How to decrypt MD5 data

Hi,
I am Having the password of my application in MD5 format.I need to get the decrypted password.How to obtain that.
Thanks In Advance,

I'm making some assumptions based on the limited info you have provided...
You are trying to log into a webapp, the user supplies a username/password so you have both in plaintext.
You are getting the stored password from the webapp's storage and it is coming out in "MD5" format because it was digested when it was stored.
What you need to do is digest (aka hash) the user-supplied password using the MD5 algorithm and compare the result with what was taken from storage. If they match, the password is correct and let the user in, if not, reject the login attempt.
simplified steps:
- user foo registers, uses "password" as password, webapp digests the password using MD5 and gets: 286755fad04869ca523320acce0dc6a4
- user foo tries to login and supplies "cat" as the password, webapp pulls the stored password for foo out (286755fad04869ca523320acce0dc6a4) and then digests what the user just passed in "cat" and gets 54b8617eca0e54c7d3c8e6732c6b687a
does 54b8617eca0e54c7d3c8e6732c6b687a = 286755fad04869ca523320acce0dc6a4? NO, don't let user in.
- user foo tries to login and supplies "password" as the password, webapp pulls the stored password for foo out (286755fad04869ca523320acce0dc6a4) and then digests what the user just passed in "password" and gets 286755fad04869ca523320acce0dc6a4
does 286755fad04869ca523320acce0dc6a4 = 286755fad04869ca523320acce0dc6a4? YES, let user in.

Actually i have a encrypted password field in the table and i want to compare that field with the value in the textbox .
For that purpose i cant compare the simple text value(in the text box)with the encrypted value in table . so i need to first convert the simple text value in md5 and then compare that value with value in table (password field).
So i want to know that how to convert value to MD5 in PL/SQL .

How to decrypt MD5

Hi,
how can I decrypt encrypted text with MD5?

You CAN'T. Message digests (including MD5) is the one way function. You can only calculate MD5 for the candidate text and then compare with the stored MD5.

How to decrypt data when you can't get the private key in Windows?

I'm very confuse. My english is poor, but I try to say my question clearly.
When browser connects to a https website which needs client certificate to authenticate the identity, the browser will send client certificate to web server.
Then the web server will use the certificate to encrypt some data and send it to browser.
Then broswer should have private key to decrypt that.
But as I know, if I install a pfx format personal certificate, I can set can't export private key, which means you can't get the private key to use it. So how can
the browser decrypt the data without private key?
By the way, what is CSP, use CSP's interface can we use CryptoAPI
to decrypt data without private key?

Answer for question is "you cant"..

How to insert encrypted data by using blowfish into mysql database

Hi
I have encrypted data using blowfish algorithm . And i tried to insert that encrypted data into mysql. it was stored but i dont know that it stores in the same encrypted formate
When i am trying to get the encrypted data from the mysql database and decrypting that data i am getting errors.
Exception are like
input length should be multiple of 8 bits
or Given block are not properly padded
and when i am displaying the data using system.out.println ();
the string is not similar to the string which is in database.
what is the problem how can i solve my problem
thank you

It sounds like your column is a VARCHAR so you need to Base64 or Hex encode the cipertext bytes before putting them in the database.

How to decrypt external hard drive so it can be re-partitioned

I can't repartition an external hard drive which has been encrypted as a time machine backup drive. So I am trying to remove the encryption. But I can't figure out how to decrypt the drive either. I know it is still encrypted since it requires the password when I mount the drive. I have successfuly erased all data at the partition level. But there is no ERASE tab at root level. When I try to re-partition it shows a greyed out "current" and the only thing I can do is to create a 2nd partition the identical size as the first.
I have tried ejecting and remounting. I have tried 2 different macs. Repair disk shows "it appears to be ok". Any suggestions?

To do this, follow these steps:
1. Open the OS X Terminal utility and run the following command:
diskutil cs list
The output of this command will look like a hierarchical tree. Locate the long alphanumeric code next to the words "Logical Volume Group" (this code is called a "UUID"), and copy this code to the clipboard by highlighting it and then pressing Command-C.
2. Run the following command to destroy the logical volume group, replacing "UUID" with the alphanumeric string from the first command.
diskutil cs delete UUID
When done this will clear the volume and allow it to be formatted and otherwise customized. See the following screenshot for what this should look like (the two commands are underlined in blue:

SoundTrak Crashed!! How I got my data back.

