Hi Danilo,

The MIFARE Classic has usually one byte commands and reading and writing data blocks contains all 16 bytes of a block.

What you published in your post is obviously required for your reader/driver infrastructure. Usually the reader manufacturer define the APDU sequences you have to use for communication. The MIFARE Classic uses an own protocol and the encryption is usually handled in the NFC reader frontend IC. All reader interface I know allow to save a key with a separate command inside of the reader and refer to it for all following commands.
