encryption-service

Framework: angular

📦 Installation / Import

import { EncryptionService } from 'universe-code/angular';

⚙️ Step 1: Create Encryption Service

Create file: src/app/services/encryption.service.ts

import { CONFIG } from 'config';
import { EncryptionService } from 'universe-code/angular';

export const encryptionService = new EncryptionService(
  CONFIG.encryptionKey // your encryption key
);

📥 Step 2: Use Encryption Service in Any Component / Service

import { encryptionService } from 'src/app/services/encryption.service';

🔑 Available Functions

1️⃣ Encrypt Data (High Security)

Use this for user data, credentials, sensitive information.

const data = { userId: 123, email: 'user@example.com' };
const encrypted = await encryptionService.encryption(data);

// Returns: { iv: "...", payload: "..." }

✅ Uses 100,000 iterations (more secure)

2️⃣ Decrypt Data (Matching encryption())

const encrypted = { iv: "...", payload: "..." };
const decrypted = await encryptionService.decryption(encrypted);

// Returns: { userId: 123, email: 'user@example.com' }

⚠️ Rule: encryption() → decryption()

3️⃣ Encrypt Data (Fast Mode)

Best for API responses or less sensitive data.

const data = { status: 'success', token: 'xyz789' };
const encrypted = await encryptionService.encryption1(data);

// Returns: { iv: "...", payload: "..." }

✅ Uses 50,000 iterations (faster)

4️⃣ Decrypt Data (Matching `encryption1()`)

const encrypted = { iv: "...", payload: "..." };
const decrypted = await encryptionService.decryption1(encrypted);

// Returns: { status: 'success', token: 'xyz789' }

⚠️ Rule: encryption1() → decryption1()

5️⃣ Decrypt API Response (`iv###payload` format)

Use this when API returns data in "iv###payload" format.

const apiResponse = "dGVzdGl2###ZW5jcnlwdGVkUGF5bG9hZA==";
const decrypted = await encryptionService.decrptApiResponse(apiResponse);

// Returns: decrypted object or null if format is invalid

📌 Returns

✅ Decrypted object (if format is valid)
❌ null (if format is invalid)

🧠 Which Method Should I Use?

Method	Use Case
`encryption()`	General data encryption (user data, sensitive info)
`decryption()`	Decrypt data encrypted with `encryption()`
`encryption1()`	API responses, faster encryption
`decryption1()`	Decrypt data encrypted with `encryption1()`
`decrptApiResponse()`	Decrypt API responses in `"iv###payload"` format

⭐ Key Points (Must Read)

encryption() uses 100,000 iterations (more secure)
encryption1() uses 50,000 iterations (faster)
Always use matching encrypt/decrypt pair
decrptApiResponse() only works with "iv###payload" format
Requires async/await or Promise handling
