namely symmetric crypto systems. Topics covered are pseudorandom functions, number generators, stream ciphers, block ciphers, hash functions, message authentication functions, and block cipher ...

the texture for the command block isn’t completely symmetric or perfect! Once you spot this issue, you'll find it hard to look at command blocks with your old, naïve eyes again 😭 To solve this ...

To understand what this proposal is, and why it is important, we need to dig a bit deeper into what a block cipher is, and the history of the AES algorithm. A block cipher is a mechanism to ...

Verilog implementation of the symmetric block cipher AES (Advanced Encryption Standard) as specified in NIST FIPS 197. This implementation supports 128 and 256 bit keys.
