Changes

• 09-25-2008-Added space removing function call in the upper level decrypt call to prevent crash on bad parsing-JSB
• 09-26-2008-Added HTML/BB Code output switching in Encryption Control Panel.-JSB
• 10-02-2008-Noticed that class was not declared public, which made export to other programs difficult. Fixed.-JSB
• 10-02-2008-Created a indentifier string field for consistency in encryption entry identifiers and parsers-JSB
• 10-04-2008-Added comma-delimited flat style output for use in non-applet deployments and Crow utility-JSB
• 10-06-2008-Added helper functions parseID, usesPWIVector, getClassID to make Blackbird package easily adapted for use by the Crow program-JSB
• 10-13-2008-Now using an all-space removing function in the static SpaceRemover class-JSB

Constructor Summary

ROT13(int x)

Method Summary

java.lang.String	decrypt(java.lang.String strArgList) This is the upper level decrypt call into this class.
byte[]	encrypt(byte[] b) This is ROT13s encryption function that, as expected is quite simple.
java.lang.String	getClassID() Return the class identification string.
int	getIndex() Return the assigned index of this class.
java.lang.String	getJavaScriptCode() This function is very important.
java.awt.MenuItem[]	getMenuItems() When the applet launches, each class that is created is queried for its own menu items that are needed to use the control panels.
int	getOPCode(java.lang.String s) Opecode is returned to tell the main applet which part of this class' control panels to launch.
void	killPanel() Internally, there is only one panel to kill, the one used for encryption.
java.lang.String	parseID(java.lang.String arglist) parseID is used by those entities that need to single out an Identifier string needed by a using class to find out "who" created the encryption entry.
void	setFrameTarget(int i) setFrameTarget is used to set a variable that is concated in the Javascript generation function that is set pertaining to the "position" the applet resides in the DOM.
void	setID(java.lang.String sid) Not used in ROT13
boolean	setPasswordExternally(java.lang.String p)
void	showEncryptionControlPanel(int i, java.awt.Image iconImage, java.lang.Object o) Generic function taking arguments that can direct it to display more than one kind of control panel.
boolean	testRuntime() This function always returns true, as there is no third party runtime.
boolean	usesPWIVector() Some Encryption entities use passwords or initialization vectors.

Method Detail

encrypt

public byte[] encrypt(byte[] b)

This is ROT13s encryption function that, as expected is quite simple.

Parameters:

b -

Returns:

getJavaScriptCode

public java.lang.String getJavaScriptCode()

This function is very important. The applet uses it to get the JavaScript code against which to try an eval function. This code calls back into the applet.

Specified by:

getJavaScriptCode in interface EncryptionEntity

Returns:

showEncryptionControlPanel

public void showEncryptionControlPanel(int i,
                                       java.awt.Image iconImage,
                                       java.lang.Object o)

Generic function taking arguments that can direct it to display more than one kind of control panel. ROT13 only has one panel.

Specified by:

showEncryptionControlPanel in interface EncryptionEntity

Parameters:

i -

iconImage -

o -

getMenuItems

public java.awt.MenuItem[] getMenuItems()

When the applet launches, each class that is created is queried for its own menu items that are needed to use the control panels.

Specified by:

getMenuItems in interface EncryptionEntity

Returns:

getIndex

public int getIndex()

Return the assigned index of this class.

Specified by:

getIndex in interface EncryptionEntity

Returns:

killPanel

public void killPanel()

Internally, there is only one panel to kill, the one used for encryption.

Specified by:

killPanel in interface EncryptionEntity

getOPCode

public int getOPCode(java.lang.String s)

Opecode is returned to tell the main applet which part of this class' control panels to launch.

Specified by:

getOPCode in interface EncryptionEntity

Parameters:

s -

Returns:

testRuntime

public boolean testRuntime()

This function always returns true, as there is no third party runtime.

Specified by:

testRuntime in interface EncryptionEntity

Returns:

setPasswordExternally

public boolean setPasswordExternally(java.lang.String p)

Specified by:

setPasswordExternally in interface EncryptionEntity

decrypt

public java.lang.String decrypt(java.lang.String strArgList)

This is the upper level decrypt call into this class. Because ROT13 takes only the byte array string as a single argument, there is only the processing of the array.

Specified by:

decrypt in interface EncryptionEntity

Parameters:

strArgList -

Returns:

setFrameTarget

public void setFrameTarget(int i)

setFrameTarget is used to set a variable that is concated in the Javascript generation function that is set pertaining to the "position" the applet resides in the DOM. What is meant by "Frame Target" is the name of the frame, derived from the frames Name parameter that the applet must invoke Javascript callback results into.

Specified by:

setFrameTarget in interface EncryptionEntity

Parameters:

i -

getClassID

public java.lang.String getClassID()

Return the class identification string.

Specified by:

getClassID in interface EncryptionEntity

Returns:

usesPWIVector

public boolean usesPWIVector()

Some Encryption entities use passwords or initialization vectors. Using programs may need to know that in some cases.

Specified by:

usesPWIVector in interface EncryptionEntity

Returns:

parseID

public java.lang.String parseID(java.lang.String arglist)

parseID is used by those entities that need to single out an Identifier string needed by a using class to find out "who" created the encryption entry. This is not needed by those classes that need not single out an encryption entry for a particuler initialization vector or password. Different classes that use this might have this Identifier is different parts of comma-delimited listing.

Specified by:

parseID in interface EncryptionEntity

Parameters:

arglist -

Returns:

setID

public void setID(java.lang.String sid)

Not used in ROT13

Specified by:

setID in interface EncryptionEntity

Parameters:

sid -
