Constructor & Destructor Documentation

OpenSSLBase ( TLSHandler th,
const std::string &  server = EmptyString 
)

Constructor.

Parameters:
thThe TLSHandler to handle TLS-related events.
serverThe server to use in certificate verification.

~OpenSSLBase ( ) [virtual]

Virtual destructor.

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 146 of file tlsopensslbase.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:
dataThe data to decrypt.
Returns:
The number of bytes used from the input.

Implements TLSBase.

Definition at line 100 of file tlsopensslbase.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:
dataThe data to encrypt.
Returns:
Whether or not the data was used successfully.

Implements TLSBase.

Definition at line 86 of file tlsopensslbase.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 238 of file tlsopensslbase.cpp.

bool init ( const std::string &  clientKey = EmptyString,
const std::string &  clientCerts = EmptyString,
const StringList cacerts = StringList() 
) [virtual]

Initializes the TLS module. This function must be called (and execute successfully) before the module can be used.

Parameters:
clientKeyThe absolute path to the user's private key in PEM format.
clientCertsA path to a certificate bundle in PEM format.
cacertsA list of absolute paths to CA root certificate files in PEM format.
Returns:
False if initialization failed, true otherwise.
Since:
1.0

Implements TLSBase.

Definition at line 46 of file tlsopensslbase.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:
cacertsA list of absolute paths to CA root certificate files in PEM format.

Implements TLSBase.

Definition at line 114 of file tlsopensslbase.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:
clientKeyThe absolute path to the user's private key in PEM format.
clientCertsA path to a certificate bundle in PEM format.

Implements TLSBase.
