Take a sample of Plain text, encrypt this plaintext step by step using AES, you must show each step how it has been done with all tables and codes, till you generate the Ciphertext. the reverse your work step by step until you generate the Plaintext
Your plaintext is:
“Here you can encrypt a block of bytes with a key using the popular Advanced Encryption Standard cipher” . All the internal steps of the computation are shown, which can be helpful for anyone debugging their own AES implementation. In each of the 10/12/14 rounds, the sub-steps of SubBytes, ShiftRows, MixColumns, AddRoundKey, and key schedule are shown”
Hello
I have vast knowledge on the topic which can help me get the work done perfectly and on time. I am looking forward to working with you.

I've done similar projects before. I've implemented DES in C++ and Python from scratch. I've implemented X509 certificates, Elgamal digital signature algorithm, RSA algorithm, etc.
