Examples with JcaPGPContentSignerBuilder org.bouncycastle.openpgp.operator.jcajce.JcaPGPContentSignerBuilder used on opensource projects

Example 1 with JcaPGPContentSignerBuilder

use of org.bouncycastle.openpgp.operator.jcajce.JcaPGPContentSignerBuilder in project camel by apache.

the class PGPKeyAccessDataFormat method createSignatureGenerator.

protected List<PGPSignatureGenerator> createSignatureGenerator(Exchange exchange, OutputStream out) throws Exception {
    if (secretKeyAccessor == null) {
        return null;
    }
    List<String> sigKeyUserids = determineSignaturenUserIds(exchange);
    List<PGPSecretKeyAndPrivateKeyAndUserId> sigSecretKeysWithPrivateKeyAndUserId = secretKeyAccessor.getSignerKeys(exchange, sigKeyUserids);
    if (sigSecretKeysWithPrivateKeyAndUserId.isEmpty()) {
        return null;
    }
    exchange.getOut().setHeader(NUMBER_OF_SIGNING_KEYS, Integer.valueOf(sigSecretKeysWithPrivateKeyAndUserId.size()));
    List<PGPSignatureGenerator> sigGens = new ArrayList<PGPSignatureGenerator>();
    for (PGPSecretKeyAndPrivateKeyAndUserId sigSecretKeyWithPrivateKeyAndUserId : sigSecretKeysWithPrivateKeyAndUserId) {
        PGPPrivateKey sigPrivateKey = sigSecretKeyWithPrivateKeyAndUserId.getPrivateKey();
        PGPSignatureSubpacketGenerator spGen = new PGPSignatureSubpacketGenerator();
        spGen.setSignerUserID(false, sigSecretKeyWithPrivateKeyAndUserId.getUserId());
        int algorithm = sigSecretKeyWithPrivateKeyAndUserId.getSecretKey().getPublicKey().getAlgorithm();
        PGPSignatureGenerator sigGen = new PGPSignatureGenerator(new JcaPGPContentSignerBuilder(algorithm, findHashAlgorithm(exchange)).setProvider(getProvider()));
        sigGen.init(PGPSignature.BINARY_DOCUMENT, sigPrivateKey);
        sigGen.setHashedSubpackets(spGen.generate());
        sigGen.generateOnePassVersion(false).encode(out);
        sigGens.add(sigGen);
    }
    return sigGens;
}

Example 2 with JcaPGPContentSignerBuilder

use of org.bouncycastle.openpgp.operator.jcajce.JcaPGPContentSignerBuilder in project camel by apache.

the class PGPDataFormatTest method createSignature.

private void createSignature(OutputStream out) throws Exception {
    PGPSecretKey pgpSec = readSecretKey();
    PGPPrivateKey pgpPrivKey = pgpSec.extractPrivateKey(new JcePBESecretKeyDecryptorBuilder().setProvider(getProvider()).build("sdude".toCharArray()));
    PGPSignatureGenerator sGen = new PGPSignatureGenerator(new JcaPGPContentSignerBuilder(pgpSec.getPublicKey().getAlgorithm(), HashAlgorithmTags.SHA1).setProvider(getProvider()));

    BCPGOutputStream bOut = new BCPGOutputStream(out);
    InputStream fIn = new ByteArrayInputStream("Test Signature".getBytes("UTF-8"));
    int ch;
    while ((ch = fIn.read()) >= 0) {
        sGen.update((byte) ch);
    }
    fIn.close();
    sGen.generate().encode(bOut);
