我已生成一个带有java代码的私钥,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();
现在我想要将密码添加到私钥。 所以我找到了这段代码:
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 -in privateKey.key 我没有错误,但当我尝试这个: openssl rsa -noout -modulus -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_CHECK_TLEN:错误标记:。\ crypto \ as n1 \ tasn_dec.c:1319: 9964:错误:0D06C03A:asn1编码 例程:ASN1_D2I_EX_PRIMITIVE:嵌套asn1错误 或:。\ crypto \ asn1 \ tasn_dec.c:831:9964:错误:0D08303A:asn1编码 例程:ASN1_TEMPLATE_NOEXP_D2I:嵌套asn1 e RROR:\加密\ ASN1 \ tasn_dec.c:751:场=版本, 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: Proc-Type:4,ENCRYPTED “DEK-Info:”+“AES-256-CBC”...... 但我如何添加这个(我得到这些信息?)? TNX
答案 0 :(得分:1)
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: 较新的应用程序应该使用更安全的PKCS#8格式 pkcs8实用程序。
