Verify signature of Arch Linux ISO:

$ gpg --keyserver-options auto-key-retrieve --verify archlinux-2024.12.01-x86_64.iso.sig

Alternative

To find public key that was used to sign Arch Linux ISO, run the following command:

Strips away the metadata overhead (such as memory addresses) from the Intel HEX file and retains only the raw data in the .bin file. This makes firmware file lightweight and suitable for direct loading into memory, such as for use in a bootloader or any firmware updater

$ arm-none-eabi-objcopy.exe -I ihex input.hex -O binary output.bin

By default, OpenSSL installed by Git on Windows is located at:

C:\Program Files\Git\usr\bin\openssl.exe

Follow these steps to generate a private and public key pair using OpenSSL.

Create Private Key

Run the following command to generate a 2048-bit RSA private key and save it to private_key.pem:

$ lsblk
$ sudo cryptsetup open /dev/sdb2 vaultdrive
$ mkdir -p /media/data
$ sudo mount /dev/mapper/vaultdrive /media/data
$ ranger /media
