Ascertaining Linux ISO checksums

Laszlo Nemes

TS Rookie
Please help me with answers on the following topiv:

I successfully downloaded iso files for centos-7 and I also get the SHA-256 checksums with them. How can I ascertain (before installing CentOS) that these checksums are OK. There are no PGP numbers on the particular download mirror I am using here in Budapest. I read on the web that pgp numbers are needed
