How Ghost Cipher Works
1
Your message is AES-GCM encrypted into raw bytes using your passphrase
2
Those bytes are converted to a bit sequence (0s and 1s)
3
AI writes a story where each word choice encodes one bit — "walked" vs "moved", "old" vs "ancient"
4
The output looks like completely normal text — no cipher visible anywhere
5
Decryption uses the same passphrase to extract the bit choices and reconstruct the original message
/ How Decryption Works

Standard AES mode: enter the passphrase shared by the sender. Ghost Cipher fetches the encrypted message from the server and decrypts it in your browser using AES-GCM. The plaintext never travels over the network — only the ciphertext is stored, and only for 24 hours.

Ghost Cipher Pro mode: paste the full AI-generated text you received (including the [ref:...] marker at the end) and enter the passphrase. The decoder reads the word choices across the text, reconstructs the bit sequence, and decrypts it back to the original message.

Standard AES
Enter only the passphrase. The ciphertext is fetched from the server automatically. Works for messages encrypted in Standard mode.
Ghost Cipher Pro
Paste the full Ghost Cipher text including the [ref:...] tag. Enter the passphrase. The message is extracted from the word choices in the text.
