Episode 16 — Understand Asymmetric Crypto, Key Pairs, and Digital Signatures for Trust
Asymmetric cryptography solves the key distribution problem through the use of mathematically linked public and private key pairs, a concept we explore in-depth in this episode. We explain how data encrypted with a public key can only be decrypted by the corresponding private key, enabling secure communication between parties who have never met. The discussion expands into digital signatures, which provide both integrity and non-repudiation by proving that a message was sent by a specific identity and was not modified in transit. You will learn about foundational algorithms like RSA and Elliptic Curve Cryptography (ECC), which power the modern web and secure email communications. The GISF blueprint requires a solid grasp of how public keys are shared openly while private keys must be protected with the highest level of administrative care. This understanding is the prerequisite for mastering the trust chains and digital certificates explored in future sessions.
