Cryptography Course

This course discusses how the poor use of cryptography can leave an application vulnerable to attack and how it can be exploited, as well as potential mitigations.

40 minutes

Course description

Cryptography is a very useful tool. However, it can also be very fragile. A small error in design or implementation can destroy any benefits of using encryption in an application. This course describes some of the common errors that developers make when using cryptography and how to remediate them.
