COMS W4181 - HW1 - cstore secure archive Author: Andrei Oprisan [email protected]

Archive design:

1. files counter
2. files 1...n headers
3. files 1...n contents
4. hmac

cstore implementation utilizes AES CBC with PKCS7 for padding contents to a block size of 16. The pseudorandom number generator at /dev/random is used with a 10k iteration SHA-256 as the key for file encryption. HMAC values are regenerated on add and delete actions based on user archive and password values.

To build the app, run make

To clean up the build, run make clean
