MD5 hash value from a file
Hello Oracle Community,
version 11.1
well a lof of questions from me today. Is it possible to generate a MD5 value from a file with PL/SQL and if so how can I do it ?
Ilja
Hi Ilja,
I never work with files from Oracle, but maybe you could try combining these:
UTL_FILE.GET_RAW (
fid IN utl_file.file_type,
r OUT NOCOPY RAW,
len IN PLS_INTEGER DEFAULT NULL);
DBMS_OBFUSCATION_TOOLKIT.MD5(
input IN RAW)
RETURN raw_checksum;Regards
Peter

I am trying to load any 9.0.3 firmware on my UCM 5.0.4.2000-1 server. Every newer firmware I load throws the following error. I have verified the MD5 is correct and also downloaded the file several times with the same result. I can load the same firmware file on another UCM server and it loads fine. Any ideas?
Thanks in advance!
Error Message:
The selected signed file could not be authenticated. The file might have been tampered with or an error might have occured during download. Please verify the MD5 hash value against the Cisco Systems web site: 9b:b6:31:09:18:15:e7:c0:97:9f:e6:fe:9a:19:94:99

UCM version: 5.0.4.2000-1Thanks for your reply. We have a lab environment where I maintain UCM 5.0, 5.1, 6.0, 6.1, 7.0, 7.1 and 8.0 servers each running the latest released firmware for our QA testing team. I have downloaded and installed the latest device packages but find that if I try to install any firmware newer then 8.3.1 on either 5.0.4 or 6.0 i start getting MD5 hash authentication errors. It looks like 9.0.3 firmware should work on UCM 5.0 and 6.0 so I am lost as to why I can't seem to update any firmware for any model phone if it is newer then version 8.3.1 on either 5.0 or 6.0. while 5.1 and 6.1 work without issues. Maybe it is just a bug. I mostly wanted to see if anyone else has experienced this or if it is just me.

Generating MD5 hash value for any specific flat file
Hi experts,
I am developing a program that will generate flat files and also I should generate the MD5 Hash value for each and every flat files. My question is how can I generate the MD5 hash value for the generated .txt files.
Thanks in advance
ShabirYou can use functions
MD5_CALCULATE_HASH_FOR_CHAR for text file
MD5_CALCULATE_HASH_FOR_RAW for binary -
DBMS_CRYPTO MD5 hash value does not match 3rd party MD5 free tool
Hello,
I am using Oracle Version: 11.2.4.
I have a problem where the MD5 value from DBMS_CRYPTO does not match the hash value from 3rd party MD5 free tool (MD5 Checksum Calculator 0.0.5.58 or WinMD5Free v1.20) and also the MD5 hash value calculated by an ingestion tool where I am transferring files to. The MD5 hash value that the ingestion tool calculates is the same as the 3rd party MD5 free tools I have. This occurs only on some of the XML files that I generate using XSQL(xmlserialize, xmlagg, xmlelement, etc.) and DBMS_XSLPROCESSOR on a Linux OS. The XML files are transferred from the Unix OS to my Windows 7 OS via filezilla.
I found a thread on this forum that also had a similar issue so I copy/paste the java functions. They are listed below(both are the same expect for the character set):

Moderator action : added [code ] tags to format properly. In future please add them yourself.>
I have a problem where the MD5 value from DBMS_CRYPTO does not match the hash value from 3rd party MD5 free tool (MD5 Checksum Calculator 0.0.5.58 or WinMD5Free v1.20) and also the MD5 hash value calculated by an ingestion tool where I am transferring files to. The MD5 hash value that the ingestion tool calculates is the same as the 3rd party MD5 free tools I have.
I found a thread on this forum that also had a similar issue so I copy/paste the java functions.
>
And in that thread (Re: MD5 HASH computed from DBMS_CRYPTO does not match .NET MD5 I provided the reason why DBMS_CRYPTO may not match hashes produced by other methodologies.
I have no idea why you copied and posted all of that Java code the other poster and I provided since code has NOTHING to do with the problem you say you are having. Thte other poster's question was how to write Java code that would produce the same result as DBMS_CRYPTO.
You said your problem was understanding why DBMS_CRYPTO 'does not match the hash value from 3rd party MD5 free tool ...'. and I answered that in the other forum.
>
The Crypto package always converts everything to AL32UTF8 before hashing so if the .NET character set is different the hash will likely be different.
See DBMS_CRYPTO in the PL/SQL Packages and Types doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_crypto.htm
If you look at the spec header for the DBMS_CRYPTO package it shows this note:
-- Prior to encryption, hashing or keyed hashing, CLOB datatype is
-- converted to AL32UTF8. This allows cryptographic data to be
-- transferred and understood between databases with different
-- character sets, across character set changes and between
-- separate processes (for example, Java programs).
-- If your 3rd party MD5 free tool (MD5 Checksum Calculator 0.0.5.58 or WinMD5Free v1.20) do not use the AL32UTF8 character set then the hashes will likely be different. You can't modify DBMS_CRYPTO so if the hashes need to match you need to use 3rd party tools that either use the correct character set or can be configured to use the correct character set.
The problem in the other thread was how to WRITE Java code that uses the correct character set and I showed that OP how to do that.
So unless you are writing your own Java code all of that code you copied and pasted is useless for your use case. -

