We use the browser's native Web Crypto API. Your password undergoes 100,000 iterations of PBKDF2 hashing to create an AES-256 bit key. This key is then used to securely lock the text.

No. We do not store your data. If you forget the decryption password, the encrypted text is permanently locked and mathematically impossible to recover.

Yes. The output is a secure Base64 string. You can safely send it via SMS, Slack, or email. The recipient must come to this page and enter the secret password to read it.

Absolutely. AES-256 is the gold standard for encryption. It is officially used by banks, the military, and governments worldwide to protect highly classified intelligence.

To ensure security, the algorithm adds a unique "Salt" and "Initialization Vector (IV)" to your message. This prevents hackers from recognizing patterns, increasing the overall length.

Yes! We engineered the Base64 encoder to process data in chunked buffers. You can encrypt massive paragraphs, code blocks, or full documents without crashing your browser.

Yes! Even if you encrypt the exact same word with the exact same password, the output changes completely every time. This is due to the random "Salt" injection, making it extremely secure.

Decryption will fail if you enter the wrong password, or if you did not copy the *entire* block of encrypted gibberish perfectly. Ensure no letters were cut off when copying.

No. This tool operates 100% client-side. You can even load this page, disconnect from the internet, and the encryption will still work perfectly.

Since we package the IV and Salt uniquely into our Base64 string, you must use this specific OTechy tool to decode it cleanly with your password.
