Episode notes
Digital Identity Is More Than An Email
- Digital identity is a collection of persistent, provable, and portable identifiers rather than a single tag like a cookie.
- Email works well as an alias, but decentralized IDs and PKI remove the need to 'phone home' to centralized providers.
PKI Lets You Prove Identity Without 'Phoning Home'
- Public key infrastructure lets identities be verified bilaterally without contacting a central provider like Google.
- A DID paired with cryptographic signatures makes authentication persistent and independent.
Sign Messages With Hashing Then Private Key
- Use hashing plus private-key encryption to create signatures that verify authenticity and integrity.
- Recompute the hash and decrypt the signature with the public key to confirm the signer and unchanged content.
