+# Devlog - 2025-12-12
+
+## 🚀 What I Did
+
+- Codewars.
+- Random Password generator(using random function, maps, and crypto)
+
+## 🧠 What I Learned
+
+- `Uint32Array` = array of big random numbers (0 to 4.29 billion).
+- `Uint8Array` gives only 0–255 (less randomness).
+- `Uint16Array` gives 0–65,535.
+
+### Cryptographically random values
+
+- Comes from OS-level secure random generator(Linux /dev/urandom, Windows Cryptographic Provider, macOS SecureRandom)
+- non-predictable.
+- high entropy.
+- designed specifically for passwords, keys, salts, tokens.
+- It follows NIST SP 800-90 standards used in cryptography.
+
+```javascript
+crypto.getRandomValues(arr);
+```
+
+## 🔥 What's Next
+
+- FCC.
+- Codewars.
+- Theory(Dom).
