Text Encryptor & Decryptor

Securely encode and decode text using various algorithms.

How to Encrypt & Decrypt Text

  1. Input Text: Type or paste the text you want to process into the "Input Text" box.
  2. Select Algorithm: Choose an algorithm from the dropdown. For strong security, use AES. For simple encoding, use Base64. For a fun, simple cipher, use ROT13.
  3. Enter Secret Key (if required): If you select AES, a "Secret Key" field will appear. Enter a strong password that you can remember. This key is required for both encryption and decryption.
  4. Encrypt or Decrypt: Click the "Encrypt" button to encode your text or the "Decrypt" button to decode it.
  5. Get the Result: The processed text will appear in the "Output Text" box.

About Our Text Encryption Tool

In a digital world, protecting information is crucial. Our Text Encryptor & Decryptor provides a simple, accessible way to apply cryptographic techniques to your text. Whether you need to send a private message, store sensitive notes, or simply learn about ciphers, this tool offers several methods right in your browser. All operations are performed locally on your machine, ensuring your data and secret keys are never transmitted to our servers.

  • AES: The Advanced Encryption Standard is a symmetric encryption algorithm used worldwide. It is highly secure and requires a secret key (password) to encrypt and decrypt data. Remember your key, as there is no way to recover the data without it.
  • Base64: This is an encoding scheme, not an encryption method. It represents binary data in an ASCII string format. It's useful for transmitting data but does not provide security as it can be easily reversed by anyone.
  • ROT13: A simple letter substitution cipher that replaces a letter with the 13th letter after it in the alphabet. It's a fun, classic cipher but offers no real security.

Frequently Asked Questions (FAQ)

Is AES encryption truly secure on this tool?

Yes, the AES algorithm itself is a NIST-approved, industry-standard cryptographic method. Our tool uses a robust JavaScript implementation (CryptoJS) to perform the encryption. The security of your encrypted data depends entirely on the strength and secrecy of your password. Use a long, complex, and unique password for best results. Since all processing is client-side, your key is never exposed to the internet.

What's the difference between encryption and encoding (like Base64)?

Encryption is a two-way process designed for confidentiality. It uses a key to transform data into an unreadable format, and only someone with the correct key can reverse it. Encoding is a two-way process designed for usability. It transforms data into a standard format that can be safely transmitted or stored. It is not secure and can be reversed by anyone without a key.

What if I forget my AES secret key?

If you forget the secret key used for AES encryption, your data is permanently lost. There is no "forgot password" feature or backdoor. The security of the system relies on the fact that only the key can decrypt the data. Store your key in a safe and secure place.