If you get the beachball during a record, by what could be the screen saver kicking in or the disk drive going to sleep (all of which should be disabled to start with), then you might get a file which shows size and a good time of creation, but it won't play or show a waveform. In fact even Audacity won't touch it. Here's how to recover the data. Hopefully you know your settings you were using, aka 48khz, 44.1 etc. For the sake of this post, I used 24bit 44.1khz AIFF sample rescue information. Bear with me.
First locate your bad file in the soundtrak pro recordings folder. Duplicate it. Note its size. Take the copy and get it to the desktop. Do not muck with the original.
Download the 0xED (thats the name) hex editing app. You can also have a dupe file of a working file from an earlier session. Your going to want to copy it as well and put it on your desktop. You'll need the header info from it.
Open your known good file wih 0xED. Highlight and copy from the beginning of that file address 0000000 thru 0000FF7 with a contrl C on the keyboard.
Open your bad file copy. They can both be opened at the same time. Highlight those same addresses and contrl V that data into your bad file. Pay close attention thats all you changed. Nothing should have shifted anywhere else. If you screwed up, cntrl Z out of that and try it again until it looks like a clean paste. Yes the data is going to be different in your paste operation as thats why your file is hosed to begin with. Hopefully you just now patched your file. SAVE the potential repaired file using the save icon in 0xED. Open our repaired file
with Audacity, or SoundTrak Pro. You should have a workable file now. If not, go back and try again as perhaps you messed something up or didnt save the repair properly. Its crucial you use data from a good file of the same settings to fix the bad one. If your not sure of the settings you used, try a couple possibilities. Most people use the same settings with only a few variations so your choices should be few hopefully. NOTE: To test your file, close out all instances of the bad file in Sountrak Pro or your new file won't chck out if it is indeed fixed. DO a fresh load of your new file into a freshly started Sountrak Pro or Audacity.
What else have I used? I used SoundHack a few times. Its a bit strange and clunky. The results are hard to nail down. I ended up with a file that played like MickeyMouse but I was able to use Audacity to cut the speed down by 50% and save the audio.
The problems I encountered to get me to this point were as described in the beginning of this write up. I had the beachball. One time Sountrak just quit without warning. Again, the data was there but just wasnt closed out properly.
I hope this saves someone from a disaster. It saved me. I never gave up.
cheers
Johnny
P.S. Here's the data for an AIFF 44.1k 24 bit good file if it can be of use. You'd want to place it right over your bad file in 0xED. No guarantees. Make sure your muckng with a copy and NOT your original file...... (yes thats 4C twice, thats not a misprint)

How can I Move data from one column to another in my access table?

I have two columns, one that stores current month’s data and one that stores last month’s data. Every month data from column 2 (this month’s data) needs to be moved to column 1 that holds last month’s data. I then null out column 2 so I can accumulates this month’s data.
I understand how to drop a column or add a column, how do I transfer data from one column to another.
Here is my trial code:
<cfquery name="qQueryChangeColumnName" datasource="#dsn#">
ALTER TABLE leaderboard
UPDATE leaderboard SET points2 = points3
</cfquery>
Unfortunately, I get the following error:
Error Executing Database Query.
[Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] Syntax error in ALTER TABLE statement.
How can I transfer my data with the alter table method?

I looked up the Access SQL reference (which is probably a
good place to start when having issues with Access SQL), and
it suggests you probably need a WHERE clause in there.
I agree the documentation is a good place to start. But you should not need a WHERE clause here.
Too few parameters. Expected 1.
If you run the SQL directly in Access, what are the results? At the very least, it should provide a more informative error message..

How do i transfer data from one internal tabe to another.

Hi All,
         How do i transfer data from one internal tabe to another.
         Can i do it ebven if he tables are different in structure.
Please Advice.
Thanks in advance.

