Method Detail

checkSemantics

void checkSemantics(DirectiveList dirList)
              throws SaslException

Checks the semantics of the directives in the directive list as parsed from the digest challenge byte array.

Parameters:

dirList - the list of directives parsed from the digest challenge

Throws:

SaslException - If a semantic error occurs

handleNonce

void handleNonce(ParsedDirective pd)
           throws SaslException

This function implements the semenatics of the nonce directive.

Parameters:

pd - ParsedDirective

SaslException - If an error occurs dur to too many charset directives or Invalid character encoding directive

handleAlgorithm

void handleAlgorithm(ParsedDirective pd)
               throws SaslException

This function implements the semenatics of the charset directive. the value is defined as: 1*DIGIT

Parameters:
