PASTER creates private/public keypairs for the user # and a keypairs for the recipient. PASTER does NOT distribute the keypairs. # This is up to the user. But paste.interhacktive.de can be used to hand the # public keys over to the recipient. # Encrypted pastes will never be shown on website. They are private pastes # by default. # # Keyfile names are never transmitted to any server or any recipients. # They are solely for the user to easily identify the keypairs. # They can of course have names like "1234567890", "wrdlbrmpft" or "fake president" # In fact they are just filenames. So every valid filename is OK. # # Keypairs can be savely deleted at any time. (Of course no file encrypted # can be decrypted anymore ) # # the following default keypair is special in that it is not used # for encryption of pastes. It allows user to create private posts without # registering with the server which requires a vaild email # address key_filename="$USER@paster" # # This keypair is used only for pasting private posts on the server # without the need for registering with the website. # Registering is of course always possible, but needs a valid email address. # The private Key of this "special" keypair is send to the pasteserver # The client encrypts meta data with the puclic key and sends it to the server # encrpted. # With this private key the server decrypts the meta data # and is hence capable to map the paste to the user without a need # for registering with the server. # # The mapping of a private paste is done by the sha-hash of the key. # (see docs of openSSL for details ) # This way a non- registered user can give the "privat paste hash" # and the url of the paste. Without entering the key-hash the paste # cannot bee seen. # No information needs to be disclosed at any time this way. # # And of course you can use encrytion for a private paste too. # This enables the user to pass a crypted non-public paste to # another user without registering one or both of the participants. # key_store_dir will be used as a plain dir or as mountpoint for "cryfs" # depending on the value of \$use_crypted_keystore # All keypairs are stored in directory: keystore_dir="$user_conf_dir"/"keystore" # the keystore can be encrypted with "cryfs" # use_crypted_keystore= yes | no use_crypted_keystore='yes' # if use_crypted_keystore is 'yes' we need additionally # a directory where the crypted data reside cryfs_dir="$user_conf_dir"/"crydir" # version string # DO NOT EDIT version!! # is done completly automatically! version=0.1.3 programs_needed[${#programs_needed[*]}]=fold programs_needed[${#programs_needed[*]}]=tput declare -x supported_colors=$(tput colors) base03=$( tput setaf 234) base02=$( tput setaf 235) base01=$( tput setaf 240) base00=$( tput setaf 241) base0=$( tput setaf 244) base1=$( tput setaf 245) base2=$( tput setaf 254) base3=$( tput setaf 230) yellow=$( tput setaf 136) orange=$( tput setaf 166) red=$( tput setaf 160) magenta=$( tput setaf 125) violet=$( tput setaf 61) blue=$( tput setaf 33) cyan=$( tput setaf 37) green=$( tput setaf 64) isCheckWinSizeOn=$(LANG=C shopt | grep checkwinsize | awk '{print$NF}') shopt -s checkwinsize bold=$(tput bold) hbmode=$(tput dim) # turn on half-bright mode ul=$(tput smul) # begin underline mode ul_end=$(tput rmul) # exit underline mode reverse=$(tput rev) # Turn on reverse mode standout=$(tput smso) # Enter standout mode (bold on rxvt) standout_end=$(tput rmso) # Exit standout mode reset=$( tput sgr0) # Turn off all attributes ok_prefix="[${green}OK${reset}]" fail_prefix="$(tput setab 246)[${red}${bold}FAIL!$reset$(tput setab 246)]$reset" info_prefix="[${yellow}INFO$reset]" declare -x msg_indent_cols declare -x msg_indent_char declare -x msg_indent declare -x msg_width # taken from https://stackoverflow.com/questions/10060500/bash-how-to-evaluate-ps1-ps2#10060576 PS1_expanded=$(echo WrdlbrmpfdHalliGalli | bash -i 2>&1 \ | grep WrdlbrmpfdHalliGalli \ | head -1 \ | sed 's/WrdlbrmpfdHalliGalli//g') dimensions_update(){ cols=$(tput cols) lines=$(tput lines) msg_indent_cols=2 msg_indent_char=' ' msg_indent=$( while ((msg_indent_cols > i)); do printf "%s" "$msg_indent_char"; ((i++)); done; ) msg_width=$((cols - msg_indent_cols)) } dimensions_update trap dimensions_update WINCH indent_long_msg(){ echo $* | fold -s -w $msg_width | while read line; do printf "$msg_indent$line\n" done } msg(){ #printf "$msg_indent$*\n" indent_long_msg $* } msg_fail(){ printf "${msg_indent}$fail_prefix$reset $*$reset\n" } msg_ok(){ printf "$msg_indent$ok_prefix $*\n" } msg_info(){ printf "$msg_indent$info_prefix $*\n" } msg_ask(){ local answer_prefix='[' local answer_postfix=']' local i=0 local choices=$2 local numChoices=${#choices} local default=$( while (( i < numChoices )); do if [[ ${choices:i:1} =~ [A-Z] ]] ; then printf ${choices:i:1} fi ((i++)) done ) if [[ ${#default} -gt 1 ]] ; then msg_fail $( printf "$( gettext "too many default answers given.
