Is this encryption tool secure?

Yes, this tool uses industry-standard encryption algorithms like AES-256, which is used by governments and financial institutions worldwide. All encryption happens directly in your browser—your data never leaves your device. The security of your encrypted data depends primarily on your password strength, so be sure to use strong, unique passwords.

Which encryption algorithm should I use?

For most purposes, AES-256 is the recommended choice. It offers an excellent combination of security, performance, and widespread adoption. It's considered secure against brute force attacks even with quantum computing. Other algorithms like Triple DES or Rabbit might be suitable for specific compatibility needs, while DES and RC4 are only included for legacy purposes and should be avoided for sensitive data.

What happens if I forget my encryption password?

If you forget your encryption password, there is no way to recover your encrypted data. This is a fundamental security feature of proper encryption—there are no 'backdoors' or password recovery methods. This is why it's crucial to store your encryption passwords securely, such as in a password manager, while ensuring you don't lose access to the password manager itself.

What is Base64 encoding and why is it used with encryption?

Base64 is an encoding scheme that converts binary data into a text format using 64 printable ASCII characters. It's often used with encryption because encryption typically produces binary data that may contain non-printable characters. By applying Base64 encoding to the encrypted result, we ensure the output contains only printable characters, making it easier to copy, paste, store in databases, or transmit through text-based channels like email or chat.

File Encryption

Algorithms

Note: File encryption is performed entirely in your browser. No files are uploaded to any server. Large files may take some time to process.

Operation:

Algorithm:

Password / Secret Key:

Drag and drop file here, or click to select file

Important: Remember your password! If you lose it, you won't be able to decrypt your file. There is no way to recover encrypted files without the original password.

Encryption Algorithm Comparison

Algorithm	Security Level	Speed	Key Size	Best For
AES-256	Very High	Fast	256 bits	General purpose encryption, recommended for most uses
DES	Low	Fast	56 bits	Legacy systems, not recommended for sensitive data
Triple DES	Medium	Slow	168 bits	Legacy systems requiring more security than DES
Rabbit	Medium-High	Very Fast	128 bits	Streaming data, applications requiring high speed
RC4	Very Low	Very Fast	40-2048 bits	Not recommended for any new applications

Security Recommendation: AES-256 is the recommended algorithm for most use cases. It provides a good balance of security and performance and is widely recognized as a secure standard.

About Encryption & Decryption

Encryption is the process of encoding information so that only authorized parties can access it. Encryption transforms readable data (plaintext) into an unreadable format (ciphertext) using mathematical algorithms and keys.

Important Security Note: This tool performs client-side encryption in your browser. While this ensures your data never leaves your device, the security of your encrypted data ultimately depends on the strength of your password. Always use strong, unique passwords for sensitive information.

Key Features of This Tool

Client-Side Processing

All encryption and decryption happens locally in your browser. Your data never gets sent to any server, ensuring maximum privacy.

Multiple Algorithms

Choose from several industry-standard encryption algorithms including AES-256, DES, Triple DES, Rabbit, and RC4.

Text & File Encryption

Encrypt both text messages and files using the same secure algorithms, with support for files up to browser memory limits.

Base64 Encoding

Automatically converts binary encrypted data to Base64 for easy copying, sharing, and storage in text formats.

Common Uses for Encryption

Secure Communication: Encrypt sensitive messages before sending them through potentially insecure channels.
Data Protection: Secure personal information, financial details, or business data stored on computers or in the cloud.
Password Storage: Store passwords and credentials in an encrypted format for additional security.
Legal Compliance: Meet data protection regulations by encrypting personally identifiable information (PII).
File Security: Protect sensitive documents, photos, or other files from unauthorized access.

Best Practices for Encryption

Use Strong Passwords: The security of your encrypted data depends heavily on your password strength. Use long, complex passwords with a mix of letters, numbers, and symbols.
Don't Reuse Encryption Passwords: Use unique passwords for different encrypted data to prevent compromising multiple datasets if one password is exposed.
Select Appropriate Algorithms: Use AES-256 for most purposes. Only use other algorithms if you have specific compatibility requirements.
Keep Keys Secure: Store your encryption passwords or keys securely. Consider using a password manager.
Backup Encrypted Data: Always maintain backups of your encrypted data and ensure you have a secure record of the passwords needed to decrypt them.

Technical Implementation

This tool uses the CryptoJS library, a collection of standard and secure cryptographic algorithms implemented in JavaScript. Here's a simple example of AES encryption in JavaScript:

// Encrypt
var ciphertext = CryptoJS.AES.encrypt('My secret message', 'secret key 123').toString();

// Decrypt
var bytes  = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');
var originalText = bytes.toString(CryptoJS.enc.Utf8);

console.log(originalText); // 'My secret message'
