            } else {
                throw new InvalidKeyException("can't recognise key type in DSA based signer");
            }
        } catch (Exception e) {
            throw new InvalidKeyException("can't recognise key type in DSA based signer");
        }
    }
    digest.reset();
    signer.init(false, param);
}

Example 7 with DSAKey

use of java.security.interfaces.DSAKey in project jdk8u_jdk by JetBrains.

the class DOMSignatureMethod method sign.

byte[] sign(Key key, SignedInfo si, XMLSignContext context) throws InvalidKeyException, XMLSignatureException {
    if (key == null || si == null) {
        throw new NullPointerException();
    }
    if (!(key instanceof PrivateKey)) {

        } catch (NoSuchAlgorithmException nsae) {

        }
    }
    signature.initSign((PrivateKey) key);
    if (log.isLoggable(java.util.logging.Level.FINE)) {
        log.log(java.util.logging.Level.FINE, "Signature provider:" + signature.getProvider());
        log.log(java.util.logging.Level.FINE, "Signing with key: " + key);
    }
    ((DOMSignedInfo) si).canonicalize(context, new SignerOutputStream(signature));
    try {
        Type type = getAlgorithmType();
        if (type == Type.DSA) {
            int size = ((DSAKey) key).getParams().getQ().bitLength();
            return JavaUtils.convertDsaASN1toXMLDSIG(signature.sign(), size / 8);
        } else if (type == Type.ECDSA) {
            return SignatureECDSA.convertASN1toXMLDSIG(signature.sign());
        } else {
            return signature.sign();
        }
    } catch (SignatureException se) {
        throw new XMLSignatureException(se);
    } catch (IOException ioe) {
        throw new XMLSignatureException(ioe);
    }

Example 8 with DSAKey

use of java.security.interfaces.DSAKey in project nhin-d by DirectProject.
