Brilliant post on prompt caching!

This is one of the most effective and underutilized techniques for reducing LLM usage costs.

Software development is complex, and the fancy names don't help.

Hashing vs. Encryption vs. Encoding

1. Hashing

This is a one-way process used for data integrity verification.

When you hash data, you get a unique string representing the original data.

It's a one-way street; once you hash something, you can't get the original data back from the hash.

This property makes it perfect for verifying if someone altered the data.

If even one-bit changes in the original data, the hash changes dramatically.

2. Encryption

This is the real deal when it comes to data security.

It uses algorithms and keys to transform readable data (plaintext) into an unreadable format (ciphertext).

Only those with the correct key can unlock (decrypt) the data and read it.

This process is reversible, unlike hashing.

Encryption is critical for protecting sensitive data from unauthorized access.

3. Encoding

This is all about data representation.

It converts data from one format to another, making it easier to interpret and display.

Common formats:
- Base64
- UTF-8
- ASCII

Encoding does NOT provide security! It's for data transmission and storage convenience.

One common use of hashing is for secure password storage.

When you create an account or set a password, the system hashes and stores the password in the database.

During login, the system hashes the provided password and compares it to the stored hash without revealing the password.

I hope this helps some young engineers out there.

Keep coding!

Understanding OAuth

OAuth is an open standard that allows users to grant limited access to their data on one site to other sites or applications without exposing their passwords. It has become the backbone of secure authorization across the web and mobile apps.

The OAuth ecosystem

OAuth connects three main players:

- The User who wants to grant access to their data without sharing login credentials
- The Server that hosts the user's data and provides access tokens
- The Identity Provider (IdP) that authenticates the user's identity and issues tokens

How OAuth works

When a user tries to access their data through a third-party app, they are redirected to log in through the IdP. The IdP sends an access token to the app, which presents it to the server. Recognizing the valid token, the server grants access.

The OAuth flows

OAuth 2.0 defines four flows for obtaining authorization tokens:

- Authorization Code Flow - for server-side applications
- Client Credentials Flow - when the app is the resource owner
- Implicit Code Flow - not secure and no longer recommended
- Resource Owner Flow - for trusted apps using owner credentials

Key benefits

- Enhances user experience by eliminating multiple passwords
- Allows secure data access across platforms using tokens
- Balances accessibility and security

OAuth 2.0 has become the standard for authorization. It enables secure, convenient data sharing while protecting user accounts.

This is for the folks who are new to the industry and feel crushed after failed interviews.

Kyle is the author of the "You Don't Know JS" books, and he also got rejected for "not knowing enough JS".

This is your reminder that every developer fails interviews, no matter how experienced that developer is.
