byte[] bytes = cipher.doFinal(str.getBytes("utf-8")); String result = new BASE64Encoder().encode(bytes); result = result.toString().replaceAll("\r\n", ""); result = result.replaceAll("\\+", ADD); return result;

这段代码的作用是将字符串进行加密，并返回加密后的结果。首先，使用指定的加密算法对字符串进行加密操作。然后，将加密后的结果转换为字节数组。接下来，将字节数组使用Base64编码转换为字符串。最后，对字符串进行一些替换操作，去除换行符并将加号替换为ADD。最终，返回加密后的结果字符串。

请注意，代码中的ADD是一个变量，需要提前定义。另外，这段代码使用了Java标准库中的一些类和方法，需要先导入相应的包。

将以下JAVA代码转为PHP代码：import javax.crypto.Cipher; import javax.crypto.spec.SecretKeySpec; import java.util.Base64; public class AesTool { public static String encrypt(String str, String key) throws Exception { Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding"); SecretKeySpec keySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES"); cipher.init(Cipher.ENCRYPT_MODE, keySpec); byte[] result = cipher.doFinal(str.getBytes("UTF-8")); return Base64.getEncoder().encodeToString(result); } public static String decrypt(String base64Str, String key) throws Exception { Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding"); SecretKeySpec keySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES"); cipher.init(Cipher.DECRYPT_MODE, keySpec); byte[] decoded = cipher.doFinal(Base64.getDecoder().decode(base64Str)); return new String(decoded, "UTF-8"); } }

以下是将JAVA代码转换为PHP代码的示例：

<?php
class AesTool {
    public static function encrypt($str, $key) {
        $cipher = "AES-128-ECB";
        $ivlen = openssl_cipher_iv_length($cipher);
        $iv = openssl_random_pseudo_bytes($ivlen);
        $result = openssl_encrypt($str, $cipher, $key, OPENSSL_RAW_DATA, $iv);
        return base64_encode($result);
    }

    public static function decrypt($base64Str, $key) {
        $cipher = "AES-128-ECB";
        $base64Str = base64_decode($base64Str);
        $ivlen = openssl_cipher_iv_length($cipher);
        $iv = openssl_random_pseudo_bytes($ivlen);
        $decoded = openssl_decrypt($base64Str, $cipher, $key, OPENSSL_RAW_DATA, $iv);
        return $decoded;
    }
}

在这个PHP代码示例中，我们使用了openssl扩展来实现AES算法的加解密，使用的是128位密钥和ECB模式，并且使用PKCS5Padding对明文进行了补位。

public static String encryptRSA(String encodeValue) { String decryptValue = ""; try { String privateKey = CryptoRsaKey_NEO.getPrivateKey(); RSAPrivateKey privateKey1 = (RSAPrivateKey)getPrivateKeyDec(privateKey); byte[] decBytesBase64 = encodeValue.getBytes(); Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding"); cipher.init(Cipher.DECRYPT_MODE, privateKey1); byte[] resultBytes = cipher.doFinal(decBytesBase64); String aaa = new String(resultBytes,"UTF-8"); String bbb = Arrays.toString(resultBytes); System.out.println("Base64‘OaaaF" + aaa); System.out.println("Base64‘ObbbF" + bbb); decryptValue = new String(java.util.Base64.getEncoder().encode(resultBytes)); } catch (Exception e) { WPLErrUtil.logger("CipherUtil", "decryptRSA", "RSA" + encodeValue + "," + e.getMessage() + ":" + e.toString()); return null; } return decryptValue; }请根据上面的解密方法写出对应的加密方法

根据上面的解密方法，可以编写对应的加密方法如下：

public static String encryptRSA(String plainValue) { 
    String encryptValue = "";
    try {
        String publicKey = CryptoRsaKey_NEO.getPublicKey();
        RSAPublicKey publicKey1 = (RSAPublicKey)getPublicKeyDec(publicKey);
        byte[] plainBytes = plainValue.getBytes("UTF-8");
        Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
        cipher.init(Cipher.ENCRYPT_MODE, publicKey1);
        byte[] resultBytes = cipher.doFinal(plainBytes);
        encryptValue = java.util.Base64.getEncoder().encodeToString(resultBytes);
    } catch (Exception e) {
        WPLErrUtil.logger("CipherUtil", "encryptRSA", "RSA" + plainValue + "," + e.getMessage() + ":" + e.toString());
        return null;
    }
    return encryptValue;
}

这个方法接收一个字符串参数作为明文，返回一个字符串作为密文。它使用了与解密方法中相同的公钥和填充方式，然后将明文转换为字节数组，使用公钥进行加密，并将结果字节数组转换为Base64编码的字符串。
