public class PKCS7SignedData extends Object implements PKCSObjectIdentifiers
Deprecated: this class really is obsolete - use the CMS package.
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.
