Part $1$

Use a two$-$stage transposition technique to encrypt the following message using the key "Decrypt". Ignore the comma and the period in the message.

Message: "The Transposition cipher technique works by permuting the letters of the plaintext. It is not very secure$,$ but it is great for learning about cryptography."

Is it possible to decrypt the message with a different key? Justify your answer.

Do you agree with the statement of the message? Why or why not? Give at least two examples that support your view.

Part $2$

Research and provide a detailed meaning for at least three techniques in which encryption algorithms can produce ciphertext. Pick at least $3$ from the cipher list below:

Monoialphabetic

Steganographic

Polyalphabetic

Polygraphic

Route transposition

Columnar Transposition

Synchronous Stream

Asynchronous Stream
