makekey - generate encryption key
SYNOPSIS
/usr/lib/makekey
DESCRIPTION
makekey improves the usefulness of encryption schemes that depend on a key by increasing the amount of time required to search the key
space. It attempts to read 8 bytes for its key (the first eight input bytes), then it attempts to read 2 bytes for its salt (the last two
input bytes). The output depends on the input in a way intended to be difficult to compute (that is, to require a substantial fraction of a
second).
The first eight input bytes (the input key) can be arbitrary ASCII characters. The last two (the salt) are best chosen from the set of dig-
its, ., /, upper- and lower-case letters. The salt characters are repeated as the first two characters of the output. The remaining 11 out-
put characters are chosen from the same set as the salt and constitute the output key.
The transformation performed is essentially the following: the salt is used to select one of 4,096 cryptographic machines all based on the
National Bureau of Standards DES algorithm, but broken in 4,096 different ways. Using the input key as key, a constant string is fed into
the machine and recirculated a number of times. The 64 bits that come out are distributed into the 66 output key bits in the result.
makekey is intended for programs that perform encryption. Usually, its input and output will be pipes.

makekey can produce different results depending upon whether the input is typed at the terminal or redirected from a file.

makekey - generate encryption key
SYNOPSIS
/usr/sbin/makekey
DESCRIPTION
Makekey improves the usefulness of encryption schemes depending on a key by increasing the amount of time required to search the key space.
It reads 10 bytes from its standard input, and writes 13 bytes on its standard output. The output depends on the input in a way intended
to be difficult to compute (that is, to require a substantial fraction of a second).
The first eight input bytes (the input key) can be arbitrary ASCII characters. The last two (the salt) are best chosen from the set of
digits, upper- and lower-case letters, and `.' and `/'. The salt characters are repeated as the first two characters of the output. The
remaining 11 output characters are chosen from the same set as the salt and constitute the output key.
The transformation performed is essentially the following: the salt is used to select one of 4096 cryptographic machines all based on the
National Bureau of Standards DES algorithm, but modified in 4096 different ways. Using the input key as key, a constant string is fed into
the machine and recirculated a number of times. The 64 bits that come out are distributed into the 66 useful key bits in the result.
Makekey is intended for programs that perform encryption (for instance, ed and crypt(1)). Usually makekey's input and output will be
pipes.

I am learning output the data to a file using "ofstream". I need to read data from a file and output the result to the other file in 2 different ways. To do that I have to provoke two functions, and they have to output the result to the same text file. My problem is: they are correct on the screen... (2 Replies)
Hi,
I have a Variable Char field coming whose value looks like below
562432569856
I need to extract 2 characters from it till the end and put it elsewhere
say
56
24
32
56
98
56
in this case.
Any input is appreciated. (2 Replies)
how can i accept a group of lower case alphabetic input one at a time , ended with 0 and find and display the first letter in alphabetic order. example, input or d f g c should result in c
thanks (1 Reply)
Hello, everyone.
Could someone, please, tell me how to get the number of bytes in the terminal input queue without blocking and without consuming these bytes? I guess it could be called the peek functionality.
I've looked at termio tcgetattr() and tcsetattr() functions but could not find... (4 Replies)
HI,
I require only the file name and the user information from the ls output into a file. The layout of the file is already defined as:
User id is in the first 7 bytes
FName is in the next 50 bytes
Assuming that user id is less than or = 7 bytes and
File name is less than or = 50 bytes... (5 Replies)
1. The problem statement, all variables and given/known data:
Find the first letter in alphabet from the input:
Accept the input of a series of upper case alphabetic letters one at a time. The input ends with a 0. Find and display the first letter in alphabetic order. For example, input... (27 Replies)
