How to decrypt md5 in pl/sql

Hello !
Can somebody tell that how to decrypt password of md5 type encryption.
Is there any way of decrypt md5 .
Regards

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 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.

Can I create ASP user validated website using existing MD5 passwords from SQL table?

I'm attempting to build a user authenticated site in Dreamweaver CS5 using an existing USERS table from another site. The password field in the existing SQL table appears to be MD5 encoded. How can I MD5 encode the form field (or the SQL query) so that it verifies MD5 to MD5?
Currently, it's comparing the form's plain text field to the MD5 encrypted password field in SQL.
I've built a simple login form using the following:
<form id="form1" name="form1" method="POST" action="<%=MM_LoginAction%>">
    <input name="username" type="text" id="username" accesskey="u" tabindex="1" /><input name="password" type="password" id="password" accesskey="p" tabindex="2" /><input name="submit" type="submit" value="submit" />
    </form>
With the stock Dreamweaver Log In User Server Behavior as follows:
<%
' *** Validate request to log in to this site.
MM_LoginAction = Request.ServerVariables("URL")
If Request.QueryString <> "" Then MM_LoginAction = MM_LoginAction + "?" + Server.HTMLEncode(Request.QueryString)
MM_valUsername = CStr(Request.Form("username"))
If MM_valUsername <> "" Then
Dim MM_fldUserAuthorization
Dim MM_redirectLoginSuccess
Dim MM_redirectLoginFailed
Dim MM_loginSQL
Dim MM_rsUser
Dim MM_rsUser_cmd
MM_fldUserAuthorization = ""
MM_redirectLoginSuccess = "results.asp"
MM_redirectLoginFailed = "error.html"
MM_loginSQL = "SELECT user_name, password"
If MM_fldUserAuthorization <> "" Then MM_loginSQL = MM_loginSQL & "," & MM_fldUserAuthorization
MM_loginSQL = MM_loginSQL & " FROM dbo.users WHERE user_name = ? AND password = ?"
Set MM_rsUser_cmd = Server.CreateObject ("ADODB.Command")
MM_rsUser_cmd.ActiveConnection = MM_ADSX_STRING
MM_rsUser_cmd.CommandText = MM_loginSQL
MM_rsUser_cmd.Parameters.Append MM_rsUser_cmd.CreateParameter("param1", 200, 1, 32, MM_valUsername) ' adVarChar
MM_rsUser_cmd.Parameters.Append MM_rsUser_cmd.CreateParameter("param2", 200, 1, 32, Request.Form("password")) ' adVarChar
MM_rsUser_cmd.Prepared = true
Set MM_rsUser = MM_rsUser_cmd.Execute
If Not MM_rsUser.EOF Or Not MM_rsUser.BOF Then
    ' username and password match - this is a valid user
    Session("MM_Username") = MM_valUsername
    If (MM_fldUserAuthorization <> "") Then
      Session("MM_UserAuthorization") = CStr(MM_rsUser.Fields.Item(MM_fldUserAuthorization).Value)
    Else
      Session("MM_UserAuthorization") = ""
    End If
    if CStr(Request.QueryString("accessdenied")) <> "" And false Then
      MM_redirectLoginSuccess = Request.QueryString("accessdenied")
    End If
    MM_rsUser.Close
    Response.Redirect(MM_redirectLoginSuccess)
End If
MM_rsUser.Close
Response.Redirect(MM_redirectLoginFailed)
End If
%>
Please help!

unfortunately classic asp does not have a built in function for md5. what we used for our legacy sites is a javascript that hashes a string to MD5. here's the code we've used in the past http://pajhome.org.uk/crypt/md5/md5.html
your asp should have something like this...
<script language="jscript" src="path_to_js_file/md5.js" runat="server"></script>
<%
'hash the password
Dim md5password       ' md5password variable will hold the hashed text from form variable txtPassword
md5password = hex_md5(""&Request("txtPassword")&"")
' based on the code you posted...
MM_rsUser_cmd.Parameters.Append MM_rsUser_cmd.CreateParameter("param2", 200, 1, 32, md5password) ' adVarChar
%>

How can I enable embedded pl/sql gateway to run on port 80

I have a new 11G install on OEL 4.0, database created. I would like to be
able to access the instance using the pl/sql gateway. Works fine with
port 8080, the default. How to I enable it to run on port 80?
I found this statement in the following docuementation:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb22pro.htm#ADXDB2500
Using HTTP(S) on Nonstandard Ports
By default, HTTP listens on a nonstandard, unprotected port: 8080. To use HTTP(S) on
the standard port, such as 80, your DBA must chown the TNS listener to setuid ROOT
rather than setuid ORACLE, and configure the port number in the Oracle XML DB
configuration file /xdbconfig.xml.I have root priviledges on the box.
I've tried setting the listener file permissions:
chown root:dba /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
chmod 6775 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
Also put root in the dba group.
The permissions turn out like this:
-rwsr-sr-x 1 root dba 830854 Jun 17 21:04 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
I stopped the listener, bounced the database, and started the listener again.
But it still shows the process being owned by oracle:
oracle 29682 1 0 21:08 ? 00:00:00 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr LISTENER -inherit
Changing the port is easy:
Connected to:
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SYS>select dbms_xdb.gethttpport as "HTTP-Port" , dbms_xdb.getftpport as "FTP-Port" from dual;
HTTP-Port FTP-Port
8080 2100
At this point, I can access the apex home page with the following url:
http://hostname:8080/apex/f?p=4550:10:1454849288245548
I can than change it to port 80:
SYS>begin
dbms_xdb.sethttpport('80');
dbms_xdb.setftpport('2100');
end;
2 3 4 5
PL/SQL procedure successfully completed.
SYS>SYS>select dbms_xdb.gethttpport as "HTTP-Port" , dbms_xdb.getftpport as "FTP-Port" from dual;
HTTP-Port FTP-Port
80 2100
When I try to access apex with the following url:
http://rmdcopslnx1.us.oracle.com/apex/f?p=4550:10:1454849288245548
I get the following:

* Could the site be temporarily unavailable? Try again later.
* Are you unable to browse other sites? Check the computer's network connection.
* Is your computer or network protected by a firewall or proxy? Incorrect settings
* can interfere with Web browsing.I can set the port. Just can't talk to it.
This is the entry from the listener log:
<msg time='2008-07-03T15:40:09.741-06:00' org_id='oracle' comp_id='tnslsnr'
type='UNKNOWN' level='16' host_id='hostname'

TNS-12560: TNS:protocol adapter error
TNS-00516: Permission denied

</msg>
So this looks like an permissions problem. But where? I posted
this on the apex forum here:
Re: How can I enable embedded pl/sql gateway to run on port 80
They suggested asking here.

No, that thread did not provide the information that I need. Some more data:

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"..

Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to docs.oracle.com.
Locate the link for your Oracle product and version, and click on it.
You are now at the entire documentation set for your selected Oracle product and version.
BOOKMARK THAT LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab (for 10.x) or the "Master Book List" link (for 11.x) you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- *Read a chapter a day from the Concepts Manual*.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- *When you have finished reading the Concepts Manual, do it again*.
Give a man a fish and he eats for a day. Teach a man to fish and he eats for a lifetime.
