Symmetric vs. Asymmetric Encryption: How They Work

WebJan 5, 2024 · 1. Symmetric cryptography. Symmetric cryptography involves encrypting and decrypting data using the same key, which is only known to the sender and receiver of the message. Due to this reason, it is also known as private-key cryptography. The most important thing in this form of cryptography is the key. Web1.3 The key distribution problem. Traditionally, symmetric encryption suffered one enormous shortcoming – it was necessary for either the sender or the recipient to create a key and then send it to the other party. While the key was in transit, it could be stolen or copied by a third party who would then be able to decrypt any ciphertexts ... Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys. The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private informatio… galley kitchen minimum width
