Assuming you already have the two file locally (you will need to fetch FileA from the web server using something like wget).
Also that the SHA keys are a string of 64 hex digits (0-9 a-f) which are separated from other text in file by one or more white space characters.
You could collect the keys using grep like this:
Grep can then output any key(s) in KeylistA not in KeyListB like this.

I am writing a script that ssh's out to our various servers and extracts diskspace info to generate into a report. With the mix of servers linux/solairs 8-10/AIX the easiest way is to use df -k (though I much rather prefer df -h).
I have pasted the relevant code:

Hi,
Is it possible to convert MD5 passwords to SHA-512?
I'm about to migrate an old slackware server to Debian, then I noticed that they don't use same encryption method.
I'm aware that I can change the encryption method in Debian to MD5, but as far as I understand SHA-512 is more secure,... (2 Replies)

array_diff_key
ARRAY_DIFF_KEY(3) 1 ARRAY_DIFF_KEY(3)array_diff_key - Computes the difference of arrays using keys for comparisonSYNOPSIS
array array_diff_key (array $array1, array $array2, [array $...])
DESCRIPTION
Compares the keys from $array1 against the keys from $array2 and returns the difference. This function is like array_diff(3) except the
comparison is done on the keys instead of the values.
PARAMETERS
o $array1
- The array to compare from
o $array2
- An array to compare against
o $...
- More arrays to compare against
RETURN VALUES
Returns an array containing all the entries from $array1 whose keys are not present in any of the other arrays.
EXAMPLES
Example #1
array_diff_key(3) example
The two keys from the key => value pairs are considered equal only if (string) $key1 === (string) $key2 . In other words a strict
type check is executed so the string representation must be the same.
<?php
$array1 = array('blue' => 1, 'red' => 2, 'green' => 3, 'purple' => 4);
$array2 = array('green' => 5, 'blue' => 6, 'yellow' => 7, 'cyan' => 8);
var_dump(array_diff_key($array1, $array2));
?>
The above example will output:
array(2) {
["red"]=>
int(2)
["purple"]=>
int(4)
}
NOTES
Note
This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using
array_diff_key($array1[0], $array2[0]);.
