我正在使用以下代码:
@Test
public void simpleEncryptDecryptTest_shouldSucceed() throws IOException, NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, IllegalBlockSizeException, BadPaddingException {
String text = "ASDF-asdföjk_\n394ysf";
String encryptedText = null;
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
PEMReader in = new PEMReader(new FileReader("C:/Users/User/tu/vs_exc3/keys/auction-server.pem"), new PasswordFinder() {
@Override
public char[] getPassword() {
return new char[] {'2', '3', '4', '5', '6'};
}
});
PrivateKey privateKey = (PrivateKey)in.readObject();
in = new PEMReader(new FileReader("C:/Users/User/tu/vs_exc3/keys/auction-server.pub.pem"));
PublicKey publicKey = (PublicKey)in.readObject();
Cipher decodeCipher = Cipher.getInstance("RSA/NONE/OAEPWithSHA256AndMGF1Padding");
Cipher encodeCipher = Cipher.getInstance("RSA/NONE/OAEPWithSHA256AndMGF1Padding");
decodeCipher.init(Cipher.DECRYPT_MODE, privateKey);
encodeCipher.init(Cipher.ENCRYPT_MODE, publicKey);
byte[] encrypted = encodeCipher.doFinal(text.getBytes());
encryptedText = new String(encrypted);
byte[] decrypted = decodeCipher.doFinal(encryptedText.getBytes());
Assert.assertTrue(text.equals(new String(decrypted)));
}
我得到以下例外:
org.bouncycastle.openssl.EncryptionException: exception using cipher - please check password and data.

我已经在JRE和我的JDK目录中安装了JCE无限强度文件。什么可能导致例外?
编辑1: 私钥文件如下所示:
-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: AES-256-CBC,8429830AD224E4D56A21C3C680D6EA57
key...
-----END RSA PRIVATE KEY-----
答案 0 :(得分:0)
这是一个较晚的答案,但我遇到了同样的问题。我正在Tomcat上部署Web应用程序,并且在解密密钥时遇到相同的错误。 Unlimited Strength Jurisdiction Policy
文件已正确安装。这是可行的,然后我们在服务器上更新了Tomcat,开始出现Caused by: java.security.InvalidKeyException: Illegal key size
异常。
事实证明,问题出在Tomcat服务。它在jdk中调用Java jre与Java jre,而jre没有增强的jar文件。
此堆栈答案可能对更改正在使用的Java tomcat的版本很有用: How to change Java version used by TOMCAT?
尽管我的问题与Tomcat有关,但我相信这也可能是在任何环境中运行Java的问题。
