Encryption and Decryption Mode

The values of the request parameter data and the response field data are both encrypted with RSA and then encrypted with base64urlsafe.
In traditional base64 encoding, there are two symbols, + and /, which will be directly escaped by the URL. Therefore, if you want to transmit these encoded strings via URL, you need to do traditional base64 encoding first, and then replace + and / with - _ respectively. On the receiving end, do the opposite decoding action.RSA encryption and decryption use segmented encryption.
