Como verificar as assinaturas do meu site

Mudança na assinatura GPG do meu website
Não me lembro exatamente mas acredito que a pelo menos dois anos eu assino as páginas HTML do meu site com GPG, faço isso para praticar soberania, autenticidade até mesmo promover ferramentas que auxiliam na privacidade.
Inicialmente eu deixava a assinatura GPG embutida no próprio conteúdo HTML, por exemplo:

That truth alone is enough to keep you moving forward.">

Sabe aquela sensação de que algo não está certo? Pois é, ter a assinatura embutida nos meus arquivos HTML sempre me incomodou um pouco. Apesar de ser super prático validar a assinatura com um comando simples, tipo curl https://adlermedrado.com.br/missives/what-id-tell-my-23-year-old-self/ | gpg —verify, a ideia de ter a assinatura “colada” no arquivo original me incomodava. Parecia que o arquivo não era mais o original, né?
