Generating fixed length DSA signatures

hello,
i have this query. I am working on an application that generates a DSA signature on a string that is of 8bytes. i am using SHA1withDSA algorithm. My data string is always 8 bytes. However the signature length is always varying ,sometimes the signature that is generated is of 46 characters sometimes 47 and sometimes 48. Is it possible to control this and generate a fixed length Digital Signature????
Thanks in advance

Could yo resolve the problem? I've got the very same problem and y don't know what to do.

Generate fixed-length unique strings

Hi all,
I'm trying to generate 16 byte unique string from two input strings. Essentially, the unique string will be used as primary key in the database. The two input strings are (siteUrl, productId) in which siteUrl is the url of a website which has one or more productId. Each productId in a site is unique but there might be duplicate productIds from different sites. I want to generate 16 byte ids from each pair of (siteUrl, productId) such that they are unique (or have a very small chance of collision). Has anyone done this before? Please share your experience! Thanks heap!

>>>>>
KajThanks for the answer. However, what I want toknow
is how to convert say productId to unique 8
byte
string. Any idea?What does the product id look like?Product id is usually a string of digits andletters:
2323, 234lasfd1kj3,....
What I'm looking for is a hash function h suchthat:
h(siteUrl) -> 8 byte string
h(productId) -> 8 byte string
I now can combine h(siteUrl) and h(productId) toget
16 byte unique string.
Sorry but you can't! Since the hashes will not be
unique the combination will not be unique.There should be such hash function somewhere but I haven't found it. The definition is here http://www.x5.net/faqs/crypto/q94.html.

On E series Card with 2 counters I want to generate a fixed length pulse train and want to continuously monitor it.

On E series Card with 2 counters I want to generate a fixed length pulse train and want to continuously monitor it.

Depending on the software you are using, there are many shipping examples and example programs on the web that illustrate generating a finite pulse train. The E series boards have the DAQ-STC counter/timer chip, and so make sure you search for DAQ-STC examples. I have included links to a LabVIEW example and Measurment Studio Example in Visual Basic.

Loading "fixed length" text files in UTF8 with SQL*Loader

Hi!
We have a lot of files, we load with SQL*Loader into our database. All Datafiles have fixed length columns, so we use POSITION(pos1, pos2) in the ctl-file. Till now the files were in WE8ISO8859P1 and everything was fine.
Now the source-system generating the files changes to unicode and the files are in UTF8!
The SQL-Loader docu says "The start and end arguments to the POSITION parameter are interpreted in bytes, even if character-length semantics are in use in a datafile....."
As I see this now, there is no way to say "column A starts at "CHARACTER Position pos1" and ends at "Character Position pos2".
I tested with
load data
CHARACTERSET AL32UTF8
LENGTH SEMANTICS CHARACTER
replace ...
in the .ctl file, but when the first character with more than one byte encoding (for example ü ) is in the file, all positions of that record are mixed up.
Is there a way to load these files in UTF8 without changing the file-definition to a column-seperator?
Thanks for any hints - charly

I have not tested this but you should be able to achieve what you want by using LENGTH SEMANTICS CHARACTER and by specifying field lengths (e.g. CHAR(5)) instead of only their positions. You could still use the POSITION(*+n) syntax to skip any separator columns that contain only spaces or tabs.
If the above does not work, an alternative would be to convert all UTF8 files to UTF16 before loading so that they become fixed-width.

Issue with Mapping Spaces for Receiver Flat File Fixed Length

Hi Mapping experts,
my scenario is receiver FILE (fixed length)
so if a validation applied on a target field returns false then I need to pass the spaces having the number of characters defined for that field
example
targetField length = 8
using "IF" function to perform validation,   if validation is true THEN = FIELD
if validation is false ELSE = "________"    (underscore to represent 8 spaces)
the problem is the validation is of multiple occurences in one queue and if the "true" statement is on the 6th row, I get _________ which is the value of the 1st row (which is correct because rows 1 to 5 are all false therefore having the value of ELSE which is _______ mapped to it)
How can I get the value of the TRUE row regardless of what row it is located?
e.g. IF = input is 5 rows of validation,     TRUE is in the 3rd row,   i will get the 3rd row value
       IF = input is 5 rows of validation,     NO TRUE Value,   return 8 spaces
right now when i Display Queue values are
iF:in0          iF:in1          iF:in2          iF:out
1111          false          [_________]     [_________]
2222          false                    [_________]
3333          true                    3333
4444          false                    [_________]
5555          false                    [_________]
In above Queue i only get the value of the 1st row which is ________   --> because my target field occurrences definition in Data Type is 0....1
if I change Data Type occurrences to 1...unbounded I get 5 target fields generated --> WRONG because target file is fixed field, so only one occurence of that target field is required

