Text Encryptor & Decryptor

Text encryption converts readable plaintext into encoded ciphertext. You achieve confidentiality by applying symmetric algorithms like AES or TripleDES. The algorithm combines your text and a secret password to create an unreadable string. Decryption reverses the process. Together, encryption and decryption protect messages from unauthorized access during storage or transmission.

This tool lets you encrypt or decrypt text instantly without local installation. It uses well-known algorithms from the CryptoJS library executed entirely in your browser. You choose an algorithm, enter a password, and switch modes. The application generates ciphertext for secure sharing or restores plaintext for immediate reading. No data leaves your device.

Use the encryptor to protect personal notes, credentials, or code snippets before emailing or archiving them. Collaborative teams secure configuration secrets without backend services. Educators demonstrate cryptography concepts interactively. Developers confirm algorithm behavior during troubleshooting. Because processing is client-side, the tool works offline once loaded, safeguarding privacy even on restrictive corporate networks.

Technical Details:

Review key features and a concise encryption example below.

• Supports AES, DES, TripleDES, RC4, Rabbit, Rabbit Legacy, and RC4Drop algorithms.
• Performs cryptographic operations entirely in your browser for maximum privacy.
• Derives 256-bit keys by hashing your password with SHA-256.
• Uses ECB mode with Base64 output for straightforward copying.
• Vue reactivity updates ciphertext or plaintext immediately after any change.
• Copy button employs Clipboard API and a fallback to ensure compatibility.
• CryptoJS loads from CDN and remains cached for offline use.

Step-by-Step Guide:

Follow these steps to secure or reveal text.

1. Paste plaintext or ciphertext in the top textarea. Tip
2. Pick an algorithm from the Encryption Algorithm dropdown.
3. Supply a strong password in the Password field. Caution
4. Select Encrypt or Decrypt using the mode toggle. Processing happens instantly.
5. Review the result in the lower textarea.
6. Press Copy to clipboard to reuse the output elsewhere.
7. Bookmark the page to retain query parameters for repeat operations.

FAQ:

Find quick answers to common questions.

Troubleshooting:

Resolve issues quickly with these pointers.

• CriticalEmpty output: Ensure you entered a non-empty password.
• “Invalid input” alert: Check that ciphertext is valid Base64.
• Wrong plaintext: Confirm the correct algorithm and password pair.
• Clipboard fails: Grant clipboard permissions or use the manual copy fallback.
• Cyrillic appears garbled: Verify UTF-8 integrity before encryption.

Advanced Tips:

Enhance your workflow with expert advice.

• Create passphrases of 12+ random words for stronger keys.
• Append a version tag inside the ciphertext comment field for future reference.
• Use browser DevTools to inspect CryptoJS output blocks during debugging.
• Enable browser caching to run the tool offline in secure environments.
• Automate repetitive encryptions by pre-populating query parameters in the URL.
