Library API
The library has a very simple API which is shown here. For more detailed information aee the library reference.
| Creating the stegan |
|---|
|
Steganos.embedImage(String pphrase, PImage carrier, PImage
burden); Steganos.embedText(String pphrase, PImage carrier, String burden) |
| The first parameter is the pass phrase (password) used to encrpyt the burden, followed by the carrier iamge and finally the burden, be it image or text. |
| Extracting the burden from a stegan |
|---|
|
Steganos.extractImage(String pphrase, PImage stegan); Steganos.extractText(String pphrase, PImage carrier, String burden) |
| The first parameter is the pass phrase (password) used to decrpyt the burden once it has been extracted from the stegan. These methods return a PImage or String object respectively. |
| Analysing a potential carrier / burden pair |
|---|
|
Steganos.analyze(PImage carrier, PImage burden); Steganos.analyze(PImage carrier, String burden) |
|
Both these return an Analysis object. The Analysis class has two public attributes |
| Encrypting / decrpting an image |
|---|
|
Encryption.encodeImage(String passphrase, PImage img, int
format) Encryption.decodeImage(String passphrase, PImage img, int format) |
| These two methods are used to encrypt and decrypt an image. These methods are used by the library and have been made available to the user. The last parameter should be ARGB or RGB |
