In
cryptography, a
Caesar cipher, also known as
Caesar's cipher, the
shift cipher,
Caesar's code or
Caesar shift, is one of the simplest and most widely known
encryption techniques. It is a type of
substitution cipher in which each letter in the
plaintext is replaced by a letter some fixed number of positions down the
alphabet. For example, with a shift of 3,
A would be replaced by
D,
B would become
E, and so on. The method is named after
Julius Caesar, who used it in his private correspondence.
Example
The transformation can be represented by aligning two alphabets; the cipher alphabet is the plain alphabet rotated left or right by some number of positions. For instance, here is a Caesar cipher using a left rotation of three places (the shift parameter, here 3, is used as the key):
Plain: ABCDEFGHIJKLMNOPQRSTUVWXYZ
Cipher: DEFGHIJKLMNOPQRSTUVWXYZABC
When encrypting, a person looks up each letter of the message in the "plain" line and writes down the corresponding letter in the "cipher" line. Deciphering is done in reverse.
Ciphertext: WKH TXLFN EURZQ IRA MXPSV RYHU WKH ODCB GRJ
Plaintext: the quick brown fox jumps over the lazy dog
On Both location
N 51° 52.267 W 008° 26.531
N 51° 52.496 W 008° 26.654
find 2 shift parameter's for alphabet and numbers line.
Than, decrypt the cache location.
