Member Function Documentation

void cleanup (   )  [virtual]

This function performs internal cleanup and will be called after a failed handshake attempt. Implements TLSBase. Definition at line 114 of file tlsopenssl.cpp.

int decrypt (  const std::string &  data  )  [virtual]

Use this function to feed encrypted data or received handshake data to the encryption implementation. Handshake data will be eaten, unencrypted data will be pushed to the TLSHandler's handleDecryptedData() function. Parameters: data  The data to decrypt. Returns: The number of bytes used from the input. Implements TLSBase. Definition at line 79 of file tlsopenssl.cpp.

bool encrypt (  const std::string &  data  )  [virtual]

Use this function to feed unencrypted data to the encryption implementation. The encrypted result will be pushed to the TLSHandler's handleEncryptedData() function. Parameters: data  The data to encrypt. Returns: Whether or not the data was used successfully. Implements TLSBase. Definition at line 65 of file tlsopenssl.cpp.

bool handshake (   )  [virtual]

This functiopn performs the TLS handshake. Handshake data from the server side should be fed in using decrypt(). Handshake data that is to be sent to the other side is pushed through TLSBase's handleEncryptedData(). Returns: True if the handshake was successful or if more input is needed, false if the handshake failed. Implements TLSBase. Definition at line 200 of file tlsopenssl.cpp.

void setCACerts (  const StringList &  cacerts  )  [virtual]

Use this function to set a number of trusted root CA certificates which shall be used to verify a servers certificate. Parameters: cacerts  A list of absolute paths to CA root certificate files in PEM format. Implements TLSBase. Definition at line 93 of file tlsopenssl.cpp.

void setClientCert (  const std::string &  clientKey, const std::string &  clientCerts )  [virtual]

Use this function to set the user's certificate and private key. The certificate will be presented to the server upon request and can be used for SASL EXTERNAL authentication. The user's certificate file should be a bundle of more than one certificate in PEM format. The first one in the file should be the user's certificate, each cert following that one should have signed the previous one. Note: These certificates are not necessarily the same as those used to verify the server's certificate. Parameters: clientKey  The absolute path to the user's private key in PEM format. clientCerts  A path to a certificate bundle in PEM format. Implements TLSBase. Definition at line 102 of file tlsopenssl.cpp.
