MD5 hash function (md5)

Description

Creates the MD5 hash as a byte array of the given string.

How does it work in the search window?

Select Create column in the search window toolbar, then select the MD5 hash function operation. You need to specify one argument:

The data type of the values in the new column is boxar(int1).

Example

The examples in this article use values in a data table generated from the following CSV file.

If you want to try the example for yourself, download the file and upload it to your domain clicking Data upload in the navigation pane. Name the new table my.upload.sample.data and select Current date as Date parsing type. Learn more about uploading data in Uploading log files.

After receiving the confirmation message, you can access the table from the Finder, selecting my → upload → sample → data. When you upload data from a file, all the information is included in a single column called message. To split the values into different columns, you can use the Split operation. Click Toggle Query Editor in the search window toolbar and paste the following LINQ query to save time:

from my.upload.sample.data
select split(message, ";", 11) as strings
where strings = "abc" or strings = "data" or strings = "hello" or strings = "hello world" or strings = "query"

We want to transform the value in the strings column into MD5 hashes. To do it, we will create a new column using the MD5 hash function operation. Let's call the new column md5Hash.

The arguments needed to create the new column are:

• String - strings column

Click Create column and you will see the following result:

How does it work in LINQ?

Use the operator select... as...  and add the operation syntax to create the new column. This is the syntax for the MD5 hash function operation:

• md5(string)

Example

You can copy the following LINQ script and try the above example on the my.upload.sample.data table. 

from my.upload.sample.data
select split(message, ";", 11) as strings
  where strings = "abc" or strings = "data" or strings = "hello" or strings = "hello world" or strings = "query"
  select md5(strings) as md5Hash