How to retrieve value from xml file
hi all,
can somebody pls tell me how to retrieve value from xml file using SAXParser.
I want to retrieve value of only one tag and have to perform some validation with that value.
it's urgent .
pls help me out
thnx in adv.
rituhi shanu,
the pbm is solved, now i m able to access XXX no. in action class & i m able to validate it. The only thing which i want to know is it ok to declare static ArrayList as i have done in this code. i mean will it affect the performance or functionality of the system.
pls have a look at the following code snippet.
public class XMLValidator {
static ArrayList strXXX = new ArrayList();
public void validate(){
factory.setValidating(true);
parser = factory.newSAXParser();
//all factory code is here only
parser.parse(xmlURI, new XMLErrorHandler());
public void setXXX(String pstrXXX){
strUpn.add(pstrXXX);
public ArrayList getXXX(){
return strXXX;
class XMLErrorHandler extends DefaultHandler {
String tagName = "";
String tagValue = "";
String applicationRefNo = "";
String XXXValue ="";
String XXXNo = "";
XMLValidator objXmlValidator = new XMLValidator();
public void startElement(String uri, String name, String qName, Attributes atts) {
tagName = qName;
public void characters(char ch[], int start, int length) {
if ("Reference".equals(tagName)) {
tagValue = new String(ch, start, length).trim();
if (tagValue.length() > 0) {
RefNo = new String(ch, start, length);
if ("XXX".equals(tagName)) {
XXXValue = new String(ch, start, length).trim();
if (XXXValue.length() > 0) {
XXXNo = new String(ch, start, length);
public void endElement(String uri, String localName, String qName) throws SAXException {
if(qName.equalsIgnoreCase("XXX")) {
objXmlValidator.setXXX(XXXNo);
thnx & Regards,

Passing Value from one File to Another !!!
Hi Friends,
I have an issue, I have two different Swing programs (two seperate java files). I want to transfer value from one file to the another. Like we do in Servlets or JSP, we use sessions or Hiddenfields. The same way I want to retriev value in a new file from a previous one.
Hope that all u champs out there have the answer to my query.
Thanks,
[email protected]This is a B2B comms question...
A quick and dirty method is to use Socket/ServerSocket and use a basic protocol to do the transfer, if you are feeling heroic then use XML as the message format...
A lot depends on whether your applications are running on separate boxes, i.e. do you need to communicate across a network...
If not, if they are always going to be on the same "box" then you could just use well-known places for files...not portable but effective... -
Passing The Value from csv file to a WebApplication
Hi to all,
i have a csv file. my requirement is to transfer data from csv file to a specified website(i have no control over website.). How can i solve this problem?
I am giving you an Example for better understanding:
I have a csv file named "abc.csv" in which my login id and password of my mail is written.
abc.csv:----
Userid:Admin
Password:Admin
Now i want a program which will take these values and pass these values to my mail server so that i can login without entering manualy.
How can i solve this Problem
Thankshi
what You are telling is correct when we our form is in the same application. but i said that i have only csv file and my program to read that file and now with those values from csv fil ei have to lo in a diffrent site over which i don,t have any control. means i can not know the name of action class of that login page. -
Reading Design values from readback file
Hi All,
I am trying to understand the process of reading back design signal values from readback file.
I have both the .ll file and the readback.bin file
To get the readback file, I executed the below command:
% readback_hw_device [current_hw_device] -readback_file <filename.rbd> -bin_file <filename.bin>
Now, I want to know the command or process to read the design signal values from this .bin file? Is there any command provided by Xilinx or anything else that I can do to read the signal values?
Rgds
Sapan
Hi Syed,
Thanks for the reply. It was actually my own started thread. I had few questions unanswered from that post:
Question:
The procedure for readback that I am following here is based on the ug908-vivado programming and debugging.
I first uploaded the image on FPGA and then I executed the following commands in Vivado Hardware Manager
% create_hw_bitstream -hw_device [current_hw_device] -mask fpga.msk fpga.bit
% verify_hw_devices [current_hw_device] #### For readback verify
readback_hw_device [current_hw_device] -readback_file <filename.rbd> -bin_file <filename.bin> #####for readback capture
This looks a little different from the one suggested in your document. Can you please confirm if my steps are correct?
Using the above procedure, I did not have to explicitly send readback commands to the FPGA using JTAG as mentioned in doc:
http://www.xilinx.com/support/documentation/sw_manuals/xilinx2015_1/ug908-vivado-programming-debugging.pdf
However the other doc http://www.xilinx.com/support/documentation/application_notes/xapp1230-configuration-readback-capture.pdf mentions sending commands to the device in order to be able to do a readback.
So I am a little confused which one is correct?
Also which document will give the words per frame information for FPGA XC7VX485TFFG1761?

