👉 In cryptography, the term "concealing" is used to refer to a technique in which an attacker cannot easily learn about the secret key or encryption algorithm. This can be achieved by using mathematical techniques that allow for the generation of random numbers without revealing their source. For example, in RSA encryption, the public and private keys are generated such that they generate "random" values, making it difficult for an attacker to determine those values. Similarly, in symmetric-key cryptography, there is a technique called
