Summary

RSA asymmetric encryption should be used only with OAEP padding (Optimal Asymmetric Encryption Padding).

Description

This means that any encryption or decryption processes involving RSA should adhere to the OAEP padding scheme. OAEP is considered more secure than older padding schemes. Padding schemes are employed to add randomness and complexity to the plaintext before being encrypted to enhance security.
