Yes, I know the constant is defined, but the functionality isn't there.
I can run the EncryptWithCertificate.java example from the book fine.
However, if I change ENCRYPTION_AES_128 to ENCRYPTION_AES_256 in this
example (in the two locations that it occurs), then I get:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException
at java.lang.System.arraycopy(Native Method)

com.itextpdf.text.pdf.PdfEncryption.getEncryptionDictionary(PdfEncryption.java:633)

at
part3.chapter12.EncryptWithCertificate.createPdf(EncryptWithCertificate.java:73)
at
part3.chapter12.EncryptWithCertificate.main(EncryptWithCertificate.java:178)
This behaviour was mentioned in a previous message on this list - the
explanation at the time was that the AES-256 functionality wasn't
implemented yet.
I have installed the Unlimited Strength Jurisdiction Policy Files, and the
example code installs the BouncyCastle crypto provider:
Security.addProvider(new BouncyCastleProvider());
