OpenBSD does provide hash keys to verify the integrity of the ISO files you download when you make your media for OpenBSD 6.1. That is what I did when I burned the OpenBSD 6.1 AMD64 iso to a DVD.

It is possible to have a MITM with modified copies if someone cares enough to spend the money/effort to do that. While you may think such a thing could never happen, perhaps the future will determine otherwise.

Do you read the OpenBSD documentation? One thing I have learned from using BSD UNIX is that the projects always expect you to read the documentation before asking questions. The below text is straight out of the INSTALL.amd64 file which is provided with OpenBSD 6.1. Below it lists the SHA256 and SHA256.sig which contain the hash values to verify install61.iso I downloaded.


INSTALL.amd64 Installation notes; this file.

SHA256 Output of the cksum(1) program using the option
-a sha256, usable for verification of the
correctness of downloaded files.

SHA256.sig The above file, signed with the OpenBSD signing key
for the 6.1 release, usable for verification of the
integrity of the above file, and thus of the
downloaded files.

miniroot61.fs A miniroot filesystem image to be used if you
for some reason can't or don't want to use the
ramdisk installation method.
It can be copied to a small USB key to start the install.

floppy61.fs The standard amd64 boot and installation floppy;
see below.

pxeboot amd64-specific second-stage PXE bootstrap (for
network installs); see below.

*.tgz amd64 binary distribution sets; see below.

bsd A stock GENERIC amd64 kernel which will be
installed on your system during the install.

bsd.mp A stock GENERIC.MP amd64 kernel, with support for
multiprocessor machines, which can be used instead
of the GENERIC kernel after the install.

bsd.rd A compressed RAMDISK kernel; the embedded
filesystem contains the installation tools.
Used for simple installation from a pre-existing
system.

install61.iso The amd64 boot and installation CD-ROM image,
which contains the base and X sets, so that install
or upgrade can be done without network connectivity.

install61.fs A boot and installation image which contains
the base and X sets. An install or upgrade can be
