Method Detail

setVerifyServerResponse

public static void setVerifyServerResponse(boolean verifyServerResponse)

authenticateInternal

protected void authenticateInternal(CallbackHandler cbh)

Specified by:

authenticateInternal in class SASLMechanism

getAuthenticationText

protected byte[] getAuthenticationText()

Description copied from class: SASLMechanism

Should return the initial response of the SASL mechanism. The returned byte array will be send base64 encoded to the server. SASL mechanism are free to return null or an empty array here.

Specified by:

getAuthenticationText in class SASLMechanism

Returns:

the initial response or null

getName

public String getName()

Description copied from class: SASLMechanism

Returns the common name of the SASL mechanism. E.g.: PLAIN, DIGEST-MD5 or GSSAPI.

Specified by:

getName in class SASLMechanism

Returns:

the common name of the SASL mechanism.

getPriority

public int getPriority()

Description copied from class: SASLMechanism

Get the priority of this SASL mechanism. Lower values mean higher priority.

Specified by:

getPriority in class SASLMechanism

Returns:

the priority of this SASL mechanism.

newInstance

public SASLDigestMD5Mechanism newInstance()

Specified by:

newInstance in class SASLMechanism

authzidSupported

public boolean authzidSupported()

Overrides:

authzidSupported in class SASLMechanism

checkIfSuccessfulOrThrow

public void checkIfSuccessfulOrThrow()
                              throws SmackException.SmackSaslException

Specified by:

checkIfSuccessfulOrThrow in class SASLMechanism

Throws:

SmackException.SmackSaslException

evaluateChallenge

protected byte[] evaluateChallenge(byte[] challenge)
                            throws SmackException.SmackSaslException

Description copied from class: SASLMechanism

Evaluate the SASL challenge.

Overrides:

evaluateChallenge in class SASLMechanism

Parameters:

challenge - challenge to evaluate.

Returns:

null.

Throws:

SmackException.SmackSaslException - If a SASL related error occurs.

quoteBackslash

public static String quoteBackslash(String string)

Quote the backslash in the given String. Replaces all occurrences of "\" with "\\".

According to RFC 2831 § 7.2 a quoted-string consists either of qdtext or quoted-pair. And since quoted-pair is a backslash followed by a char, every backslash in qdtext must be quoted, since it otherwise would be treated as qdtext.
