[resolved] String to SHA-256

[Anonymous]

Hello!  
I'm new to java,  I don't konw if talend have a component to  convert a string to SHA-256?  
Or how could we write a code routines in order to use it?  
I have tried download the custom component  tFileDigester  and install in talend, but it can't find in palette. 
Could you help me please? 
Thanks to all

Hi<BR />You need to hard code to convert a string to SHA-256.&nbsp;<BR />Hope the following articles are helpful for you.<BR /><A href="https://community.talend.com/s/article/Create-a-user-routine-and-call-it-in-a-Job-0hHmU" target="_blank" rel="nofollow noopener noreferrer">Creating a user routine and call it in a job.&nbsp;</A><BR /><A href="https://help.talend.com/pages/viewpage.action?pageId=190513200" target="_blank" rel="nofollow noopener noreferrer">Install custom component to Talend Studio</A>.&nbsp;

You need to hard code to convert a string to SHA-256.

Thanks shong, i found the code and it worked.  I'd like to share here for others if needed. 
package routines;
import java.security.MessageDigest;
import java.math.BigInteger;
public class SHA {
public static String getMD5HashedPassword(String password, String salt) {
    String sTH;
    if(password == null) {
    if(salt == null) sTH = "";
    else sTH = salt;
    }
    else {
    if(salt == null) sTH = password;
    else sTH = password + salt;
    }
   
    try {
    MessageDigest md5 = MessageDigest.getInstance("SHA-256");
    md5.update(sTH.getBytes());
    BigInteger hash = new BigInteger(1, md5.digest());
    return hash.toString(16);
    } 
    catch (Exception e) {
    return null;
    }
   }
}

Bonjour, 

can you explain how to call it from TMAP ?

routines.SHA(mystring) I suppose ... but how to pass password and salt ?

thanks in advance for your answer.

Hello everyone,

it works ... I means, it's giving a result but non significatives 0 (zeros on the left of the string) are not provided in the result ... that's an issue because my provider is hashing with different tools and they cannot match the hashed strings.

Any idea on how to get them in the result ?

regards

Damien
