HOW SECURE IS SAZUMI CLOUD?

MILITARY-GRADE ENCRYPTION

Every file you upload is encrypted with AES-256 - the same encryption standard used by governments and military organizations worldwide. Your files are encrypted before they ever leave your browser.

THE ENCRYPTION PROCESS:

  1. 1

    File Selection

    Your file is processed entirely within your browser

  2. 2

    Key Generation

    A unique random 256-bit encryption key is generated for each file

  3. 3

    AES-256 Encryption

    Your file is encrypted using the generated key

  4. 4

    Secure Upload

    The encrypted file is sent to our servers via HTTPS

  5. 5

    Secure Storage

    The encrypted file is stored on our secure cloud infrastructure

SEE THE ENCRYPTION IN ACTION:

// Original file data (simplified example)
const fileData = "Hello, this is my sensitive file content";

// Generate a random 256-bit key (32 bytes)
const key = crypto.randomBytes(32);
// 3a4f8e2c1d9b7a5e6f0c3a2b1d8e9f7a6b5c4d3e2f1a0b9c8d7e6f5a4b3c2d1

// Generate a random initialization vector (16 bytes)
const iv = crypto.randomBytes(16);
// 7b8a9c6d5e4f3a2b1c0d9e8f7a6b5c4d

// Create cipher with AES-256-CBC algorithm
const cipher = crypto.createCipheriv('aes-256-cbc', key, iv);

// Encrypt the data
let encrypted = cipher.update(fileData);
encrypted = Buffer.concat([encrypted, cipher.final()]);
// Encrypted result: 8f7a6b5c4d3e2f1a0b9c8d7e6f5a4b3c2d1e0f9...

"Trying to view our encrypted files without the key is like trying to read a book in the dark while wearing sunglasses... underwater... and the book is written in invisible ink."

FUN FACT ABOUT AES-256

Breaking AES-256 with current technology would take billions of years. By that time, the universe might have ended, humanity could have evolved into energy beings, and someone will have finally figured out why the USB never goes in right on the first try.

STILL NOT CONVINCED?

Here's what happens if someone tries to intercept your upload:

Hacker intercepts data:

0x8f0x7a0x6b0x5c0x4d0x3e0x2f0x1a0x0b0x9c0x8d0x7e0x6f0x5a0x4b0x3c...

Hacker's reaction:

"What is this garbage? I can't read anything! Where's the cat photo I was trying to steal?!"

Time needed to crack AES-256:

149 TRILLION YEARS

(using all computers on Earth combined)
