Class JarSignature

java.lang.Object

com.sun.javafx.tools.packager.JarSignature

public class JarSignature
extends Object

(Source copied from: com.sun.deploy.security.JarSignature in Deploy workspace) This class is an abstraction of signature that is currently used for implementation of jar signing as BLOBs. There are 2 modes of use for this class - signing and validation and same instance of JarSignature object can not be reused. Signing mode: - create new instance using JarSignature.create() - add entries you want to include into the signature using updateWithEntry(). (Note the order is important.) - use getEncoded() to get bytes for the result signature Validation mode: - create new instance using JarSignature.load() - add entries using updateWithEntry() - use isValid() to validate result - use getCodeSigners() to get list of code signers used

Method Detail

load

public static JarSignature load(byte[] rawSignature)
                         throws sun.security.pkcs.ParsingException,
                                CertificateException,
                                IOException,
                                NoSuchAlgorithmException,
                                InvalidKeyException,
                                SignatureException

Loads jar signature from given byte array. If signature could not be reconstructed then exceptions are thrown.

Throws:

sun.security.pkcs.ParsingException

CertificateException

IOException

NoSuchAlgorithmException

InvalidKeyException

SignatureException

create

public static JarSignature create(PrivateKey privateKey,
                                  X509Certificate[] chain)
                           throws NoSuchAlgorithmException,
                                  InvalidKeyException

Creates new signature for signing.

Parameters:

privateKey - Key to be used for signing.

Returns:

Throws:

NoSuchAlgorithmException

InvalidKeyException

isValidationMode

public boolean isValidationMode()

getEncoded

public byte[] getEncoded()
                  throws NoSuchAlgorithmException,
                         SignatureException,
                         IOException

Returns encoded representation of signature.

Throws:

UnsupportedOperationException - if called in validation mode.

NoSuchAlgorithmException

SignatureException

IOException

updateWithZipEntry

public InputStream updateWithZipEntry(String name,
                                      InputStream is)
                               throws SignatureException

Performs partial validation of zip/jar entry with given name and data stream. Return wrapped version of input stream to complete validation. Stream need to be read fully for validation to be complete.

Throws:

SignatureException

update

public void update(byte[] v)
            throws SignatureException

Throws:

SignatureException

isValid

public boolean isValid()

getCodeSigners

public CodeSigner[] getCodeSigners()

signJarAsBLOB

                          ZipOutputStream jos)
                   throws IOException,
                          SignatureException,
                          NoSuchAlgorithmException

Throws:

IOException

SignatureException
