Method Detail

getAlgorithmName

public java.lang.String getAlgorithmName()
Method getAlgorithmName

Specified by:
getAlgorithmName in interface UserDatabase
Returns:
String the algorithm employed by the user of this database for SASL OTP authentication.

getLastHash

public byte[] getLastHash()
                   throws SASLException
Method getLastHash

Specified by:
getLastHash in interface UserDatabase
Returns:
byte[] the lastHash value generated the last time the user of this database performed SASL OTP authentication. The hash value is represented in binary form.
Throws:
SASLException

getLastHashAsString

public java.lang.String getLastHashAsString()
Method getLastHash

Specified by:
getLastHashAsString in interface UserDatabase
Returns:
String the lastHash value generated the last time the user of this database performed SASL OTP authentication. The hash is represented in hexadecimal form.

getSeed

public java.lang.String getSeed()
Method getLastHash

Specified by:
getSeed in interface UserDatabase
Returns:
String the seed used by the user of this database for SASL OTP authentication.

getSequence

public int getSequence()
Method getLastHash

Specified by:
getSequence in interface UserDatabase
Returns:
int the sequence that should be used by the user of this database for their next SASL OTP authentication.

getAuthenticator

public java.lang.String getAuthenticator()
Method getLastHash

Specified by:
getAuthenticator in interface UserDatabase
Returns:
String the last hash value used by the user of this database for SASL OTP authentication.

updateLastHash

public void updateLastHash(java.lang.String hash)
                    throws SASLException
Method updateLastHash

Specified by:
updateLastHash in interface UserDatabase
Parameters:
hash - String is the new hash value to be stored in the user database, for use in comparison the next time they try to authenticate.
Throws:
SASLException - in the event that the update causes an exception to be thrown during the OTP database update.
