Look for repeating letter patterns. They may be common letter groups, such as TH, SH, RE, CH, TR, ING, ION, and ENT. Try to decipher two-, three-, and four-letter words. Two-letter words almost always have one vowel and one consonant.

Steganography is the idea to prevent secret information by creating the suspicion. Steganography is less popular than Cryptography. In steganography, structure of data is not usually altered. WebThere have been three well-defined phases in the history of cryptology. The first was the period of manual cryptography, starting with the origins of the subject in antiquity and continuing through World War I. Throughout this phase cryptography was limited by the complexity of what a code clerk could reasonably do aided by simple mnemonic devices. …
