Course 411: Using cryptographic tools in the GC


This course will provide participants with practical hands-on training on protecting file confidentiality and integrity through encryption and digital signatures. This course will also enable participants to apply volume encryption to data at rest, encrypt and digitally sign email, validate the integrity of downloaded software, enhance privacy and security by using a VPN, and encrypt text, voice, and video messages. The instructor-led portion of the course addresses tools and practices in a GC context and require the use of a GC-provided computer during the training. Tools and practices that apply to personal information and infrastructure are addressed in the handbook that will be made available prior to the training.


The objectives of this course are to ensure that upon successful completion, the participant will be able to:

  • use a password manager
  • encrypt and digitally sign data
  • encrypt and digitally sign emails
  • verify integrity of internet components

Target audience

Employees working within the Government of Canada.


Participants must successfully complete course 410 – Cryptographic security in the GC prior to attending this course.
