Text Encryptor & Decryptor | Password-Based Text Lock
Encrypt text with a secret key or decrypt previously encrypted text for private notes, demos, and local experiments.
Encrypt or Decrypt Text with a Secret Key
Enter text and a password-style secret to create encrypted output, or paste encrypted text with the same secret to restore the original message.
Use Strong, Private Secrets
Short or reused passwords weaken encrypted text. Keep the secret separate from the encrypted output, and avoid pasting highly sensitive personal, financial, or production data.
When This Tool Is Appropriate
Use it for learning, temporary private notes, or browser-based experiments. For business secrets, regulated data, or long-term storage, use a reviewed security workflow.
About This Tool
Text Encryptor encrypts and decrypts plain text using a password-based encryption scheme. It is used to protect sensitive notes, share confidential messages securely, or store private information in an encrypted format.
When to Use It
Use this when you need to send a sensitive message over an insecure channel, when storing a confidential note in a shared document, or when demonstrating basic encryption concepts.
How to Use
- Enter the text you want to encrypt.
- Enter a strong password.
- Click Encrypt to produce the encrypted output.
- Share the encrypted text and the password through separate channels.
- Use Decrypt mode with the same password to recover the original text.
Frequently Asked Questions
How strong is the encryption?
The tool uses AES-256 encryption, which is the industry standard for symmetric encryption and is considered secure for protecting sensitive information.
Can I recover the text if I forget the password?
No. Without the correct password the encrypted text cannot be decrypted. There is no password recovery mechanism.
Should I send the password with the encrypted message?
No. Send the encrypted text through one channel (email, chat) and the password through a separate channel (phone call, separate message) to prevent interception.
