+# False Bottom: A deniable encryption scheme
+False Bottom is a [deniable encryption](https://en.wikipedia.org/wiki/Deniable_encryption) scheme.  
+As such, unlike traditional encryption algorithms, False Bottom allows for the encryption and decryption of multiple messages to and from a single ciphertext.  
+Each message gets a corresponding key which can only be used to decrypt it.
