+# About
+
+This is the Cryptography homework 3.
+
+# Usage
+
+## Installation
+
+Please install `pycryptodome` using Python 3.10.
+
+## Part 1
+
+First run `alice.py` and input the message.
+Run `bob.py` to decrypt the message.
+
+## Part 2
+
+Run `bob.py` to generate bob's public and private keys.
+Run `alice.py` and enter a message.
+Run `bob.py` to decrypt the message.
+
+## Part 3
+
+Run `speed-test.py` or speed-test-nokey.py`.
+
+The difference between the two is that nokey doesn't generate a new key for each encryption and decryption.
