Member Enumeration Documentation

enum Type

Supported TLS types.

Enumerator:

VerifyingClient	TLS client, verifying, available for all TLS implementations.
AnonymousClient	Anonymous TLS client (non-verifying), available with GnuTLS.
VerifyingServer	TLS server, verifying, currently not available.
AnonymousServer	Anonymous TLS server (non-verifying), available with GnuTLS.

Definition at line 37 of file tlsdefault.h.

Constructor & Destructor Documentation

TLSDefault	(	TLSHandler *	th,
		const std::string	server,
		Type	type = VerifyingClient
	)

Constructs a new TLS wrapper.

Parameters

th	The TLSHandler to handle TLS-related events.
server	The server to use in certificate verification.
type	What you want to use this TLS object for.

Definition at line 41 of file tlsdefault.cpp.

~TLSDefault ( )

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 108 of file tlsdefault.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 100 of file tlsdefault.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 92 of file tlsdefault.cpp.

const CertInfo & fetchTLSInfo ( ) const

virtual

This function is used to retrieve certificate and connection info of a encrypted connection.

Returns

Certificate information.

Reimplemented from TLSBase.

Definition at line 136 of file tlsdefault.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 114 of file tlsdefault.cpp.

bool isSecure ( ) const

virtual

Returns the state of the encryption.

Returns

The state of the encryption.

Reimplemented from TLSBase.

Definition at line 122 of file tlsdefault.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 130 of file tlsdefault.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 144 of file tlsdefault.cpp.

int types ( )

static

Returns an ORed list of supported TLS types.

Returns

ORed TLSDefault::type members.
