Cryptograms are essentially secret codes. They were first used for secret wartime communications. One of the oldest versions recorded was a strip of paper wra

According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product

pped around a stick. This type of cryptogram was used by the Spartan Army over two thousand years ago.

The paper was wrapped around the stick or staff, edge-t

Example Of A Cryptogram

A Caesar Cipher is a simple "shift cipher." You simply substitute

As you can imagine, any cryptogram as simple as this can be easily broken. Since there are only 26 "shifts" possible

This is why simple substitution ciphers, while used for entertaining puzzles, are not used by them

.

As there is an increasing trend of the combination products companies manufacturing such products should be able to tackle the problems involved in the de
