Symmetric Encryption

Symmetric encryption is a cryptographic technique where the same key is used for both the encryption and decryption of data. The process involves converting plaintext (original data) into ciphertext (encrypted data) using an encryption algorithm and a secret key. To decrypt the ciphertext and retrieve the original data, the same key is applied in reverse through a decryption algorithm. Symmetric encryption is efficient and fast, making it suitable for securing data at rest or during transmission. However, securely sharing and managing the secret key among parties is crucial to maintain the confidentiality and integrity of the encrypted information.
