java - How to increase the mcrypt-generic-init key size from 8 to 16? -

-

When I run encryption, I get an error: Warning: mcrypt_generic_init () [function.mcrypt-generic - init]: The size of the key is too large; Supply Length: 16, Max: 8

My code: 

  $ size = mcrypt_get_block_size ('des', 'ecb'); $ Input = pkcs5_pad ($ input, $ size); $ Key = '* 5hS7e6 $ 23 n # 2m7s'; $ Td = mcrypt_module_open ('des', '', 'ecb', ''); $ iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($ td), MCRYPT_RAND); Mcrypt_generic_init ($ td, $ key, $ iv); $ Data = mcrypt_generic ($ td, $ input); Mcrypt_generic_deinit ($ TD); mcrypt_module_close ($ TD); $ Data = base 64_ode ($ data); $ Return data;   
 I'm trying to write an encryption & amp; Decryption between Java (code provided by Java developer) & amp; PHP. But Java only supports 16 characters.  
 Thank you.   
 
 
 You can not DEE encryption key length supports 56bit (7 characters), block size 64 Bit (8 characters). More characters are useless, I do not know how long the operation Java is, but it gets smaller in some way.  
 I would ask if the Java program uses DES or Triple-DES encryption. Triple-DES uses 168 bit key length so that you can use the keys with 16 characters.  
 Some side notes- DES is considered unsafe, so I hope Triple-DES is used.

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] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
