trusted certificates set for this object.

CertificateCollection QCA::CMS::untrustedCertificates  )  const
 

Return the untrusted certificates set for this object.

SecureMessageKeyList QCA::CMS::privateKeys  )  const
 

Return the private keys set for this object.

void QCA::CMS::setTrustedCertificates const CertificateCollection trusted  ) 
 

Set the trusted certificates to use for the messages built using this CMS object.

Parameters:
trusted the collection of trusted certificates to use

void QCA::CMS::setUntrustedCertificates const CertificateCollection untrusted  ) 
 

Set the untrusted certificates to use for the messages built using this CMS object.

This function is useful when verifying messages that don't contain the certificates (or intermediate signers) within the CMS blob. In order to verify such messages, you'll have to pass the possible signer certs with this function.

Parameters:
untrusted the collection of untrusted certificates to use

void QCA::CMS::setPrivateKeys const SecureMessageKeyList keys  ) 
 

Set the private keys to use for the messages built using this CMS object.

Keys are required for decrypting and signing (not for encrypting or verifying).

Parameters:
keys the collection of keys to use
Examples:
cmsexample.cpp.
