Class PKCS7SignedData

All Implemented Interfaces:

PKCSObjectIdentifiers

Deprecated. this class really is obsolete - use the CMS package.

public class PKCS7SignedData
extends java.lang.Object
implements PKCSObjectIdentifiers

Represents a PKCS#7 object - specifically the "Signed Data" type.

How to use it? To verify a signature, do:

 PKCS7SignedData pkcs7 = new PKCS7SignedData(der_bytes);        // Create it
 pkcs7.update(bytes, 0, bytes.length);                          // Update checksum
 boolean verified = pkcs7.verify();                             // Does it add up?

 To sign, do this:
 PKCS7SignedData pkcs7 = new PKCS7SignedData(privKey, certChain, "MD5");
 pkcs7.update(bytes, 0, bytes.length);                          // Update checksum
 pkcs7.sign();                                                  // Create digest

 bytes = pkcs7.getEncoded();                                    // Write it somewhere
 

This class is pretty close to obsolete, for a much better (and more complete) implementation of PKCS7 have a look at the org.bouncycastle.cms package.
