128-bit AES calculation
What is the maximum amount of time that it would take a computer that can test 1000 billion (1012) keys per second to carry out a brute-force attack on a file encrypted using 128-bit AES? Give your answer in years, using scientific notation, correct to 2 significant figures.
From the question above, Could you please explain the step by step of the following:
2^128 / 10^12 x 3.2 x 10^7 = 2^128 / 10^18 x 32 (how the 10^18 and 32 appeared as a result?)
Sorry if I am too stupid, but I just want to understand the calculation.
Thank you!

Brute force attack
What is the maximum amount of time that it would take a computer that can test 1000 billion (1012) keys per second to carry out a brute-force attack on a file encrypted using 128-bit AES? Give your answer in years, using scientific notation, correct to 2 significant figures.
Maximum time to 1000 billion (10^12) keys carries a brute force attack.
How long will take for a computer that can test 1000 billion (10^12) keys per second, to carry out a brute force attack in an encrypted file using 128-bit -AES. Your answer should be in years using scientific notation correct to 2 significant figures and you may assume that "one year" is 3.2 x 10^7 seconds.

Implement in Go language AES encryption mode CBC with providing the packages name for Go language. You can implement AES-ECB Mode (the basic AES) from crypto/aes package and crypto/cipher.Block. You can also get the SHA-256 hash function from crypto/sha256. You can get the secure random numbers generator from crypto/rand package. However, the you will implement both CBC mode and HMAC from scratch. You are NOT allowed to use any libraries or packages to implement these two things for you. You...
