Question about Encryption...
Post 302423904 by iam_ako on Sunday 23rd of May 2010 07:06:56 AM
05-23-2010
well i want to encrypt the file by adding the ods together..
then decrypt the file by subtract their ods again..
i mean..
file1 contain : My name
code file contain: secret
now what i want to do.. is to convert file1 to it's hex.
then convert the code file to it's hex also
suppouse file1 will be:
0001 1000 100 101 01
and code file will be:
1111 111 111 11 110
then i want to sum the two outputs.. and whatever the sum is equal convert it to characters
0001 100 100 101 01 +
1111 111 111 11 110
----------------------------------
1112 211 211 211 120 ----> this will be the encrypted
then convert 1112 211 211 211 120 to it's equal in characters
it's kind of complex and maybe either me cant understand myself..
thank you again.... and waiting ur help guys

deckanji(5) File Formats Manual deckanji(5) NAME
deckanji - A character encoding system (codeset) for Japanese DESCRIPTION
The DEC Kanji codeset consists of the following characters: ASCII or JIS X0201 Roman letters Katakana characters specified by JIS X0201 JIS X0208 characters User-defined characters (UDC) DEC Kanji uses a combination of single-byte data and two-byte data to represent these characters. JIS X0201 is a single-byte character set and consists of Roman letters and Katakana characters, which are Japanese phonetic symbols. The Roman letters defined in the JIS X0201-1976 standard are the same as ASCII letters. (For information on the ASCII character set, refer to ascii(5).) However, JIS X0201 replaces the ASCII tilde (~) character with a horizontal bar (located at the upper part of a character cell), and replaces the backslash () with the Japanese currency sign (Yen). The JIS XO208 standard specifies two-byte character values that represent a variety of characters, including ideographic symbols. DEC Kanji Encoding All ASCII characters are represented by single-byte 7-bit values in DEC Kanji. That is, the most significant bit (MSB) is always set off in the byte that represents an ASCII character. The Roman letters and the Katakana characters specified by JIS X0201 are also single-byte val- ues in which the most significant bit (MSB) is set off and on, respectively. The code table for JIS X0208 characters is divided into 94 rows, numbered from 1 to 94. Each row has 94 columns, also numbered from 1 to 94. JIS X0208 defines a total of 6877 characters which include: Special symbols, in rows 1 and 2 Numerals and Roman letters, in row 3 Hira- gana characters, in row 4 Katakana characters, in row 5 Greek letters, in row 6 Russian letters, in row 7 Symbols for drawing graphs, dia- grams, and lines, in row 8 First level Kanji characters, in rows 16 to 47 Second level Kanji characters, in rows 48 to 84 To comply with the JIS X0208 standard, each JIS X0208 character is a two-byte value in the DEC Kanji codeset. The MSB of both the first and second bytes is always set on to distinguish JIS X0208 characters from ASCII/JIS Roman or user-defined characters. For each JIS X0208 character, The first byte of the two-byte value determines the row number and the second determines the column number in the JIS X0208 code table. The following formula shows the code value for a JIS X0208 character in relation to its row and column numbers: 1st byte = A0 + Row number 2nd byte = A0 + Column number For example, if a character is positioned at the first column of the 36th row, its code value is C4A1, which is calculated as follows: 1st byte = A0 (hex) + 36 = C4 (hex) 2nd byte = A0 (hex) + 01 = A1 (hex) For user-defined character (UDC) definitions, DEC Kanji provides an area of 2914 positions (from row 1 to row 31). Each UDC is represented by a two-byte value, just like a JIS X0208 character value. However, the MSB of the second byte of a UDC is set off to distinguish it from a JIS X0208 character. The code range of the UDC area is A121 to BF7E. The following formula calculates the code of a UDC in relation to its row and column numbers: 1st byte = A0 + Row number 2nd byte = 20 + Column number For example, if a UDC is positioned at the first column of the 16th row, its code value is B021, which is calculated as follows: 1st byte = A0 (hex) + 16 = B0 (hex) 2nd byte = 20 (hex) + 01 = 21 (hex) Codeset Conversion The following codeset converter pairs are available for converting Japanese characters between deckanji and other encoding formats. Refer to iconv_intro(5) for an introduction to codeset conversion. For more information about the other codeset for which deckanji is the input or output, see the reference page specified in the list item. eucJP_deckanji, deckanji_eucJP Converting from and to Japanese Extended UNIX Code: eucJP(5). iso-2022-jp_deckanji, deckanji_iso-2022-jp Converting from and to the ISO 2022-JP codeset: iso2022jp(5). iso-2022-jpext_deckanji, deckanji_iso-2022-jpext Converting from and to the ISO 2022-JPexp codeset: iso2022jp(5). JIS7_deckanji, deckanji_JIS7 Converting from and to the JIS7 codeset: jiskanji(5). sdeckanji_deckanji, deckanji_sdeckanji Converting from and to the Super DEC Kanji codeset: sdeckanji(5). SJIS_deckanji, deckanji_SJIS Converting from and to the Shift JIS codeset: shiftjis(5). Note that Shift JIS encoding is equivalent to the Microsoft code-page format used on PCs for Japanese. Therefore, you can use these converters to convert data between DEC Kanji and PC code-page format. For information on PC code pages, see code_page(5) UCS-2_deck- anji, deckanji_UCS-2 Converting from and to UCS-2 format: Unicode(5).
