How can I use cryptography for API authentication?

You can use cryptography to secure API authentication by implementing methods like OAuth, JWT, or HMAC.

What is OAuth and how does it work?

OAuth is an open standard for access delegation, allowing users to grant third-party access to their resources without sharing credentials.

Can you explain JWT and its benefits?

JWT, or JSON Web Token, is a compact token format that securely transmits information between parties. It’s stateless and can be verified easily.

What is HMAC and when should I use it?

HMAC, or Hash-based Message Authentication Code, is used to verify data integrity and authenticity. Use it when you need to ensure that a message has not been altered.
