How to generate all possible keys for DES algorithm

Hello every one,
I want to generate all the possible key combinations for the DES algorithm 56-bit "actuallly 64 but the last 8 bits are just padding", so can anyone plz help how can i do that? or give me article or something that might help me?
Thanks in advance,
Amr M. Kamel.

I know that but who said that it will be one
processor it will be on distributed and clustered
environment :). I just want to know how to generate
the keys "or write binary".
Thans again for your helpA cluster of 2285 machines will still take a year! The simplest algorithm is to just count from 0 to 2^56 .
If you are thinking of cracking DES then there is a Book I have on my shelf 'Cracking DES' published by the 'Electronic Frontier Foundation' ISBN 1-56592-520-3 . It contains the C code and describes the hardware used. The hardware cost was about $100,000 and it cracks DES in about 3.5 days.
Assuming Moore's law ( http://en.wikipedia.org/wiki/Moore's_law ) applies then it should now take about much less than a day and cost much less than $100,000. BUT - it will take a long time using basic computers.

Generating all possible combinations question

i'm trying to generate all possible combinations for several single column tables each with one string column.
so - if table 1 has values (aa, ab, ac)
table 2 has values (zz, zx)
table 3 has values (qw, qe)
the result set would contain all possible combinations:
aa, ab, ac, zz, zx, qw, qe, aazz, aazx, aaqw, aaqe, aazzqw, aazzqe, aazxqw, aazxqe...etc.
I've tried cross joins - but that does not get the smaller combinations.
I've looked at some code examples but they seem to be focused on single letter or number combinations.
I need to do this using tsql.
code examples or links to such would be of much help.
Thanks.

Something like this might work:
with t1 as (
select val from table1
union all
select ''
), t2 as (
select val from table2
union all
select ''
, t3 as (
Select val from table3
union all
select ''
select t1.val + t2.val + t3.val
from t1 cross join t2 cross join t3

Could anyone generate a SolMan Key for me?

Dear All Experts,
I have to install an ECC 6.0 IDES as soon as possible, but there is something wrong with our solman system, could anyone generate a solman key for me?
my SID is IDS
my host name is sap
and my instance number is 00
It's really urgent, thanks for your kind replies.

Paul, a license key is not the same as the requested SolMan Key.
A License Key is provided by SAP (and will be installed via transaction SLICENSE in case of ABAP Web AS Systems).
A Solution Manager Key is generated through SAP Solution Manager, transaction SMSY. (SAP Note 811923 - Generating the SAP Solution Manager key)
Anyhow, requesting a Solution Manager Key is not appreciated in this forum.

How to generate an XML file for an animation of IK armature

Can someone please tell me how to generate an XML file for an animation of IK armature.
I have a 5 keyframe/16 frame animation of a human character made up of a series of moveiclip symbols that is animated with an IK armature. I need the XML information from the animation.
When I go to Commands > Export Motion XML I get the error message "There is more than one object on frame 1" and then nothing happens.
Thank you,
c

I hope that's not the case. I want to write to adobe about it. I think it's a great feature and it functions really well even though it is not a very developed IK tool. My biggest issue with it is ouput options and integration with motion tweens.
I have seen a lot of examples of animators using it online, just no one talked about output. I just feel it hasn't been developed. It can generate a sprite sheet but only for a single pose frame of the animation, and not all the key frames or pose tweens. I find that functionality quite odd, as if adobe just forgot about IK when added in sprite sheets, etc. and the reason it half works is just an accident.

Any easy way to generate unique primary key for database table?