Can you give me the idea of what validation are you using so that anyone can help you with the UDF straightaway
because you need to have a UDf in place which will iterate the number of times the field occurs and then it will check the entire queue first ,where validation is true and only at the instant it will return the value
if the entire queue is value it will return the 8 underscores
I hope this is what you wanted

Reading a fixed length file

Hi All,
I am trying to read a fixed length file with .DAT extension through an FTP Adapter. I am using a read(polling) operation.
In the file there are three records(H,D,T). The length of all the three records is more than 100.When I am trying to build a schema for that file using native format builder, maximum position that i get is 100 and if i manually try to put the position beyond 100 say 120,while building the schema and then run the composite using the generated schema, the file is not polled from the location So if anyone could help me to clarify my doubts regarding reading of fixed length files.
a. Can i read i fixed length file which contains records whose position is more than 100.
b. If yes, then how do i do that?
Any help is appreciated.
Thanks in Advance.

Here's one way to start. Extend this class for the particular functionality you want:import java.io.DataInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
/** Processes binary files which have embedded data records. */
public abstract class BinaryInputFile extends File
* Class constructor.
* @param fileName The input file name.
* @throws NullPointerException if the <code>pathname</code> parameter is <code>null</code>
protected BinaryInputFile(String fileName) throws NullPointerException
   super(fileName);
* Reads the file, one line at a time, passing each line to the subclass� process()
* function.
* @throws IOException if an error occurs.
public void process() throws IOException
   DataInputStream stream = new DataInputStream(new FileInputStream(this));
   process(stream);
* Process the file data.
* @param stream The input stream.
protected abstract void process(DataInputStream stream);

Fixed length file to xml file

Hi,
Fixed length file to xml files.
i have to generate 2 xml files based on a field in the incoming file. structures of both xml files are same.
I want to know how many target data type ,target msg interfaces have to be created?
Thanks.

Ok got you. Best thing would be to use a simple OS command copy in your receiver communication channel. So do one mapping and generate one file and then use the OS command in receiver comm. channel after message processing then it should work for you.

Fixed Length records using SQL

hi , using the following code in a file that generates an output file with a fixed length 300 character lines.
SPOOL C:\PHONE_SAMPLE.OUT;
SET HEADING OFF;
SET PAGES 0;
SET ECHO OFF;
SELECT rpad(CONTACT_ID,15),rpad(PHONE1,15),rpad(PHONE2,15),rpad(PHONE3,15),rpad(PHONE4,15),rpad(PHONE5,15),rpad(PHONE6,15)
,rpad(CALLSEQ,6),rpad(NDCALLSEQ,6),rpad(LANG,3),rpad(FIRST,25),rpad(LAST,25),rpad(CONCODE,10),rpad(EMAIL,30),rpad(TXTMSG,20),rpad(WVEND,20),
rpad(APPTSTART,14),rpad(APPTEND,14),rpad(APPTTYPE,10),rpad(APPTLOCTION,10),rpad(FILLER,1)||'\n'
FROM PHONE_SAMPLE;
SPOOL OFF;
After I run this I get my data and the following below - my end of Character line, and then "22 rows selected" - How do I remove the 22 rows selected. and stop at \n. Any help appreciated.
Is it a set command I am missing ?
\n
22 rows selected.

Hi,
SET FEEDBACK OFF
And you don't need SET HEADING OFF when you have SET PAGES 0
And you don't need to end SET commands with ';' since they are SQL*Plus commands

How to map xml to a fixed length string?

Hi All,
I have a requirement to map request xml to a string of fixed length and format:
For eg,

</Person>
Target:
String of format
Name : 8 chars
Age : 2chars.
so the required mapping should result in
"George 21".
Note: 2 blanks after "George" to allow for 8 characters. Is this kind of mapping possible using ALSB xquery? I have tried to create a MFL representation for the string , and used it in the xquery as the targer but it is generating
"George21".Only data present in source is getting mapped :(

My advice would be to use MFL transformation for that.
Documentation about MFL can be found at edocs: http://edocs.bea.com/alsb/docs26/fbhelp/index.html

Fixed Length RFC Values?

I have an RFC call I need to make. The results of the call contained a fixed length field. Naturally, the leading/trailing whitespace of this field is trimmed by the XML parser. To persist the whitespace I'll need to use CDATA which is unparsed. However, I haven't found a way to modify the data structure or call to make that XML element use the CDATA block. Can anyone share their tips for solving this condition?

