Detailed Description

Encryption and Decryption class for Message types. Used with TipcMt::setEncryptObj(), TipcMt::setDecryptObj(), and triggered whenever TipcMsg::encrypt() or TipcMsg::decrypt() is called. Note that not only encryption (for data scrambling) can be done, but also data compression. The message header is left intact with this mechanism.

Member Typedef Documentation

typedef void(TipcMtEncrypt::* SmartSockets::TipcMtEncrypt::Handler)(void*& data, int4& dataSize, const void* key, int4 keySize)

Method signature for encryption and decryption methods. Warning: If the data needs to grow (e.g. be reallocated) then the new char[<size>]; operator should be used. Parameters: data  the user data portion of the message to be encrypted/decrypted serialized in a binary blob. This parameter is also used to return the encrypted/decrypted data. dataSize  the number of bytes in the user data binary blob. This parameter is also used to return the size of the encrypted/decrypted data. key  the key to encrypt/decrypt the data set using the TipcMt::setKey() method. keySize  the number of bytes in the key.

Member Function Documentation

virtual void SmartSockets::TipcMtEncrypt::decrypt (  void *&    data, int4 &    dataSize, const void *    key, int4    keySize )  throw (TipcException) [virtual]

Default implementation for an decryption method that doesn't do anything. Parameters: data  the user data portion of the message to be encrypted serialized in a binary blob. This parameter is also used to return the encrypted data. If the data needs to grow (e.g. be reallocated) then the new char[<size>]; operator should be used. dataSize  the number of bytes in the user data binary blob. This parameter is also used to return the size of the encrypted data. key  the key to encrypt the data set using the TipcMt::setKey() method. keySize  the number of bytes in the key.

virtual void SmartSockets::TipcMtEncrypt::encrypt (  void *&    data, int4 &    dataSize, const void *    key, int4    keySize )  throw (TipcException) [virtual]

Default implementation for an encryption method that doesn't do anything. Parameters: data  the user data portion of the message to be encrypted serialized in a binary blob. This parameter is also used to return the encrypted data. dataSize  the number of bytes in the user data binary blob. This parameter is also used to return the size of the encrypted data. If the data needs to grow (e.g. be reallocated) then the new char[<size>]; operator should be used. key  the key to encrypt the data set using the TipcMt::setKey() method. keySize  the number of bytes in the key.

Handler SmartSockets::TipcMtEncrypt::getDecryptHandler (    )

Gets the current decrypt handler method.

Handler SmartSockets::TipcMtEncrypt::getEncryptHandler (    )

Gets the current encrypt handler method.

void SmartSockets::TipcMtEncrypt::setDecryptHandler (  Handler    decryptMethod )

Sets the current decrypt handler method; if this is not called, the default method decrypt() is called. Parameters: encryptMethod  a method conforming to the TipcMtEncrypt::Handler.

void SmartSockets::TipcMtEncrypt::setEncryptHandler (  Handler    encryptMethod )

Sets the current encrypt handler method; if this is not called, the default method encrypt() is called.
