Title: iso verification
Post by: lumilumi on June 02, 2026, 12:18:47 AM
hi! I'm brand new to this and I was wondering if I could get some help with this part of the instructions on installation --

im trying to verify my iso before installing - but I can't get this part of the instructions to work:


https://docs.opnsense.org/manual/install.html#download-and-verification
If the checksums match, continue with the verification commands.

openssl base64 -d -in OPNsense-<filename>.<image>.sig -out /tmp/image.sig
openssl dgst -sha256 -verify OPNsense-<filename>.pub -signature /tmp/image.sig OPNsense-<filename>.<image>


I have changed the file name to actual file name -- but the command says:
cannot verify two files at once


I verified pub key and checksum 256 -- but this part of the commands won't work for me
any tips? i'm very new!
any help greatly appreciated
