rsa js pidCrypt加密java解密

Question

我正在尝试使用pidCrypt在浏览器中加密一些简单的消息，然后在服务器上使用java crypto对其进行解密。但我不断收到错误消息：

javax.crypto.IllegalBlockSizeException：数据不得超过128个字节

键：

使用openssl genrsa（sslery）生成

键。 然后私钥转换为pkcs＃8 der格式并读入java代码

JS代码段：

/*---* ENCRYPT: RSA 1024 bit ---------*/  

 // public key  
 var params = certParser(publickey);  
 var key = pidCryptUtil.decodeBase64(params.b64);  


 // new RSA instance  
 var rsa = new pidCrypt.RSA();  


/* RSA encryption 
 * get the modulus and exponent from certificate (ASN1 parsing) 
 * pem(Array of Bytes)        
 */  

 // ASN1 parsing  
 var asn = pidCrypt.ASN1.decode(pidCryptUtil.toByteArray(key));  
 var tree = asn.toHexTree();  

 // setting the public key for encryption with retrieved ASN.1 tree  
 rsa.setPublicKeyFromASN(tree);  

 /*** encrypt */  
 var crypted = rsa.encrypt(plaintext);  
 //var crypted64 = pidCryptUtil.encodeBase64(crypted);

java code snippet：

       Cipher cipher = Cipher.getInstance("RSA");  
       cipher.init(Cipher.DECRYPT_MODE, myPrivKey);  
       byte[] descryptedData = cipher.doFinal(cyphertext.getBytes());
