Cryptography in Python

             Python for Cryptography

Nowadays, the development of secure
applications, the secure encryption and decryption of data as well as protecting the users privacy in general are essential to many software projects. However, the
large number of different cryptographic algorithms as well as their complexity pose a challenge to many developers. In this course, you will learn the concepts of cryptography such as symmetric
encryption, asymmetric encryption,
digital signatures and certificates and
common attacks on cryptographic systems.
You are taught both the underlying theory
as well as python example implementations
in order for you to obtain a thorough
understanding of cryptography and enhance
 your python programming skills. This seminar
 can be run as an in-house training course as
well, e.g., in England, France, Switzerland,
Austria, Italy, Netherland, Luxembourg, Belgium,
or Germany.

Target Group:
This course is intended for developers with basic python or programming background. The participants acquire the necessary knowledge to create encryption schemes and also complementary python skills for securing their applications.

Content:
The aim of this course is two folds. One is to enhance one’s python skills and add a fundamental aspect, i.e., cryptography, to their existing skill set. The other is to enhance one’s understanding of cryptography with the help of both theoretical and practical lessons. Once you complete this course, you are able to create your custom cryptographic schemes and also make use of these schemes in your application development.
