Answers to Questions (FAQ)
What is the ASCII standard? (Definition)
The ASCII character coding standard describes a correspondence tabular array for coding characters (letters, numbers, symbols) on a calculator. This standard was defined in 1975 and contains 128 vii-flake codes including 95 printable characters.
Today this standard is old and has been superseded by Unicode, which is backward compatible with ASCII.
How to encrypt using ASCII tabular array cipher
Encryption consists of replacing each character with its value in the ASCII tabular array (run into below).
Example: Convert dCode cord in ASCII, that is writing 1100100 1000011 1101111 1100100 1100101 in binary (7-bit) or 100 67 111 100 101 in decimal.
Characters which don't exist in the encoding table cannot be coded (no special characters, accents, etc.)
How to decrypt ASCII tabular array cipher
ASCII conversion consists of replacing each value (binary, octal, decimal or hexadecimal) with the corresponding graphic symbol in the ASCII table. Its representation tin can be formatted into binary (0-1), octal (0-7), decimal (0-nine) or hexadecimal (0-9a-f).
Example:
| ASCII Values (Format) | Texte clair |
|---|---|
| 65 77 69 82 73 67 65 78 (Decimal) | AMERICAN |
| 83 116 97 110 100 97 114 100 (Decimal) | Standard |
| 1000011 1001111 1000100 1000101 (Binary 7bit) | CODE |
| 49 4E 46 4F 52 4D 41 54 49 4F 4E (Hexadecimal) | Information |
| 111 116 124 105 122 103 110 101 116 107 105 (Octal) | INTERCHANGE |
How to recognize an ASCII ciphertext?
The bulletin is generally written either in binary, or in decimal, or in hexadecimal (or rarely in octal).
The most frequent values must correspond to messages characters lowercase or capital (between 65 and 122 in decimal)
Any reference to skiing (ASCII ≈ a ski) is a inkling.
On how many characters is represented an ASCII code?
The ASCII lawmaking is almost ever represented on one byte (8bits) fifty-fifty if it occupies just 7bits.
In binary, use either 7 bits or 8 $.25 (past calculation a leading null) to represent an ASCII character.
In octal, it is represented with three characters (from 000 to 177).
In decimal, the number is between 1 and 128 (from 1 to 3 characters).
In hexadecimal, 2 characters are used (from 00 to 7f).
How practice I alter from a lowercase ASCII alphabetic character to an capital letter letter?
In the ASCII lawmaking there is a departure of 32 between an uppercase letter and a lowercase letter. So add 32 to the ASCII code of a capital letter letter of the alphabet to get a lowercase and decrease 32 from the ASCII code of a lowercase letter to take a capital letter letter. The respective binary operation consists in setting the 5th fleck (starting from the right) to 0 (upper instance) or 1 (lower case).
Example: A=0100001 (65) and a=0110001 (65+32=97)

How to lawmaking non-ASCII characters such as accents?
Utilise another coding tabular array, such as Unicode or in Europe the norm ISO/CEI 8859-1 Latin which includes the ASCII tabular array in its offset office (from 0 to 127) so specific characters for the following numbers (128-255).
