Cryptography Fundamentals
The essentials of encryption, hashing, signatures and keys — what they protect, where they are used and how they fail in practice.
Who it's for
Security, IT and development professionals who need a sound working understanding of cryptography.
Learning outcomes
- Distinguish symmetric and asymmetric encryption, hashing and signatures
- Understand certificates, PKI and TLS at a practical level
- Recognise weak key management and outdated algorithms
