Cipher

Now you have heard in Movies and other sources about the use of so called "Cipher Encryption". This code actually exists from the Caesar times. He did not trust his messengers with information by encoding his text into Cipher. Then it evolved into other more complex and more artificial encryptions. If a program uses cipher code to encode information that would use 448bit encryption. You will have a choice of selecting 4 different types of cipher styles above this text via the "http://www.trincoll.edu". (All credits to this information goes to "www.trincoll.edu"

The Caesar Cipher

One of the simplest examples of a substitution cipher is the Caesar cipher, which is said to have been used by Julius Caesar to communicate with his army. Caesar is considered to be one of the first persons to have ever employed encryption for the sake of securing messages.

Simple Substitution Cipher

A cipher is a method for encrypting a message — i.e., for transforming the message into one that can’t be easily read. The original message is called the plaintext or clear and the encrypted message is called a cryptogram or ciphertext. A substitution cipheris one in which each letter of the plaintext is replaced by some other symbol.

The Vigenere Cipher — A Polyalphabetic Cipher

One of the main problems with simple substitution ciphers is that they are so vulnerable to frequency analysis. Given a sufficiently large ciphertext, it can easily be broken by mapping the frequency of its letters to the know frequencies of, say, English text.

The Gronsfeld Cipher — A Variant of Vigenere

This page describes a method for attacking a Gronsfeld cipher. It is based on the approach described in F. Pratt, Secret and Urgent, NY: Bobbs-Merrill, 1939.

PLACE BAG OVER THE CREDIT CARD AND SWIPE AGAIN

If you’ve ever stood at a checkout line and frantically swiped your credit (debit) card again and again, only to see error messages, try this little trick:

Slip your bashful card inside a plastic shopping bag (typically hanging right next to the card swipe reader). Smooth out all wrinkles and ensure that the bag is tight and taut on the magnetic stripe side of the card. Now swipe your card/bag combo through the card reader. Success! The plastic bag adds just enough thickness to your card for a persnickety card reader to accept.
