public class Signature
extends Object
implements org.apache.pdfbox.pdmodel.interactive.digitalsignature.SignatureInterface

SignatureInterface sample implementation.

Use your favorite cryptographic library to implement PKCS #7 signature creation. If you want to create the hash and the signature separately (e.g. to transfer only the hash to an external application), read this answer or this answer.
