ECDSA- creating a private key and verifying the signature with the signed data through an API.

Follow the below steps to execute the code

• export FLASK_APP=bitbucket
• export FLASK_ENV=development
• flask run

make sure that you are in the gitlab directory, to run bitbucket directory as a package

**********************************PycharmProjects/github/gitlab$ ***********************************PycharmProjects/github/gitlab$ export FLASK_APP=bitbucket **********************************PycharmProjects/github/gitlab$ export FLASK_ENV=development **********************************PycharmProjects/github/gitlab$ flask run

you would see something like below,

 * Serving Flask app 'bitbucket' (lazy loading)
 * Environment: development
 * Debug mode: on
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 740-216-853

1. The op should be one of the seven arithmetic operators for python.

2.The server must verify the data field ECDSA signature

3. The API does both.
