# Simple Encryption Methods

## This is a short article on the simplest encryption methods.

In all of these examples I will encrypt "HellBound Hackers"

Binary: Binary consists of 1's and 0's put together in groups of eight. A sample is shown below so you will be able to recognize binary.

Sample: 01001000 01100101 01101100 01101100 01000010 01101111 01110101 01101110 01100100 0100000 01001000 01100001

01100011 01101011 01100101 01110010 01110011

Hex: Hex consists of numbers 0-9 and letters A-F put together in pairs.

Sample: 48 65 6C 6C 42 6F 75 6E 64 20 48 61 63 6B 65 72 73

Caesar Shift: A Caesar shift is when you take a letter of the alphabet and shift it by x places, let's use three as an example, if I used three 'A' would equal 'D', 'B' would equal 'E' and so on. The sample below is shifted by five.

Sample: MjqqGtzsi Mfhpjwx

ROT-13: ROT-13 is a Caesar shift shifted by thirteen letters. ROT-13 stands for ROTated-13.

Sample: UryyObhaq Unpxref

Reverse Text: Reverse text is simple when you take a message and flip it backwards. There are two variants that I'm aware of such

Examples are shown below;

Sample (Variant One): Srekcah Dnuoblleh

Sample (Variant Two): Dnoublleh Srekcah

Octal: The octal system is based on the base-8 number system and consists of the numbers 0-7. Octal numerals can be made from binary numerals by grouping consecutive digits into groups of three starting from the right. For example, the binary representation for decimal 74 is 1001010, which groups into 1 001 010. (Source 'Wikipedia'). I had to read up on octal so please tell me of any mistakes here.

Sample: 110 145 154 154 102 157 165 156 144 40 110 141 143 153 145 162 163

Base 64: (This is a copy from Wikipedia, since I do not know enough about base 64 to explain in my own words.) Base 64 is a positional numeral system using a base of 64. It is the largest power of two bases that can be represented using only printable ASCII characters.

Sample: SGVsbEJvdW5kIEhhY2tlcnM=

This is just a basic introduction to encryption, there are many more methods of encryption and a lot of them are far more advanced

and harder to crack than these.

Note: For the encryptions noted, I was unaware of the background of that encryption, my source for the info listed under 'Octal and

Base 64' was found at 'http://en.wikipedia.org/'

Edit: After mozzer's comment I decided to add in reverse text, octal, and base 64.

01100011 01101011 01100101 01110010 01110011

z3r0phr34kon May 19 2006 - 02:06:43 I voted |

pyrodude0303on May 19 2006 - 03:46:49 nice |

mozzeron May 19 2006 - 16:56:15 Well, there are other really common ones. Reverse text? Octal? Base64? |

HopelessRomanticon May 19 2006 - 20:08:06 Thanks mozzer, I'll try and update it to include those. |

system_meltdownon May 20 2006 - 12:10:37 What about reverse-shifting? That's putting the text backwards and then rotating it if you didn't know |

spywareon May 20 2006 - 12:21:02 What about keyboard-shifting? This: Hellbound Hackers Becomes this: Gwkkviybs Glxjwea (Every letter shifts one place to the left on your jwtviles, I mean, keyboard ) (Voted) |

HopelessRomanticon May 20 2006 - 16:21:08 I'll try to work those in too, thanks for the suggestions. |

xizkon May 21 2006 - 05:11:18 What would your press for "a" in the keyboard shift? |

HopelessRomanticon May 21 2006 - 05:28:43 xizk, I'm assuming "l", I guess you just move across the keyboard. |

minermonkon April 10 2007 - 02:09:27 not nessiserialy (log word but u get it) on a standard uk / us keyboard 'a' shifts to 's' which shifts to 'd'. think about the country before making any updates |

HopelessRomanticon April 25 2007 - 17:27:44 That also depends on which way you're shifting the keys. I assumed he was referring to shifting to the left because 'a' shifted to the left would be the 'caps lock' key on my keyboard so you would move over to the 'l' key. |

dex_poeton January 05 2008 - 13:17:09 also there is a very common cypher called "rail cypher." Say you have the plain text "this is cool." You get rid of the spacing, and divide the message into equal halves. then you have one letter from the first half, one from the second, and so on. The example I gave would look like "TSHCIOSOIL" in cypher text. |
