EKResolverlocates an EncryptedKey pertaining to the EncryptedData

Member Function Documentation

xercesc::DOMDocumentFragment* xmlencryption::Decrypter::decryptData ( const EncryptedData &  encryptedData,
XSECCryptoKey *  key 
)

Decrypts the supplied information using the supplied key, and returns the resulting as a DOM fragment owned by the document associated with the marshalled EncryptedData object.

Note that the DOM nodes will be invalidated once that document is released. The caller should therefore process the DOM fragment as required and drop all references to it before that happens. The usual approach should be to unmarshall the DOM and then release it, or the DOM can also be imported into a separately owned document.

Parameters
encryptedDatathe data to decrypt
keythe decryption key to use (it will not be freed internally)
Returns
the decrypted DOM fragment
xercesc::DOMDocumentFragment* xmlencryption::Decrypter::decryptData ( const EncryptedData &  encryptedData,
const XMLCh *  recipient = 0 
)

Decrypts the supplied information and returns the resulting as a DOM fragment owned by the document associated with the marshalled EncryptedData object.

Note that the DOM nodes will be invalidated once that document is released. The caller should therefore process the DOM fragment as required and drop all references to it before that happens. The usual approach should be to unmarshall the DOM and then release it, or the DOM can also be imported into a separately owned document.

Parameters
encryptedDatathe data to decrypt
recipientidentifier of decrypting entity for use in identifying multi-cast keys
Returns
the decrypted DOM fragment
void xmlencryption::Decrypter::decryptData ( std::ostream &  out,
const EncryptedData &  encryptedData,
XSECCryptoKey *  key 
)

Decrypts the supplied information to an output stream.

Parameters
outoutput stream to receive the decrypted data
encryptedDatathe data to decrypt
keythe decryption key to use (it will not be freed internally)
void xmlencryption::Decrypter::decryptData ( std::ostream &  out,
const EncryptedData &  encryptedData,
const XMLCh *  recipient = 0 
)

Decrypts the supplied information to an output stream.

Parameters
outoutput stream to receive the decrypted data
encryptedDatathe data to decrypt
recipientidentifier of decrypting entity for use in identifying multi-cast keys
XSECCryptoKey* xmlencryption::Decrypter::decryptKey ( const EncryptedKey &  encryptedKey,
const XMLCh *  algorithm 
)

Decrypts the supplied information and returns the resulting key.

The caller is responsible for deleting the key. The algorithm of the key must be supplied by the caller based on knowledge of the associated EncryptedData information.

Parameters
encryptedKeythe encrypted/wrapped key to decrypt
algorithmthe algorithm associated with the decrypted key
Returns
the decrypted key
void xmlencryption::Decrypter::setEncryptedKeyResolver ( const EncryptedKeyResolver EKResolver)

Replace the current EncryptedKeyResolver interface, if any, with a new one.

Parameters
EKResolverthe EncryptedKeyResolver to attach
void xmlencryption::Decrypter::setKEKResolver ( const xmltooling::CredentialResolver resolver,
xmltooling::CredentialCriteria criteria 
)

Replace the current CredentialResolver interface, if any, with a new one.

Parameters
resolverthe locked CredentialResolver to attach, or nullptr to clear
criteriaoptional external criteria to use with resolver