Hi,
CDATA conversion shd be done in the function Module. unfortunatley i am not ABAPer so i don't how, but i know this shd be done at ECC.
when the function module is coded to generate the field with CDATA, PI will not trim the spaces.
This is not the solution but thought this info may guide you in right path

Problem with using DSA signatures ON CARD

Hi ppl,
I've encountered a rather really wierd problem using DSA signatures on a java card applet.
I just create the key using these two lines and i get a response which is not supposed to happen...
KeyPair dsakey = new KeyPair (KeyPair.ALG_DSA, KeyBuilder.LENGTH_DSA_1024 );
dsakey.genKeyPair();
when i jus execute this portion(there shudn be a response coz i've written 4 one) but this is the unexpected trace on the shell
cm> /send 00150000
=> 00 15 00 00 ....
(259128 usec)
<= 7C 16 C8 12 D0 7A EF EE A1 52 6D 00
nevermind the 6D 00 response it jus means that the INS value is not recommended
The wierd part is i haven written any code for handling response here which jus means that somethin is happenin when the key is initialized... n secondly i don know what this 10 byte value represents also and it keeps changing each time i execute...
Please throw some light if anyone knows anythin or solved some issue like this before...
card specs... jcop 21 36k version 2.3.1 however this issue persists on simulator as well...
Thx in advance
cheers

Yeh lex
Figured it out ... Thx anyways ... Using RSA signatures... ^_^

Need to download a file which si space delimted and has fixed length char

Hi,
I have a custom report which downloads an output file in text format.I need the contents to be space delimited.My file data contains numbers as well as characters.I ahve pased the parameter WRITE_FIELD_SEPARATOR = ' ' in the FM.Hwoever the space is introduced only oif the column value is a character.If its a number/digit,the columns are not seperated by space.
Now my data appears like that:
0000101310179.28 +0827200808 DHLBSRF VISA AUG 2008US021SW111 RYAN,BICOVNY
I want my data to be like this :
0000101310 179.28 + 0827200808 DHLBSRF VISA AUG 2008 US02 1SW111 RYAN,BICOVNY
DO I need to pass any additinal parametre?Also for fixed length characrets,do i need to pack/unpack data before passing to the FM ?
Thanks.

Import data from a Fixed Length File into Oracle database

Hi,
I would like to import data from a Fixed Length text file into a table using HTML DB application.
As of now, i have a .sql file(that uses external table) to import the data into Oracle tables
I would like to integrate this in my HTML DB application so that the user can directly import the data into the table.
Sample data
XXXYYYYZZZZZ
Data should be read to table that has
Col1 Col2 Col3
XXX YYYY ZZZZZ

Hi,
I would like to import data from a Fixed Length text
file into a table using HTML DB application.AFAIK, fixed length imports are not something you can do directly with the HTML DB tools or available APIs.
As of now, i have a .sql file(that uses external
table) to import the data into Oracle tables
I would like to integrate this in my HTML DB
application so that the user can directly import the
data into the table.Any fixed-length data needs to have a specification associated with it that indicates which character position begins a new column and what each column represents. Some also include what datatype should be used for each of those.
If you really want to do this I would suggest that you create a table that you can store the file spec in. It would probably have columns for field name, start position, length or end position, datatype and any alias/column name you might want to apply. You would then use this table in a PL/SQL procedure (probably a package with the main processing procedure and various supporting procedures/functions) to read the file into memory, apply the file spec to each line and then do inserts into your table.
Obviously, this is just a concept or strategy. Implementing it will depend on your PL/SQL skills and determination. If you want to pursue this strategy I'm sure you can find some jump-starts by doing a search on the PL/SQL forum.
This may not sound like an answer - but the answer is you need to code it to fit your requirements. Hope that helps.

Parameters for Ingesting wide fixed-length files?

I created an SSIS process to ingest fixed-length text files into this table.
CREATE TABLE [dbo].[Temp_Source_Fixed](
[Column 0] [text] NULL,
[ID] [int] IDENTITY(1,1) NOT NULL,
CONSTRAINT [Temp_Source_Fixed_ID] PRIMARY KEY CLUSTERED
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
It works fine with most of the files, but one file has almost 26000 characters per row and the process halts with a truncation error.
I suspect that if I change a parameter on the connection manager it will work, since I can manually use
the SSMS wizard to import manually if I specify Text Stream (DT_Text) for the data type of Column 0 versus String (DT_STR).
For the connection manager I have
In the connection string I have Provider=SQLNCLI10.1 and Auto Translate=False.
In Misc parameters, DelayValidation=False.
For the Data Flow Task I have
DefaultBufferSize is 10485760
Any ideas on what I need to change?
Thanks,
Jnana

You need the column in question defined in SSIS as DT_Text.
You need to either drop the flat file connector and re-do it with this datatype, or access the Advanced Editor input and output column and alter its datatype there
