Elliptic Curve Cryptography

If you’ve ever created an RSA-based SSH key, you might have been surprised by the size of the key it generated. Elliptic Curve Cryptography (ECC), on the other hand, offers much shorter keys while maintaining the same level of security. Since its introduction, ECC has steadily gained popularity and has increasingly replaced RSA for both confidentiality (encryption) and non-repudiation (digital signatures).

The following blog posts present the internals of ECC. On my personal GitHub page, you will find the source code for an elliptic curve implementation for cryptography, along with illustrations used to describe the topic.
