public void verify(PublicKey key, String sigProvider) throws CRLException, NoSuchAlgorithmException, InvalidKeyException, NoSuchProviderException, SignatureException {
    if (!c.getSignatureAlgorithm().equals(c.getTBSCertList().getSignature())) {
        throw new CRLException("Signature algorithm on CertificateList does not match TBSCertList.");
    }
    Signature sig = Signature.getInstance(getSigAlgName(), sigProvider);
    sig.initVerify(key);
    sig.update(this.getTBSCertList());
    if (!sig.verify(this.getSignature())) {
        throw new SignatureException("CRL does not verify with supplied public key.");
    }
}

Example 27 with Signature

use of java.security.Signature in project XobotOS by xamarin.

the class X509CertificateObject method verify.

public final void verify(PublicKey key) throws CertificateException, NoSuchAlgorithmException, InvalidKeyException, NoSuchProviderException, SignatureException {
    Signature signature;
    String sigName = X509SignatureUtil.getSignatureName(c.getSignatureAlgorithm());
    try {
        signature = Signature.getInstance(sigName, BouncyCastleProvider.PROVIDER_NAME);
    } catch (Exception e) {
        signature = Signature.getInstance(sigName);
    }
    checkSignature(key, signature);
}

Example 28 with Signature

use of java.security.Signature in project XobotOS by xamarin.

the class X509CertificateObject method verify.

public final void verify(PublicKey key, String sigProvider) throws CertificateException, NoSuchAlgorithmException, InvalidKeyException, NoSuchProviderException, SignatureException {
    String sigName = X509SignatureUtil.getSignatureName(c.getSignatureAlgorithm());
    Signature signature = Signature.getInstance(sigName, sigProvider);
    checkSignature(key, signature);
}

Example 29 with Signature

use of java.security.Signature in project camel by apache.

the class RSAKeyPairIdentity method getSignature.

@Override
public byte[] getSignature(byte[] data) {
    PrivateKey prvKey = keyPair.getPrivate();
    Signature sig;
    try {
        sig = Signature.getInstance("SHA1withRSA");
        sig.initSign(prvKey);
        sig.update(data);
        byte[] sshRsa = ALGORITHM_TYPE.getBytes();
        byte[] signature = sig.sign();
        byte[] result = new byte[sshRsa.length + 4 + signature.length + 4];
        int index = 0;
        byte[] intAsByteArray = ByteBuffer.allocate(4).putInt(sshRsa.length).array();
        System.arraycopy(intAsByteArray, 0, result, index, 4);
        index += 4;
        System.arraycopy(sshRsa, 0, result, index, sshRsa.length);
        index += sshRsa.length;
        intAsByteArray = ByteBuffer.allocate(4).putInt(signature.length).array();
        System.arraycopy(intAsByteArray, 0, result, index, 4);
        index += 4;
        System.arraycopy(signature, 0, result, index, signature.length);
        return result;
    } catch (NoSuchAlgorithmException e) {
        log.error("Cannot sign", e);
    } catch (InvalidKeyException e) {
        log.error("Cannot sign", e);
    } catch (SignatureException e) {
        log.error("Cannot sign", e);
    }
    return null;
}

Example 30 with Signature

use of java.security.Signature in project camel by apache.

the class SigningProcessor method process.

public void process(Exchange exchange) throws Exception {
    Signature service = initSignatureService(exchange);
    calculateSignature(exchange, service);
    byte[] signature = service.sign();
    Message in = exchange.getIn();
    clearMessageHeaders(in);
    Message out = exchange.getOut();
    out.copyFrom(in);
    out.setHeader(config.getSignatureHeaderName(), new Base64().encode(signature));
