Write two simple programs using OpenSSL library on Linux.

1) Create a simple program that encrypts/decrypts a file with AES-128 in CBC
mode (using OpenSSL library) with
  fixed key: 00112233445566778899aabbccddeeff (in hexa) and
  fixed IV:  00000000000000000000000000000008 (in hexa).

Hints:
 - file name can be hardcoded (you can use memory buffer holding the whole file content)
 - to access file you can use OpenSSL BIO functions or any other functions

Deadline: November 8, 2017, maximum is 5 points.


2) Create a simple program that generates 4096 bit RSA key with public exponent 17
and prints private and public output to the screen.

Hints:
 - Use RSA_generate_key_ex() function.
 - Use PEM_read/write_PrivateKey or BIO based PEM_read/write_bio_PrivateKey
   (the same for public key).

Deadline: November 8, 2017, maximum is 5 points.

Your submitted archive should contain *two* C programs above.

The source code must be compilable on the provided virtual machine (Linux Fedora)
or on aisa server.
