   1 day ago · Symmetric-key cryptography, where a single key is used for encryption and decryption. 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).

   What is a symmetric cipher?

   • This method of encryption involves using a cryptographic key and algorithm to transform plaintext into ciphertext, ensuring the confidentiality and integrity of information. A symmetric key and algorithm encrypt and decrypt data blocks at the core of a block cipher’s operation.

   What are asymmetric ciphers?

   • These ciphers use asymmetric algorithms which use one key to encrypt data and a different key to decrypt ciphers. Typically, those two keys are called public and private keys, as is the case with RSA encryption. The public key is used to encrypt data, and the private key is used to decrypt data.
