java相互加密解密

java代码

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.util.Base64;

public class AesUtils {

    public static String encrypt(String plaintext, String key, String iv) throws Exception {
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        SecretKeySpec keySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");
        IvParameterSpec ivSpec = new IvParameterSpec(iv.getBytes("UTF-8"));
        cipher.init(Cipher.ENCRYPT_MODE, keySpec, ivSpec);
        byte[] encryptedBytes = cipher.doFinal(plaintext.getBytes("UTF-8"));
        return Base64.getEncoder().encodeToString(encryptedBytes);
    }


    public static String decrypt(String encryptedText, String key, String iv) throws Exception {
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        SecretKeySpec keySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");
        IvParameterSpec ivSpec = new IvParameterSpec(iv.getBytes("UTF-8"));
        cipher.init(Cipher.DECRYPT_MODE, keySpec, ivSpec);
        byte[] decryptedBytes = cipher.doFinal(Base64.getDecoder().decode(encryptedText));
        return new String(decryptedBytes, "UTF-8");
    }
