9. Check the file Vendor/Riverslei/payment/src/helpers/strutil.php, and you will find that the RSA private key in PKCS#1 format will be automatically changed (to MieVQ… Beginning, without leading and tailing), convert to the RSA private key in the old version of PKCS#1. In the end, it is still found that the error is still reported: SUB_MSG [checking error, it is recommended to check whether the signature string or signed private key matches the application public key, and the verification string generated by the gateway is
