How It Works

Secure File Sharing
Made Simple

Upload, encrypt, and share your files with military-grade security. Here's exactly how Enfileup protects your data.

File Lifecycle

From upload to download, every step is secured

Upload Files

Select and upload your files through our secure interface. Multiple files and folders supported.

Max 2GB per upload

Auto Encryption

Files are automatically encrypted using AES-256 encryption. Media files (images, videos, audio) remain unencrypted for preview.

AES-256 Standard

Secure Storage

Encrypted files are stored in our secure servers with unique URLs and optional expiration dates.

Auto expiration

Share Securely

Get a unique shareable URL. Recipients can download files with automatic decryption on-the-fly.

Unique URL

Encryption Details

Military-Grade
Encryption

We use AES-256 encryption, the same standard used by governments and banks worldwide. Your files are encrypted before storage and decrypted only when downloaded.

Zero-Knowledge Architecture

We never store your encryption keys. Only you have access to your files.

End-to-End Protection

Files are encrypted in transit and at rest. Complete security through the entire journey.

Optional Password Protection

Add an extra layer with password protection for your ZIP downloads.

// Encryption Process

function encryptFile($file) {

if (!isSafeBinary($file)) {

// Text files, documents encrypted

$encrypted = AES256::encrypt(

$file,

$key

);

} else {

// Media files: images, videos, audio

// Stored unencrypted for preview

$encrypted = $file;

}

return $encrypted;

}

Code Sharing

Secure Pastebin Alternative

Share code snippets and text with server-side syntax highlighting, end-to-end encryption, and burn-after-reading support

Syntax Highlighting

Server-side highlighting for 20+ languages including PHP, JavaScript, Python, and more

Burn After Reading

Self-destruct pastes after first view - perfect for sharing sensitive credentials

Encrypted Storage

All pastes are encrypted with AES-256-CBC - even we can't read your code

Download & Raw View

Download pastes with proper file extensions or view raw content for easy copying
