From b1314982194c99361c2b81b3359a21d5a289fdb5 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 19 Mar 2014 02:04:29 -0600 Subject: Team pass: enable multiple keys and per directory The .gpg-id file may now have multiple keys in it, one per line. If a .gpg-id file exists inside a subdirectory, passwords inside that directory are encrypted to that/those ids. The init command has learned a -p/--path option for writing such a sub directory .gpg-id and now can take several arguments for ids. --- src/password-store.sh | 97 +++++++++++++++++++++++++++++++++------------------ 1 file changed, 63 insertions(+), 34 deletions(-) (limited to 'src') diff --git a/src/password-store.sh b/src/password-store.sh index b2e2d0c..9f733f7 100755 --- a/src/password-store.sh +++ b/src/password-store.sh @@ -6,7 +6,6 @@ umask 077 PREFIX="${PASSWORD_STORE_DIR:-$HOME/.password-store}" -ID="$PREFIX/.gpg-id" GIT_DIR="${PASSWORD_STORE_GIT:-$PREFIX}/.git" GPG_OPTS="--quiet --yes --batch --compress-algo=none" @@ -74,9 +73,39 @@ git_add_file() { git commit -m "$2" } yesno() { - read -p "$1 [y/N] " response + read -r -p "$1 [y/N] " response [[ $response == [yY] ]] || exit 1 } +set_gpg_recipients() { + gpg_recipient_args=( ) + + if [[ -n $PASSWORD_STORE_KEY ]]; then + for gpg_id in $PASSWORD_STORE_KEY; do + gpg_recipient_args+=( "-r" "$gpg_id" ) + done + return + fi + + local current="$PREFIX/$1" + while [[ $current != "$PREFIX" && ! -f $current/.gpg-id ]]; do + current="${current%/*}" + done + current="$current/.gpg-id" + + if [[ ! -f $current ]]; then + echo "You must run:" + echo " $program init your-gpg-id" + echo "before you may use the password store." + echo + usage + exit 1 + fi + + while read -r gpg_id; do + gpg_recipient_args+=( "-r" "$gpg_id" ) + done < "$current" +} + # # BEGIN Platform definable # @@ -138,32 +167,45 @@ fi case "$command" in init) reencrypt=0 + id_path="" - opts="$($GETOPT -o e -l reencrypt -n "$program" -- "$@")" + opts="$($GETOPT -o ep: -l reencrypt,path: -n "$program" -- "$@")" err=$? eval set -- "$opts" while true; do case $1 in -e|--reencrypt) reencrypt=1; shift ;; + -p|--path) id_path="$2"; shift 2 ;; --) shift; break ;; esac done - if [[ $# -ne 1 ]]; then - echo "Usage: $program $command [--reencrypt,-e] gpg-id" + if [[ $err -ne 0 || $# -lt 1 ]]; then + echo "Usage: $program $command [--reencrypt,-e] [--path=subfolder,-p subfolder] gpg-id..." exit 1 fi + if [[ -n $id_path && ! -d $PREFIX/$id_path ]]; then + if [[ -e $PREFIX/$id_path ]]; then + echo "Error: $PREFIX/$id_path exists but is not a directory." + exit 1; + fi + fi - gpg_id="$1" - mkdir -v -p "$PREFIX" - echo "$gpg_id" > "$ID" - echo "Password store initialized for $gpg_id." - git_add_file "$ID" "Set GPG id to $gpg_id." + mkdir -v -p "$PREFIX/$id_path" + gpg_id="$PREFIX/$id_path/.gpg-id" + printf "%s\n" "$@" > "$gpg_id" + id_print="$(printf "%s, " "$@")" + echo "Password store initialized for ${id_print%, }" + git_add_file "$gpg_id" "Set GPG id to ${id_print%, }." if [[ $reencrypt -eq 1 ]]; then - find "$PREFIX/" -iname '*.gpg' | while read passfile; do - gpg2 -d $GPG_OPTS "$passfile" | gpg2 -e -r "$gpg_id" -o "$passfile.new" $GPG_OPTS && + find "$PREFIX/$id_path" -iname '*.gpg' | while read -r passfile; do + passfile_dir=${passfile%/*} + passfile_dir=${passfile_dir#$PREFIX} + passfile_dir=${passfile_dir#/} + set_gpg_recipients "$passfile_dir" + gpg2 -d $GPG_OPTS "$passfile" | gpg2 -e "${gpg_recipient_args[@]}" -o "$passfile.new" $GPG_OPTS && mv -v "$passfile.new" "$passfile" done - git_add_file "$PREFIX" "Reencrypted entire store using new GPG id $gpg_id." + git_add_file "$PREFIX/$id_path" "Reencrypted password store using new GPG id ${id_print}." fi exit 0 ;; @@ -175,22 +217,6 @@ case "$command" in version exit 0 ;; -esac - -if [[ -n $PASSWORD_STORE_KEY ]]; then - ID="$PASSWORD_STORE_KEY" -elif [[ ! -f $ID ]]; then - echo "You must run:" - echo " $program init your-gpg-id" - echo "before you may use the password store." - echo - usage - exit 1 -else - ID="$(head -n 1 "$ID")" -fi - -case "$command" in show|ls|list) clip=0 @@ -254,11 +280,12 @@ case "$command" in [[ $force -eq 0 && -e $passfile ]] && yesno "An entry already exists for $path.
