= Key schedule
{wiki=Key_schedule}
The term "key schedule" typically refers to the process used in cryptographic algorithms, particularly symmetric encryption, to generate a series of round keys from a given secret key. This is an essential step in many block cipher algorithms, such as AES (Advanced Encryption Standard) and DES (Data Encryption Standard). \#\#\# Key Schedule Process 1. **Input Key**: The process starts with a single secret key, which may be of fixed length (e.g.
