Detailed Description

This is the common base class for (stream) encryption using GnuTLS.

You should not need to use this class directly.

Constructor & Destructor Documentation

◆ GnuTLSBase()

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

Constructor.

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

Definition at line 27 of file tlsgnutlsbase.cpp.

◆ ~GnuTLSBase()

~GnuTLSBase ( )
virtual

Virtual destructor.

Definition at line 33 of file tlsgnutlsbase.cpp.

Member Function Documentation

◆ channelBinding()

const std::string channelBinding ( ) const
virtual

Returns the channel binding data for the established connection.

Returns
The channel binding data, if any, or the empty string.

Reimplemented from TLSBase.

Definition at line 159 of file tlsgnutlsbase.cpp.

◆ cleanup()

void cleanup ( )
virtual

This function performs internal cleanup and will be called after a failed handshake attempt.

Implements TLSBase.

Reimplemented in GnuTLSServerAnon, GnuTLSServer, GnuTLSClientAnon, and GnuTLSClient.

Definition at line 98 of file tlsgnutlsbase.cpp.

◆ decrypt()

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 64 of file tlsgnutlsbase.cpp.

◆ encrypt()

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 45 of file tlsgnutlsbase.cpp.

◆ handshake()

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 122 of file tlsgnutlsbase.cpp.

◆ hasChannelBinding()

bool hasChannelBinding ( ) const
virtual

This function indicates whether the underlying TLS implementation supports channel binding (used in e.g. SASL SCRAM-SHA-1-PLUS).

Returns
True if channel binding is supported, false otherwise.

Reimplemented from TLSBase.

Definition at line 150 of file tlsgnutlsbase.cpp.

◆ setCACerts()

virtual void setCACerts ( const StringList cacerts)
inlinevirtual

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.

Reimplemented in GnuTLSClient.

Definition at line 72 of file tlsgnutlsbase.h.

◆ setClientCert()

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

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.

Reimplemented in GnuTLSClient.

Definition at line 75 of file tlsgnutlsbase.h.
