To verify how the system works, simply type python main.py -h and the program will show you the options. For the majority of them, there are default values set to files in 'key' folder.

All you absolyutly have to decide is the operation. If you want a full test routine, try:

python main.py -op 1

---

In any case, here are the options transcriped:

options:

-h, --help show this help message and exit

--keysize KEYSIZE, -key KEYSIZE initial size of rsa modulus n

--prv_key_path, -prv Path for private key to be used

--pub_key_path, -pub Path for public key to be used

--encript_path, -enc Path to message to be encripted

--store_path, -str Path to signed message to be stored

--decript_path, -dec Path to message to be decripted

--output_path, -out Path to save the decripted message

--key_setup, -set 1 for key generating and 0 for key importing

--operation {1,2,3,4,5}, -op {1,2,3,4,5}

1 for full test
2 for encription
3 for decription
4 for signing
5 for verifying signature
