See more at key Examples of symmetric keysymmetric key Encryption algorithms which use the same key for both encryption and decryption are known as symmetrickey algorithms. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Pseudorandom generators may also be used to construct symmetrickey cryptosystems, where a large number of messages can be safely encrypted under the same key. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Such systems almost always use symmetrickey cryptographic algorithms. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. One type of encryption, secret key or symmetrickey, relies on diffusion and confusion, which is modeled well by chaos theory. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. There is a physical argument that a 128-bit symmetrickey is computationally secure against brute-force attack. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The recipient then decrypts the public key message to recover the symmetrickey. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. To transmit an encrypted key to a device which possesses the symmetrickey necessary to decrypt that key requires roughly 256 bits as well. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Currently, key lengths of 128 bits (for symmetrickey algorithms) and 1024 bits (for public-key algorithms) are common. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Since longer symmetric keys require exponentially more work to brute force search, a sufficiently long symmetrickey makes this line of attack impractical. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This key can then be used to encrypt subsequent communications using a symmetrickey cipher. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It then uses the symmetrickey to decrypt the file. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Symmetrickey ciphers (also referred to as secret key ciphers) are called such because the same key is used for both encryption and decryption. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. As the symmetrickey is generally short, padding is required for full security and proofs of security for padding schemes are often less than complete. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The message is encrypted using a symmetric encryption algorithm, which requires a symmetrickey. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It is clear that symmetrickey systems offer the smallest key sizes for post quantum cryptography.
