  Key Concepts: 
  A checksum is a numerical value used to verify the integrity of data. In the context of SAP's CA-GTF-DRT Data Retention Tool, a checksum is used to ensure that the data stored in the system is not corrupted or tampered with. It is calculated by taking the sum of all the bytes in a file and then dividing it by a predetermined number. The result is then compared to a stored value to determine if the data has been modified.
  
  How to use it: 
  In order to use checksums with SAP's CA-GTF-DRT Data Retention Tool, you must first generate a checksum for each file that you wish to store in the system. This can be done using a variety of tools, such as MD5sum or SHA1sum. Once you have generated the checksums, you must store them in the system along with the files. When you need to verify that the data has not been modified, you can compare the stored checksum with the newly generated one. If they match, then you can be sure that the data has not been tampered with.
  
  Tips & Tricks: 
  When generating checksums for files stored in SAP's CA-GTF-DRT Data Retention Tool, it is important to use a secure algorithm such as MD5 or SHA1. These algorithms are more secure than other methods and will help ensure that your data
