How It Works

1

Enter Your Text

Type or paste the text you want to encrypt or decrypt into the text area.

2

Choose Algorithm

Select from AES-256 (military-grade), Base64 (encoding), ROT13 (simple substitution), or Caesar cipher (shift cipher).

3

Set Encryption Key

For AES-256, enter a strong password. For Caesar cipher, adjust the shift amount. Then click Encrypt or Decrypt.

Frequently Asked Questions

What encryption algorithms are available?

We offer four encryption methods: AES-256 (military-grade encryption with PBKDF2 key derivation), Base64 (encoding for binary data), ROT13 (simple letter substitution cipher), and Caesar cipher (shift cipher with customizable shift amount). AES-256 is recommended for sensitive data.

Is AES-256 encryption secure?

Yes, AES-256 is military-grade encryption used by governments and security professionals worldwide. Our implementation uses AES-GCM (Galois/Counter Mode) with PBKDF2 key derivation (100,000 iterations) for maximum security. All encryption happens locally in your browser - your data never leaves your device.

Can I decrypt text encrypted with this tool?

Yes! For AES-256, you need the same encryption key that was used to encrypt the text. For Base64, ROT13, and Caesar cipher, decryption is automatic. Make sure to save your encryption keys securely - if you lose the key, AES-encrypted data cannot be recovered.

What is the difference between encryption and encoding?

Encryption (AES) transforms data to keep it secret and requires a key to decrypt. Encoding (Base64) transforms data for transmission or storage but is not secret - anyone can decode it. ROT13 and Caesar are simple ciphers that provide basic obfuscation but are not secure for sensitive information.

Is my data safe? Is it sent to a server?

Your data is completely safe! All encryption and decryption happens locally in your browser using the Web Crypto API. Nothing is ever sent to our servers. Your text and keys never leave your device, ensuring complete privacy and security.

About Text Encryptor

Text Encryptor is a powerful security tool for encrypting and decrypting text using multiple encryption algorithms and encoding methods. AES-256 encryption provides military-grade security with AES-GCM (Galois/Counter Mode) and PBKDF2 key derivation using 100,000 iterations, making it virtually impossible to crack without the encryption key. All encryption happens locally in your browser using the Web Crypto API, ensuring your sensitive data never leaves your device and is never transmitted over the network. Base64 encoding converts text to ASCII-safe format for transmission through systems that only support text, commonly used in email and HTTP. ROT13 is a simple letter substitution cipher that replaces each letter with the letter 13 positions after it in the alphabet, providing basic obfuscation. Caesar cipher shifts each letter by a fixed number of positions, one of the simplest and most widely known encryption techniques. Whether you're a security professional protecting sensitive data, a developer implementing encryption in applications, a student learning about cryptography, a privacy-conscious user securing personal information, or anyone needing to encode or decode text for various purposes, this tool provides instant encryption and decryption with multiple algorithm options. Perfect for understanding different encryption methods, comparing security levels of various algorithms, and learning about modern cryptography. Use it to secure passwords, encrypt notes, encode URLs, protect API keys, or simply explore the fascinating world of cryptography and data security.

Unlike many online tools that require account creation or have hidden costs, Text Encryptor is completely free and requires no signup. Simply open the tool and start using it immediately. Your privacy is our priority - all processing happens locally in your browser, and your data is never stored on our servers.

Whether you're a professional, student, or casual user, Text Encryptor is designed to be intuitive and efficient. Our tool works seamlessly on desktop computers, tablets, and mobile devices, ensuring you can get your tasks done wherever you are.
