The Vigenere cipher is an encryption method that uses a series of interwoven Ceaser ciphers and a keyword to encrypt text. The difference between this cipher and the Ceaser cipher is the tabular interwoven Ceaser cipher and the keyword.
Multiple keywords can be used in the Vigenere cipher. The use of this keyword makes the brute-force decipher algorithm unreliable for decoding text encrypted with it.
What do you mean pieces? Like Laptop components? If so then motherboard,ram,cpu, and psu for a basic laptop so 4 I guess (5 if you want to include a gpu).
