Military-Grade Message & Image Encryption
Military-Grade Message & Image Encryption
GhostCrypt is a highly secure, client-side encryption utility designed to protect your sensitive text messages and images. By leveraging the AES-256-GCM (Advanced Encryption Standard with Galois/Counter Mode) algorithm, it ensures military-grade confidentiality and data integrity.
When you enter a secret password, the application derives a strong cryptographic key using PBKDF2 (with 100,000 iterations). The encryption process happens entirely within your browser. This means your raw data and your secret password never leave your device. Only the final, scrambled payload is generated, which you can safely share across any public channel like WhatsApp, Email, or Discord.
Note: For IT and security compliance, the encrypted payloads (the scrambled text) are logged for audit purposes. However, your passwords are strictly kept on your device and are never transmitted.
Yes! You can upload an image (we recommend keeping it under 2MB). The image is converted into binary data and encrypted exactly like text. When decrypted with the correct password, the image will display perfectly.
Encryption adds random data (like a salt and initialization vector) to secure your message. If you encrypt an image, the resulting text can easily exceed 50,000 characters. For large payloads, simply use the Download as .txt File option instead of copying and pasting.
No. We do not have your secret password. Without the exact password used to encrypt the data, it is mathematically impossible to decrypt the payload. We maintain zero-knowledge of your actual content.
Yes, GhostCrypt is 100% free to use for personal and commercial purposes. We support the site through minimal, unintrusive advertisements.
