我正在使用AES加密一個字符串,並且想要在其他電腦上解密它。如果我在同一臺PC上執行加密和解密工作。但是對於其他電腦上的解密,我的加密算法正在生成一個「密碼密碼」,這是密鑰的另一端解密所需要的。我不知道如何將密碼轉移到另一端。AES加密和解密Java
這裏是我的代碼
public class AESCrypt {
static String plainText;
static byte[] plainBytesDecrypted = new byte[1024];
static byte[] cipherBytes = new byte[1024];
static SecretKey key;
static Cipher cipher;
public AESCrypt() throws NoSuchAlgorithmException {
KeyGenerator generator = KeyGenerator.getInstance("AES");
generator.init(128);
key = generator.generateKey();
}
public static byte[] encryption(String plainBytes) {
try {
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
cipher = Cipher.getInstance("AES/CBC/PKCS5Padding", "BC");
cipher.init(Cipher.ENCRYPT_MODE, key);
cipherBytes = cipher.doFinal(plainBytes.getBytes());
System.out.println("Encrypted data : " + new String(cipherBytes));
} catch (Exception ex) {
ex.printStackTrace();
}
return cipherBytes;
}
private static String bytesToHex(byte[] hash) {
return DatatypeConverter.printHexBinary(hash);
}
public static String Decryption() throws InvalidKeyException, IllegalBlockSizeException, InvalidAlgorithmParameterException, BadPaddingException {
cipher.init(Cipher.DECRYPT_MODE, key, cipher.getParameters());
plainBytesDecrypted = cipher.doFinal(cipherBytes);
System.out.println("Decrypted data : " + new String(plainBytesDecrypted));
return (new String(plainBytesDecrypted));
}
}
您是否聽說過[Public-key cryptography](https://en.wikipedia.org/wiki/Public-key_cryptography)? –
