aes/cbc/pkcs5padding加密代码

以下是Java实现AES/CBC/PKCS5Padding加密的代码实例：

import javax.crypto.Cipher;import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

public class AESEncrypter {
    private static final String IV_PARAMETER = "1234567890123456"; // 16 bytes IV
    private static final String ENCODING = "UTF-8";
    private static final String ALGORITHM = "AES/CBC/PKCS5Padding";
    private static final String SECRET_KEY = "0123456789123456"; // 16 bytes secret key

    public static String encrypt(String plainText) {
        try {
            IvParameterSpec iv = new IvParameterSpec(IV_PARAMETER.getBytes(ENCODING));
            SecretKeySpec skeySpec = new SecretKeySpec(SECRET_KEY.getBytes(ENCODING), "AES");

            Cipher cipher = Cipher.getInstance(ALGORITHM);
            cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);

            byte[] encrypted = cipher.doFinal(plainText.getBytes());
            return new String(Base64.encodeBase64(encrypted), ENCODING);
        } catch (Exception ex) {
            ex.printStackTrace();
        }

        return null;
    }
}

请注意，这只是一个简单的例子，仅供参考。如果要在生产环境中使用，需要更多的安全措施和更好的错误处理。
