If you closely compare this cipher with that of the York Rite or Blue Lodge, you will see the
subtle differences but know that they are different. By knowing this cipher you will not be able to
decode a 'real' masonic cipher. This example has been presented for "entertainment purposes" and to
educate you about Masonic Ciphers, while keeping within the bounds of our obligations.

The use of symbols is no impediment to cryptanalysis however, and cryptanalysis is identical to that of other simple substitution schemes.

The advantage of steganography over cryptography alone is that messages do not attract attention to themselves, to messengers, or to recipients. An unhidden coded message, no matter how unbreakable it is, will arouse suspicion and may in itself be incriminating and in some countries encryption is illegal.

Steganography vs. Cryptography

*
Steganography’s goal is to keep the presence of a message secret, or hide the fact that communication is taking place
*
Cryptography’s goal is to obscure a message or communication so that it cannot be understood
*
Steganography and Cryptography make great partners. It is common practice to use cryptography with steganography

With these new techniques, a hidden message is indistinguishable from white noise. Even if the message is suspected, there is no proof of its existence. To actually prove there was a message, and not just randomness, the code needs to be cracked or the random number seed guessed. This feature of modern steganography is called "plausible deniability."
