前端RSA加密密钥格式

Question

前端生成公钥方式：

let szPublicKeyString = Secure.generateRSAPublicKey(szMattsRSAkey);

前端有对公钥进行base64进行编码， 代码未体现
后端使用前端生成的公钥进行数据加密报错
后端使用的Hutool依赖包，代码如下：

public class RsaUtils {
    public static String encrypt(String content, String publicKey) {
        try{
            RSA rsa = new RSA(null,publicKey);
 return rsa.encryptBase64(content, KeyType.PublicKey);
 }catch (Exception e){
            e.printStackTrace();
 }
        return null;
 }
    
    public static void main(String[] args) {
        encrypt("xxxxx", "YTZhNTU2ODdkMjE3NzFlZGMxMjYw" +
                "MTczZGRmODE5NWI2ODY2ZGE5ZjI1YTVjZjAzMGJm" +
                "ZTdmYWNiZDIwMDExOTNjZTMwNmUyMTg1M2I3NGZmOWViZG" +
                "FiYmNkZmVjYmY3MTk3MDY4NDIxZWQ3YzNkMTZiN2M5ZDljYjFmNjlhYmM5M" +
                "zAwNWFiNjFiMWJlZDc0NThhYjAwZTdiMmRiYWU2ZjU0MzFhNjZiNjNjN2U4MDhmMjBkZG" +
                "JmODJmN2I1NTdjZDFiMDdlM2JjZmIxODFjOTRkMWYxMDM5MWM0YjA1ZDExYjJiMmY4MTVlO" +
                "DUwMjM2ODdkZTUwMGY1ZWEwNGE5Nw==");
 }
}

报错如下：

现在感觉是前后端生成公钥的方式不一致，导致后端这边无法使用前端的公钥进行加密
有没有大佬曾经搞过加密解密的，忘指点一下，卡这好久了，在卡要被劝退了

我们之前是后端生成的公钥, 前端用来加密字段
