What are encryption keys?

Encryption keys are crucial tools used for encoding and decoding data, ensuring its confidentiality and integrity. They are pivotal in various encryption algorithms, including one- time pads where they play a vital role. In one-time pads, keys are random strings as long as the message itself and are used only once for encryption and decryption. This method provides perfect secrecy, demonstrating the importance of encryption keys not only in standard encryption schemes but also in absolute secure communications enabled by one-time pads. Like the data they safeguard, encryption keys demand stringent protection to maintain the security of the encrypted information.
