Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). This was the only kind of encryption publicly known until June 1976. Symmetric key ciphers are implemented as either block ciphers or stream ciphers. … WebCryptography is a continually evolving field that drives research and innovation.

If you use one key to encrypt and decrypt data, then it means you’re using symmetric encryption. But if you’re using two separate keys — one to encrypt data and the other to decrypt it — then you’re using asymmetric encryption (public key encryption). cynthia hicks lottery

"WebIn cryptography, the RSA problem summarizes the task of performing an RSA private-key operation given only the public key. The RSA algorithm raises a message to an exponent, modulo a composite number N whose factors are not known. Thus, the task can be neatly described as finding the eth roots of an arbitrary number, modulo N. " - Cryptogrophy what is composite key

WebIf the authenticator is encrypted with the sender's private key, it serves as a signature that verifies origin, content, and sequencing. TRUE A trap-door one-way function is easy to calculate in one direction and infeasible to calculate in the other direction unless certain additional information is known. TRUE WebThis is also called public key cryptography, because one of the keys can be given to anyone. The other key must be kept private. The other key must be kept private. The algorithm is based on the fact that finding the factors of a large composite number is difficult: when the factors are prime numbers , the problem is called prime factorization .
