我需要使用 OpenSSL 和 Java 加密一个字符串,并让它们最终完全相同。
OpenSSL
openssl enc -aes-256-cbc -S THISISASECRETKEY -k ALSOISASECRETKEY -in $txtName -out $aesName -a
爪哇
import java.security.*;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import sun.misc.*;
public class Protector {
private static final String ALGORITHM = "AES";
private static final int ITERATIONS = 1;
private static final byte[] keyValue = "ALSOISASECRETKEY".getBytes();
public static String encrypt(String value, String salt) throws Exception {
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGORITHM);
c.init(Cipher.ENCRYPT_MODE, key);
String valueToEnc = null;
String eValue = value;
for (int i = 0; i < ITERATIONS; i++) {
valueToEnc = salt + eValue;
byte[] encValue = c.doFinal(valueToEnc.getBytes());
eValue = new BASE64Encoder().encode(encValue);
}
return eValue;
}
public static String decrypt(String value, String salt) throws Exception {
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGORITHM);
c.init(Cipher.DECRYPT_MODE, key);
String dValue = null;
String valueToDecrypt = value;
for (int i = 0; i < ITERATIONS; i++) {
byte[] decordedValue = new BASE64Decoder().decodeBuffer(valueToDecrypt);
byte[] decValue = c.doFinal(decordedValue);
dValue = new String(decValue).substring(salt.length());
valueToDecrypt = dValue;
}
return dValue;
}
private static Key generateKey() throws Exception {
Key key = new SecretKeySpec(keyValue, ALGORITHM);
// SecretKeyFactory keyFactory = SecretKeyFactory.getInstance(ALGORITHM);
// key = keyFactory.generateSecret(new DESKeySpec(keyValue));
return key;
}
}
和 Java 主要
public class main {
public static void main(String[] args) throws Exception {
String password = "This is a test!";
String salt = "THISISASECRETKEY";
String passwordEnc = Protector.encrypt(password, salt);
String passwordDec = Protector.decrypt(passwordEnc, salt);
System.out.println("Salt Text : " + salt);
System.out.println("Plain Text : " + password);
System.out.println("Encrypted : " + passwordEnc);
System.out.println("Decrypted : " + passwordDec);
}
}
Java 代码产生一个结果,但它不匹配。我需要将我的 Java 代码与确实必须保持不变的 OpenSSL 相匹配(与已经设置了很多后端的其他人一起工作)。我在某处读到 OpenSSL 和 Java 生成密钥的方式有所不同,如果这有帮助的话。
非常感谢您!
