Frequently Asked Questions
How do I encrypt text messages securely?
Enter your text and a strong password. The tool uses AES-256 encryption to convert your message into ciphertext. Only someone with the correct password can decrypt it. Use a password with 12+ characters mixing letters, numbers, and symbols.
What encryption algorithm does text encryption use?
The tool uses AES-256-GCM, the same standard used by governments and banks. AES-256 has never been broken. GCM mode provides both confidentiality (encryption) and integrity (authentication), ensuring the ciphertext hasn't been tampered with.
How do I share encrypted text with someone?
Encrypt the text with a shared password. Send the ciphertext through any channel (email, chat). Share the password through a different channel (phone call, in person). Never send the password and ciphertext through the same channel.
What is the difference between symmetric and asymmetric text encryption?
Symmetric (AES): same password encrypts and decrypts. Fast, simple, but requires sharing the password securely. Asymmetric (RSA): public key encrypts, private key decrypts. No password sharing needed, but slower. The tool uses symmetric encryption.
Can encrypted text be decrypted without the password?
With AES-256, no. Brute-forcing a strong password would take billions of years. However, weak passwords (short, dictionary words) can be cracked. Always use a strong, unique password. The tool warns if your password is too weak.
