The following will add a warning when you've dropped to shell from VIM. This makes it obvious when you should or shouldn't exit out, thinking you're in a VIM shell.

if [ ! -z "${VIMRUNTIME}" ]; then
    PROMPT_PRE="%F{yellow}[VIM SHELL] "
fi

The following allows for encrypting decrypting a file using yubikey

export KEYID=0x123A4E56789AB123

yubiencrypt () {
    default=~/"${1}".$(date +%s).enc
    output="${2:-$default}"
    gpg --encrypt --armor --output ${output} -r "${KEYID}" "${1}" && echo "${1} -> ${output}"
}

yubidecrypt () {
    # Must use full path for some reason
    default=$(echo "${1}" | rev | cut -c16- | rev)
    output="${2:-$default}"
    gpg --decrypt --output "${output}" "${1}" && echo "${1} -> ${output}"
