👉 In cryptography, concealment refers to the process of hiding or concealing information or data from unauthorized access. This can be achieved through various techniques such as encryption, hashing, and digital signatures. For example, in a secure communication protocol like SSL/TLS (Transport Layer Security), the recipient will not be able to determine the original sender's identity without additional verification steps. This is done by using public key cryptography or by having the sender encrypt the data with their private key before sending it over the network
