Files shared on this website are signed with signify using a cryptographic key corresponding to the year of publishing. This is done to prove their origin even when the files are downloaded from third-party sources.

The keys can be downloaded from here:

Alternatively, the same keys are announced over DNS:

To check a signed file matches the key:

#               Check signatures
#                | Use the following public key
#                |  |                          Check the following signed file
#                |  |                           |
#                V  V                           V
signify-openssh -C -p personalcompute-2025.pub -x checksums.sig