I'm currently playing with the J2EE reference implementation from Sun which comes with the IBM Cloudscape database. This Cloudscape database supports the use of an AutoIncrement field.
First question: Can I use CMP and assume that the database will generate a proper key for me? Anyone tried it out successfully before?
Also, based on what I've heard so far, it seems that generating database primary key is not really well-supported by J2EE using CMP in that a lot of J2EE developers have to resort to workarounds like using a session bean, JDBC and (1) some seed numbers for ID implanted in the database itself (as in the J2EE tutorial DukesBankApp example) or (2) using the SQL MAX aggregation command + 1. Usign seed number is contradictory to good database design and using MAX is dangerous for heavy traffic application if 2 beans try to insert themselves into the database at the same time (synchronizarion problem).
Anyway I find it dumb that we still have to go back to JDBC and SQL which was the reason why the concept Entity Bean was introduced; to make database persistence transparent! Now it seems that J2EE makes it worse and more troublesome than before.
Second Question: Is there any easy (hopefully transparent/automatic) way of generating primary key ID?

if you want to rely on your container or database then go hard, will probably be faster.
to make a cross container/db soln I used a CMP Entity bean called Sequence with one field for uid
I use one instance and increment the field each time.
To do the logic, I have a utils class with static method, no need for session bean overhead
I reckon this approach is OK considering all things

Impact of generating a new key for Secure Store Application

I inherited my development environment from a predecessor, who did not document the secure store pass phrase anywhere. There are a couple of projects doing development on the system that cannot be impacted, but I need to get Project Server running on the
system, and I cannot get the secure store to accept the credentials I set for the target application. I have recreated the target application several times, but nothing works.
MossHostSsoHost.GetSecureStoreCredentials: Failed to get credentials from Secure Store. SecureStoreProvider threw a SecureStoreException. Exception: Microsoft.Office.SecureStoreService.Server.SecureStoreServiceException: Access is denied to the Secure Store
Service. at Microsoft.Office.SecureStoreService.Server.SecureStoreServiceApplicationProxy.Execute[T](String operationName, Boolean validateCanary, ExecuteDelegate`1 operation) at Microsoft.Office.SecureStoreService.Server.SecureStoreServiceApplicationProxy.GetCredentials(Guid
rawPartitionId, String applicationId) at Microsoft.Office.SecureStoreService.Server.SecureStoreProvider.GetCredentials(String appId) at Microsoft.Office.Excel.Server.MossHost.MossHostSsoHost.GetSecureStoreCredentials(String
secureStoreApplicationId)
So, I am wondering if I need to generate a new key for the secure store application, and what impact that would have on the existing target applications. Can someone please tell me if I generate a new key, will this break the existing applications? Thanks.

Hi Susan,
Once you decide to generate a new encryption key, you could follow the steps in Generate an encryption Key part in the link below:
http://technet.microsoft.com/en-us/library/ee806866(v=office.15).aspx
You should back up the database of the Secure Store Service application before generating a new key. Then refresh the encryption key to propagate the key to all the application servers in the farm.

HT3986 Does anyone know how to enable the "Delete" key for logging on the Windows 7 partition on the latest iMac, via the latest Apple wireless keyboard? Many Thanks

Hi All
Does anyone know how to enable the "Delete" key for logging on the Windows 7 partition on the latest iMac, via the latest Apple wireless keyboard - the standard wired apple keyboard works fine via this key but not the new wireless keyboard?
Many Thanks

Holy crap, this fixes the issue. At least temporarily it has. I should add that my issue was single finger forward/back swipe stopped working on the magic mouse in Firefox since Mavericks came along. I have been fighting this since I upgraded to Mavericks a few months ago. Thank you, tbirdvet. You have no idea how much easier you just made using my iMac again.

How to activate all inactive objects for current user

Hi
How to activate all inactive objects for current user ...
... I have found a (long winded) way to do this:
- Environment / Inactive Objects
- Add to Worklist
- Display Worklist
- Select All
- Activate
this will open a dialog titled "Inactive Objects for <username>"
which has the exact functionality I need ... but I can't figure out how to get to this dialog directly - without so many intermediate steps
the SAP docs repeatedly mention the ability to activate the inactive worklist - but do not mention how
does anybody know the TCode for this dialog?
thanks
ps does the term "mass activation" apply to importing change requests rather than development activation?
Edited by: FireBean500 on Jun 4, 2010 11:07 PM

No other way. But usually it's far more simple as all objects are already in our own worklist.
I wonder why your objects are not already in your worklist, as everytime you create or maintain an object, it is added to your worklist.
