security - Can One-Time-Pad key be reused if encrypted plaintext is random? -

-

I want to encrypt random data with a single key, which is shorter than plain text.

Do I use AES or any other strong encryption algorithm, or can I use OTP, i.e. block by blocking the travel text (black block) with only the unique key?

Example data is 1024 bits tall and is random. The key is 128-bit long (even at random). Is it safe to encrypt data by adding 8 consecutive 128-bit blocks with the same key?

For example the data is 1024 bits tall and is random. The key is 128-bit long (even at random). Is it safe to encrypt data by adding 8 consecutive 128-bit blocks with the same key?

If your data is random, then the answer is yes.

You can view your actual data as an OTP key. It is purely random and used only once, so there is no way to recover any keys or data.

Pass DB Connection parameters to a Kettle a.k.a PDI table Input step dynamically from Excel -

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