Hi Saket Tiwari,
I hope the earlier post by kashyap is good enough an answer. anywas in addition to it let me give a detailed
explanation of how you can populate an internal table.
1) Append data line by line.
     Syntax : APPEND [<wa> TO / INITIAL LINE TO] <itab>.
this appends new line to internal table <itab>.
2) Using COLLECT statement.
             COLLECT is another form of statement used for populating the internal tables. Generally COLLECT is used while inserting lines into an internal table with unique standard key. The syntax for COLLECT statement is as shown
     Syntax : COLLECT [<wa> INTO] <itab>.
3) Using INSERT statement
     Syntax INSERT [<wa> INTO / INITIAL LINE INTO] <itab> [index <idx>].
INSERT statement adds a line/work area to the internal table. You can specify the position at which the new line is to be added by using the INDEX clause with the INSERT statement.
Now coming to your request..
To append part or all of an internal table
     Syntax
              APPEND LINES OF <itab1> [FROM <n1>] [TO <n2>] TO <itab2>.
*     Note:
Without the FROM and TO options, this statement appends the entire table <itab1> to <itab2>.*
b) To insert part or all of an internal table into another internal table
     Syntax
          INSERT LINES OF <itab1> [FROM <n1>] [TO <n2>]
          INTO <itab2> [INDEX <idx>].
c) Using Move statement.
To copy entire contents of one table into another in one execution
     Syntax MOVE <itab1> To <itab2>.
               OR
          <itab1> = <itab2>.
but u hav to be careful because he contents of itab2 will eb overwritten on the execution of this statement.
These copy the contents of ITAB1 to ITAB2. Incase of internal tables with header line we have to use [] inorder to distinguish from work area. So, to copy contents of internal tables with header line the syntax becomes,
ITAB1[] = ITAB2[].
Coming to the letter part of your question, Yes, we can copy values between tables having different structures.
for this we use
                            MOVE-CORRESPONDING <itab1> TO <itab2>
    this executes the statement for their header lines. Searches for the sub-fields which occur both in itab1 and itab2 and then generates, for all relevant field pairs which correspond to the
        sub-fields ni , statements of the form MOVE itab1-ni TO itab2-ni. The other fields remain unchanged.
I hope the information provided has been of your help.
Reward if useful.

Jose

this code is ..get all data(changed and not changed)
but i want get changed data only, not all data.
how to get changed data?
Edited by: Ki-Joon Seo on Dec 27, 2007 6:04 AM

Hi,
To get only the changed data in the ALV grid of a WD, you need to capture the "ON_DATA_CHECK" of the ALV grid.
To this please do the following in the ALV initialization of the ALV table settings :
    lr_table_settings->set_data_check(
            IF_SALV_WD_C_TABLE_SETTINGS=>DATA_CHECK_ON_CELL_EVENT ).
You may also do this:
    lr_table_settings->set_data_check(            IF_SALV_WD_C_TABLE_SETTINGS=>DATA_CHECK_ON_CHECK_EVENT)
The above two ways would depend on when do you need to check for the changed data. If you want to check the data as soon as it is entered, then use the first method. Else, use the second method.
You need to register an EVENT HANDLER for this event.(You may do this in your VIEW or Component Controller).
In this Event handler, you would find an importing parameter R_PARAM which is a ref type of      IF_SALV_WD_TABLE_DATA_CHECK.
The attribute T_MODIFIED_CELLS of this interface IF_SALV_WD_TABLE_DATA_CHECK will contain the modified cells of the ALV with the old & new values.

How to pass the data from a input table to RFC data service?

Hi,
I am doing a prototype with VC, I'm wondering how VC pass the data from a table view to a backend data service? For example, I have one RFC in the backend system with a tabel type importing parameter, now I want to pass all the data from an input table view to the RFC, I guess it's possible but I don't know how to do it.
I try to create some events between the input table and data service, but seems there is no a system event can export the whole table to the backend data service.
Thanks for your answer.

Thanks for your answer, I tried the solution 2, I create "Submit" button, and ser the mapping scope to be "All data rows", it only works when I select at least one row, otherwise the data would not be passed.
Another question is I have serveral imported table parameter, for each table I have one "submit" event, I want these tables to be submitted at the same time, but if I click the submit button in one table toolbar, I can only submit the table data which has a submit button clicked, for other tables, the data is not passed, how can I achieve it?
Thanks.
