Can I get fixed length output after encryption using PBEwithMD5andDES?

Hi,
I am currently using "PBEWITHMD5ANDDES" algorithm to encrypt the string and later it is encoded using BASE64. I need to store the value in Database so I need output to be of fixed size. Currently output depends on the input string length. My input string can vary in length.
I cannot use Message digest for storing it database as I need to decode too.

You can't possibly have a fixed encrypted output size regardless of the input size and be able to recover the original. Just think about it for a bit. This would enable infinite compression.
PBEWITHMD5ANDDES uses PKCS5 padding and so produces an output which is (n+8)/8 blocks of 8 bytes so 1,2,3 ... 7 become 8 bytes, 8,9,10 ... 15 become 16 bytes etc etc etc.

Facebook is not loading properly and all my text and images are lined up along the right side of the page. How can this get fixed to the way it use to be?

Everyone who logs into Facebook on my Firefox has this problem however if we use Internet Explorer - facebook looks normal.

If you have increased the minimum font size then try the default setting "none" as a high value can cause issues like you described.

How can I get the length of a sequence using script

I am trying to get the length of an image sequence that was imported using importOptions.sequence. I need to check that the length is a correct number, and if it is too short/long it gives an error message.
Is there a way to do this?
Thanks

//Assumes that your clip is the first item in your project
var a = app.project.item(1).duration;     //Returns clip length in seconds
var b = app.project.item(1).frameDuration     //Returns a single frame length in seconds
var c = a/b;     //If you divide the clip duration by the frameDuration, you should get clip length in frames

I can not get itunes to open after I have downloaded it and closed it and tried to get bck into it

I can't get imovie to open after trying to shift the image to my TV by clicking fn F3. If I hold the mouse on the imovie icon for a few seconds the imovie window opens but if I click anywhere on the window it disappears

I can't get imovie to open after trying to shift the image from my macbook pro to the tv screen like I have done many times before. If I double click on the imovie icon, imovie doesn't open, but the strip across the top shows iMovie, file, edit , clip, view, text share window help tabs across the top. The iMovie window will appear if I click on the iMovie icon on the dock for a few seconds, or if I do control F3 at the same time, but when I click on the window it disappears. When I hover the mouse over the iMovie window that appears the window has a blue border around it. when I move the mouse outside the iMovie window the blue border goes away. If I sweep 4 fingers from the top of the screen down, the screen dims a little but the iMovie window doesn't appear. If I click play under the view tab I can hear audio, but still no iMovie window. It's as if the window is being blocked by the desk top somehow.

I have an hp office jet 4500 and os maverick 10.9.4 and I can't get it to print after last upgrade, multiple malfunctions and error, help?

I have an hp office jet 4500 and os maverick 10.9.4 and I can’t get it to print after last upgrade, multiple malfunctions and error, help? I have tried deleting and resetting printer and re-installing update 6 times. Last update attempt showed none available??? I can’t load the software directly from HP because their only option is to use the software update option on the mac....frustrated!!! Help!!
I get blank pages that just run through the printer and a stats window that just 33% complete and goes no further.

I am going on the guess that an old driver is still installed...
Use Finder Go > go to folder, and go to /Library/Printers and delete the HP folder(s).
Reset the Printing System:
OS X Mavericks: Reset the printing system
Now, Add the printer in Print & Scan prefs.

Can you get your photos back after the iphone does a restore

Can you get your photos back after the iphone does a restore?

Actually, wrong.
The tech support people can help with Playbook purchased apps. If you've called and they said they cannot, you were lied to.
Even in the link you posted, in #10, it states clearly "App Refund related matters are handled by BlackBerry Customer Care." That, my friend is accessed by the support number. Again, if you were told otherwise, you should inform them of such or ask for a manage/supervisor.
And, you don't have a "Partner ID" because you are not a "Partner". The section you're referring to applies to mobile providers, which are the Partners.
Good luck.

How can you get a calendar back after deleting it

You will have to restore the device from a backup on icloud. (this assumes you have backups turned on in settings>icloud)
http://support.apple.com/kb/HT1766?viewlocale=en_US&locale=en_US
Go to Settings>General>Reset and tap Erase All Content and Settings. This will erase your device. Then you will go through the setup screens again as you did when your device was new, and when given the option, select Restore from iCloud Backup.

I don't know if this is a similar problem but I wrote 2 notes yesterday on my iphone. I opened my mail to print them and they appeared as notes but wouldn't load. Then I looked at them on my iphone and I could see the notes but they quickly updated to blank with a time of the last edit the same time I tried opening them on my computer.
Yesterday I updated to 4.3.4 I don't know if somehow that affected them. Are they stored somewhere else. Can I get them back?

You can restore the phone and when prompted to restore choose from icloud account. BUT MAKE SURE there is 1.) an icloud backup for your phone. 2.) you are using the same apple id.

Hi Clembo60,
Welcome to the Apple Support Communities!
I understand that your text messages are missing after an update on your iPhone. If you have a backup of your device on either iTunes or iCloud, you can restore from that backup and bring your information back. Please review the attached article, which covers how to back up and restore from backups, for more information.

Can someone tell me the implications of using the command RESET DATABASE on my system days after I did the open reset logs? I opened the database with the ALTER DATABASE OPEN RESETLOGS in SQL not RMAN and I see the below note.....
Re: Can't get dataguard to recover after SAN crash.
To reset the incarnation of the target database in the RMAN repository, which means to do either of the following actions:
•Inform RMAN that the SQL statement ALTER DATABASE OPEN RESETLOGS has been executed and that a new incarnation of the target database has been created. Note that if you run the RMAN command ALTER DATABASE OPEN RESETLOGS (not the SQL statement with the same keywords), then RMAN resets the target database automatically so that you do not have to run RESET DATABASE. By resetting the database, RMAN considers the new incarnation as the current incarnation of the database.

Hey High Socks,
Thanks for the question. If I understand correctly, iTunes isn't working when you try to launch it. I would recommend that you read this article, it may be able to help you isolate or resolve the issue.
