Constructor Details

AbstractAlgorithm

public AbstractAlgorithm(String uri,
 int order,
 String jcaName)

Constructor.

Parameters:

uri - the algorithm URI

order - the ordering for the algorithm

jcaName - the JCA name

AbstractAlgorithm

protected AbstractAlgorithm(String uri)

Protected constructor used by builders.

Parameters:

uri - the algorithm URI

Method Details

getUri

public String getUri()

Gets the URI representation of the algorithm.

Specified by:

getUri in interface Algorithm

Returns:

the URI

getJcaName

public String getJcaName()

Gets the JCA (Java Cryptography Architecture) name.

Specified by:

getJcaName in interface Algorithm

Returns:

the JCA name

getOrder

public int getOrder()

Gets the order for an algorithm where a lower order is seen as more preferable than an algorithm with a higher ordering. The ordering is relative to algorithms of the same type, and also other critera such as key or key length material.

Specified by:

getOrder in interface Algorithm

Returns:

a positive integer

setJcaName

protected void setJcaName(String jcaName)

Assigns the JCA name.

Parameters:

jcaName - the JCA name

setOrder

protected void setOrder(int order)

Assigns the algorithm order.

Parameters:

order - the order

isBlacklisted

public boolean isBlacklisted()

Tells whether this algorithm is black-listed, i.e., configured to not be allowed.

Specified by:

isBlacklisted in interface Algorithm

Returns:

true if the algorithm is black-listed and false otherwise

setBlacklisted

public void setBlacklisted(boolean blacklisted)

Sets whether this algorithm is blacklisted. The default is false.

Parameters:

blacklisted - whether this algorithm is blacklisted

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
