Hi,

That's normal. The concept of a "web of trust" suffers from the fact
that most people which i know good enough to trust them in general
have no idea of PGP and thus are not really trustworthy in special.
  https://en.wikipedia.org/wiki/Web_of_trust

The best verification you can get outside the web of trust is the
key fingerprint which must match one of the published fingerprints on
  https://www.debian.org/CD/verify
I deem them trustworthy because they did not change in years.

(Cryptographers might object that old keys are poor keys. But they will
also be right with telling you that cryptography is a minefield and thus
amateurs like us should stay away from it.)

Shell commands "sha1", "sha256", and "sha512" were somewhere defined to
actually be runs of program /usr/bin/openssl with the checksum algorithms
given by the command names.

Usually people get told to use shell commands "sha256sum" and "sha512sum"
which are supposed to run the programs /usr/bin/sha256sum and
/usr/bin/sha512sum from package "coreutils".

In order to find out from where the "alias" definitions stem, you will
have to check the startup scripts of your shell. Like ~/.bashrc .


Have a nice day :)
