Encryption and decryption stages
Posted: Wed Feb 12, 2025 6:42 am
Keys are used to encrypt and decrypt data. The key size the number of bits in the key determines how secure the encryption is. AES supports 128-bit, 192-bit, and 256-bit encryption keys. 256-bit keys provide the most security and are used by intelligence agencies to encrypt their secrets, while 192-bit and 128-bit AES encryption is used for things like banking and secure web browsing.
AES is a form of symmetric-key encryption as opposed to asymmetric-key encryption, meaning that the same key is used to both encrypt and decrypt data.
The steps to encrypt data using the AES standard guatemala telegram data are as follows:
Based on the initial encryption key usually a password provided by the user, a series of "round keys" are generated. These will be used in each round of encryption.
The encryption process begins by combining the encryption key with the data to be encrypted using the XOR operation.
The data is encrypted in additional "rounds" using a substitution-permutation network encryption algorithm. This step is repeated depending on the result of the previous round, depending on the key size. It is repeated 10 times for 128-bit encryption, 12 times for 192-bit encryption, and 14 times for 256-bit AES encryption.
The final round of encryption is performed using the "last round key", resulting in the final encrypted message.
