使用openssl进行phpseclib RSA解密

I used phpseclib for encryption, have some problem with openssl decrypt

//generate keys
extract($rsa->createKey(1024));
file_put_contents("public.pem",$publickey);
file_put_contents("private.pem",$privatekey);

encrypt text

    $rsa->loadKey($public_key); // public key
    $plaintext = '...';
    $ciphertext = $rsa->encrypt($plaintext);
    file_put_contents("ciphertext.txt",$ciphertext);

So in linux i'm decrypting :

xxd -p ciphertext.txt | tr -d '
' 

And finally like the following command

openssl rsautl -decrypt -inkey private.pem

get this error :

error:0407106B:rsa routines:RSA_padding_check_PKCS1_type_2:block type is not 02:rsa_pk1.c:190:
error:04065072:rsa routines:RSA_EAY_PRIVATE_DECRYPT:padding check failed:rsa_eay.c:674:

I am doing these settings for phpseclib :

define('CRYPT_RSA_PKCS15_COMPAT', true);

and now get this error on openssl:

error:04065084:rsa routines:RSA_EAY_PRIVATE_DECRYPT:data too large for modulus:rsa_eay.c:590:

public key :
