用java代码加密私钥

用java代码加密私钥,java,encryption,private-key,ejbca,Java,Encryption,Private Key,Ejbca,我用java代码生成了一个私钥,并将其保存为: KeyPair keys; try { keys = KeyTools.genKeys("2048", AlgorithmConstants.KEYALGORITHM_RSA); //SAVE PRIVKEY //PrivateKey privKey = keys.getPrivate(); //byte[] privateKeyBytes = privKey.getEncod

我用java代码生成了一个私钥,并将其保存为:

KeyPair keys;
    try {
        keys = KeyTools.genKeys("2048", AlgorithmConstants.KEYALGORITHM_RSA);
        //SAVE PRIVKEY
        //PrivateKey privKey = keys.getPrivate();
        //byte[] privateKeyBytes = privKey.getEncoded();
        PKCS10CertificationRequest  pkcs10 = new PKCS10CertificationRequest("SHA256WithRSA",
                CertTools.stringToBcX509Name("CN=NOUSED"), keys.getPublic(), null, keys.getPrivate());

        //Save Privatekey
        String privateKeyFilename = "C:/Users/l.calicchio/Downloads/privateKey.key";
        String password="prismaPrivateKey";
        byte[] start="-----BEGIN PRIVATE KEY-----\n".getBytes();
        byte[] end="\n-----END PRIVATE KEY-----".getBytes();
        byte[] privateKeyBytes = keys.getPrivate().getEncoded();

        byte[] encryptedPrivateKeyBytes = passwordEncrypt(password.toCharArray(), privateKeyBytes);

        File f=new File(privateKeyFilename);
        if (f.exists()){
            f.delete();
        }

        FileOutputStream fos = new FileOutputStream(f,true);
        fos.write(start);
        fos.write(Base64.encode(encryptedPrivateKeyBytes));
        fos.write(end);
        fos.close();
现在我想将密码短语添加到私钥中。 所以我找到了这个代码:

private static byte[] passwordEncrypt(char[] password, byte[] plaintext) throws Exception {
    String MYPBEALG = "PBEWithSHA1AndDESede";

    int count = 20;// hash iteration count
    SecureRandom random = new SecureRandom();
    byte[] salt = new byte[8];
    random.nextBytes(salt);

    // Create PBE parameter set
    PBEParameterSpec pbeParamSpec = new PBEParameterSpec(salt, count);
    PBEKeySpec pbeKeySpec = new PBEKeySpec(password);
    SecretKeyFactory keyFac = SecretKeyFactory.getInstance(MYPBEALG);
    SecretKey pbeKey = keyFac.generateSecret(pbeKeySpec);

    Cipher pbeCipher = Cipher.getInstance(MYPBEALG);

    // Initialize PBE Cipher with key and parameters
    pbeCipher.init(Cipher.ENCRYPT_MODE, pbeKey, pbeParamSpec);

    // Encrypt the encoded Private Key with the PBE key
    byte[] ciphertext = pbeCipher.doFinal(plaintext);

    // Now construct  PKCS #8 EncryptedPrivateKeyInfo object
    AlgorithmParameters algparms = AlgorithmParameters.getInstance(MYPBEALG);
    algparms.init(pbeParamSpec);
    EncryptedPrivateKeyInfo encinfo = new EncryptedPrivateKeyInfo(algparms, ciphertext);

    // and here we have it! a DER encoded PKCS#8 encrypted key!
    return encinfo.getEncoded();
但是当我使用这个openssl命令时 openssl asn1parse-在privateKey.key中 我没有错误,但当我尝试以下操作时: openssl rsa-noout-module-in privatekey.it 我有一个错误:

无法加载私钥9964:错误:0D0680A8:asn1编码 例程:ASN1\u检查\u TLEN:错误的标记:.\crypto\as n1\tasn\u dec.c:1319: 9964:错误:0D06C03A:asn1编码 例程:ASN1\U D2I\U EX\U原语:嵌套ASN1 err 或:。\crypto\asn1\tasn_dec.c:831:9964:错误:0D08303A:asn1编码 例程:ASN1\U模板\U NOEXP\U D2I:嵌套ASN1 e 错误:.\crypto\asn1\tasn\u dec.c:751:Field=version, Type=PKCS8_PRIV_KEY_INFO 9964:错误:0907B00D:PEM 例程:PEM_READ_BIO_PRIVATEKEY:ASN1 lib:。\crypto\PEM\p em_pkey.c:132:

我认为私钥缺少以下行: 进程类型:4,加密 “DEK信息:”+“AES-256-CBC”。。。。。。 但是我如何添加这些信息(从哪里获得这些信息?)?
tnx

请阅读手册,
man rsa
提供以下详细信息:

注意:此命令使用 用于私钥加密的传统SSLeay兼容格式: 较新的应用程序应使用更安全的PKCS#8格式,使用 pkcs8实用程序


我的回答有什么遗漏吗,卢卡?
