/**
 * Sign the given content using the private and public keys from the keySet, and return the encoded CMS (PKCS#7) data.
 * Use of direct signature and DER encoding produces a block that is verifiable by Android recovery programs.
 */
public static byte[] generate(KeySet keySet, byte[] content) {
    try {
        List certList = new ArrayList();
        CMSTypedData msg = new CMSProcessableByteArray(content);

        certList.add(keySet.getPublicKey());

        Store certs = new JcaCertStore(certList);

        CMSSignedDataGenerator gen = new CMSSignedDataGenerator();

        JcaContentSignerBuilder jcaContentSignerBuilder = new JcaContentSignerBuilder(keySet.getSignatureAlgorithm()).setProvider("SC");
