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
