Using GitHub & GPG together

Fetching GPG keys

Any GitHub user account can contain GPG keys used for signed commits. To verify these signatures, your local gpg.program needs the public key.

To fetch them, just use a URL such as this: https://github.com/<ACCOUNT>.gpg

tcely

url_decode() {
    local arg ;
    if [ $# -gt 0 ]; then
        for arg; do
            printf -- '%s\n' "${arg}" ;
        done | url_decode ;
    else
        check_printf ;
        printf -- '%b\n' "$(sed -E -e 's/\+/ /g' -e 's/%([0-9a-fA-F]{2})/\\x\1/g')" ;
    fi ;
