What are Digital Signatures

This course introduces the concept of digital signatures and their role in securing communication and transactions.

You will explore:

• The background of digital signatures and how they build on asymmetric cryptography
• How private and public keys work together for signing and verification
• Why digital signatures are critical in online commerce, governance, and communication
• The key properties that make them trustworthy: authenticity, integrity, and non-repudiation

By the end of the course, learners will:

• Understand what digital signatures are and how they function
• Recognize their importance in real-world applications
• Be familiar with the essential protections digital signatures provide

This course is designed for beginners. No prior cryptography knowledge is required — just curiosity about how trust is built in the digital age.
