This will create a submission.zip file in the folder where you executed the command.. Local Setup (backup) If you’re having trouble with the above, try downloading this Python script and running it on your local computer (e.g. python3 submit.py)..

Project 3 HINTS Is magic_quotes_gpc enabled on the web server? Yes, it's enabled. escapes single quotes, double quotes, and backslashes in GET and POST data by prepending a backslash. This feature makes it slightly harder to write websites 3. User Struct corruption: Because each user struct is Encrypted and Signed with Keys deterministically created based on the user’s username and password, each user is stored in the Data Store with Integrity and Authenticity. If an attacker somehow gained access to the Data Store and and tampered with a User Struct, upon calling GetUser()

The backend for this project exclusively uses single quotes for SQL queries. It is possible to select constants in SQL rather than selecting column names. For example, SELECT 1, 'foo', 'evan' will return a single row with 3 columns, with values of 1, 'foo' and 'evan'. You may find this useful if you can guess the format of the rows being ... $ ssh -t [email protected] \~cs161/proj1/start Replace XXXwith the last three letters of your instructional account, and YYwith the number of a hive machine (1-20).

It took me three full days to complete this extremely difficult project, with over 3 thousand lines of code. Such an intensive development experience can greatly enhance your ability to design and implement a secure system.
