Constructor Detail

CryptedSimpleCredentials

public CryptedSimpleCredentials(SimpleCredentials credentials)
                         throws NoSuchAlgorithmException,
                                UnsupportedEncodingException

Build a new instance of CryptedSimpleCredentials from the given SimpleCredentials and create the crypted password field using the default digest.

Parameters:

credentials -

Throws:

NoSuchAlgorithmException

UnsupportedEncodingException

CryptedSimpleCredentials

public CryptedSimpleCredentials(String userId,
                                String cryptedPassword)
                         throws NoSuchAlgorithmException,
                                UnsupportedEncodingException

Create a new instanceof CryptedSimpleCredentials from the given userId and cryptedPassword strings. In contrast to CryptedSimpleCredentials(SimpleCredentials) that expects the password to be plain text this constructor expects the password to be already crypted. However, it performs a simple validation and calls Text.digest(String, byte[]) using the default digest in case the given password is found to be plain text.

Parameters:

userId -

cryptedPassword -

Throws:

NoSuchAlgorithmException

UnsupportedEncodingException

Method Detail

getUserID

public String getUserID()

getAttribute

public Object getAttribute(String name)

getAttributeNames

public String[] getAttributeNames()

getAlgorithm

public String getAlgorithm()

getPassword

public String getPassword()

matches

public boolean matches(SimpleCredentials credentials)
                throws NoSuchAlgorithmException,
                       UnsupportedEncodingException

Compares this instance with the given SimpleCredentials and returns true if both match. Successful match is defined to be the result of

• Case-insensitive comparison of the UserIDs
• Equality of the passwords if the password contained in the simple credentials is hashed with the algorithm defined in this credentials object.

NOTE, that the simple credentials are exptected to contain the plain text password.

Parameters:

credentials - An instance of simple credentials.

Returns:

true if UserID and Password match.

Throws:

NoSuchAlgorithmException

UnsupportedEncodingException
