Top reviews from Basic Cryptography and Programming with Crypto API

By LBApr 2nd 2018

The course content is excellent. It would be much better if some errors (like misspelled words, improper capitalization etc) would be corrected

By NHSep 10th 2019

This Course is good but difficult for learner. To provide better knowledge as expert level course should be extended.
