java - why Tomcat check file integrity -

-

when download tomcat, installation guide says "you must verify integrity of downloaded files". want know, why?

we never check file integrity hand when download file internet, tomcat, need it. tomcat have special reason?

you should verify integrity of file download on internet; attacker may have modified in nefarious ways. verifying signature ensures you

  1. have entire file
  2. it wasn't tampered with.