MD5 implementation gives different hash values from java1.2 to java 1.3
Hi,
I have MD5 implementation using Java api. When i run the program using Java 1.2, I get one version of hash value. When i run the same program using Java 1.3/1.4 I get a different version of hash value.
the hash value generated by java1.2 authecticates correctly with server but the one generated by 1.3/1.4 gives me authetication failure with the server.
I serious doubt some encoding issue with md5 implementation from java 1.2 to java 1.3/1.4. I would like to know what is the root cause for getting a different hash with java 1.3/1.4
Thanks

Sample Applescript: scraping values from numbers files into a master file
Hi, I have programming experience in c and other languages, but am new to applescript and so am learning a lot from this forum.
My goal is to make a timesheet system for my Dad (for a bday present) where every time he helps a client, he fills out a newly created numbers file - and after a week or so, he can run a script that scrapes certain values from each numbers file and places it into a master numbers file. Then saving and closing the file.
Vince, it sounds like you've written a script that does this feature of looping through all numbers files in a folder and putting select values from each numbers file into a master numbers file (after clearing the previous values of the master file).
Specifically, I'm looking for a sample script that opens up a numbers file, clears its table, then fills this table by scraping one value from a particular cell in every numbers file in a folder.
If anyone has a similar script they would be willing to post or email to me, for me to use as a foundation and to learn from, I would be very very very grateful. My email is forman.jq at gmail dot com.I guess that this script may be a good starting point.

Help with getting array values from a file
Hey ppl. Im doing a programming assignment just now and im completely stumped. I know i can ask my tutor but that will take a week (he is never in) so i was wondering if any of you could help. The basic idea is that you have to store numbers read from a file into an array. The catch is that you are not given the size of the array, you have to discover this by counting the numbers in the file. It terminates when -1 is discovered. This 'count' then states the size of the array.
I got this done ok and i thought I was on easy street after that. All i had to do was read the numbers into the array but alas its not working. The compiler gives it the ok, but when i run the program i get the following error
Exception in thread "main" java.lang.nullPointerException
at marks.main(marks.java:48)
By the way line 48 is as follows
numbers[index] = Integer.parseInt(infile.readLine().trim());
and here is the evil program!!!!!
//Paul Rodger ***MARKS*** 14/1/02
//A program which takes numbers from a file and enters them into an array.
//The stream of numbers is terminated when the number -1 is discovered
import java.io.*;
class marks
static BufferedReader keyboard = new
BufferedReader(new InputStreamReader(System.in));
static PrintWriter screen = new PrintWriter(System.out, true);
static public void main(String[] args) throws IOException{
FileReader file = new FileReader("numbers.txt");
BufferedReader infile = new BufferedReader(file);
//local Data
int COUNT;
double x;
char ans;
COUNT=0; // initialising the counter
//inputs values and calculates the sum
x = Double.parseDouble(infile.readLine().trim());
while (x>=0){
COUNT++;
x= Double.parseDouble(infile.readLine().trim());
// display the count
screen.println("the number of values entered was : " +COUNT );
// stores numbers in the array
int[] numbers = new int[COUNT];
for(int index=0 ; index < COUNT; index++)
numbers[index] = Integer.parseInt(infile.readLine().trim());
infile.close();
Any help is appreciated!What was suggested is this -
prior to this line ...
int[] numbers = new int[COUNT];insert these lines ...
file = new FileReader("numbers.txt");
infile = new BufferedReader(file);An alternative solution, one which reads the file only once, is to do it this way ...
1. read the numbers and put them into a List (either ArrayList or Vector)
2. instantiate the array based on the size of List (list.size())
3. populate the array from the list -
Reading values from properties file
Hi All,
I am in need of a help from you all.I have a login.jsp which gets username and password as user input and checks in the servlet that if it was admin and admin it will take to index.jsp and if it was other than admin and other users it should take to index1.jsp.For now i am using an if condition to check the values and to dispatch the request.I need to use a properties file for this and need to check by getting the values from the properties file.And also it should check for each entry in properties file and if it finds any matches it should take to the corresponding page.
Please help me in achieving this.
Thanks,
