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

CMS()

QCA::CMS::CMS ( QObject * parent = nullptr, 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

privateKeys()

SecureMessageKeyList QCA::CMS::privateKeys

(

)

const

Return the private keys set for this object.

setPrivateKeys()

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

setTrustedCertificates()

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

setUntrustedCertificates()

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

trustedCertificates()

CertificateCollection QCA::CMS::trustedCertificates

(

)

const

Return the trusted certificates set for this object.

untrustedCertificates()

CertificateCollection QCA::CMS::untrustedCertificates

(

)

const

Return the untrusted certificates set for this object.
