PostMortem: Generates Packets of Useful Information for Partners and Dependents to be Opened Upon Death

Version: 0.4.0
Released: 2020-03-06

PostMortem works with Avendesora to produce packets of information for partners and dependents to help them carry on after your death or incapacitation. Primarily PostMortem queries Avendesora to produce an encrypted document that contains information about all of your essential accounts including security credentials such as usernames and passcodes. It also can include related pre-prepared documents such as the legal documents that establish and control your estate.

Your partners and dependents do not need PostMortem or Avendesora to access their documents, however they must be capable of using GPG and have a GPG encryption key. However, if they do use happen to use Avendesora, they can import the accounts you shared with them directly into Avendesora.

Please report all bugs and suggestions to postmortem@nurdletech.com

Getting Started

You download and install PostMortem with:

pip3 install --user postmortem

Once installed, you will need a configuration file. The file is: ~/.config/postmortem/config and should contain the following fields.

my_gpg_ids:

A string that contains an identifier for your GPG key. This could be your email address or a GPG ID. The output files will be encrypted with this key as well as the keys of the intended recipients.

sign_with:

A string that contains an identifier of the GPG key you wish to use when signing the generated archives. If not given, your archives are not signed. You will also need to specify avendesora_gpg_passphrase_account so that your key can be unlocked.

avendesora_gpg_passphrase_account:

The name of the account that holds the passphrase of the GPG signing key.

avendesora_gpg_passphrase_field:

The name of the account field that holds the passphrase of the GPG signing key. If not given, it is assumed to be a passcode field.

name_template:

A python format string that specifies how the packet directory should be named. It can include two named parameters, name and now. name is the name of a recipient and now is and Arrow time object.

recipients:

A dictionary of dictionary that contains preferences for each of the recipients.

Here is an example config file:

my_gpg_ids = 'odin@norse-gods.com'
name_template = '{name}-{now:YYMMDD}'

recipients = dict(
    frigg = dict(
        email = 'frigg@norse-gods.com',
        category = 'wife',
        extras = [
            '~/home/finances/estate
        ],
        networth = True,
    ),
    thor = dict(
        email = 'thor@norse-gods.com',
        category = 'kids',
        extras = [
            '~/home/finances/estate
        ],
    ),
    loki = dict(
        email = 'loki@norse-gods.com',
        category = 'kids',
        extras = [
            '~/home/finances/estate
        ],
    ),
)

Two encrypted files are created for each recipient, one is an encrypted text file that contains your account information, the other is an encrypted Avendesora account file. Both of these files contain the same information. Each recipient should have an email or gpg_id that is associated with a known GPG key. Each recipient should also belong to a category. Your Avendesora accounts are searched for a field named postmortem_recipients, which is a string or list. The account is included in the packet if the recipients category is contained in postmortem_recipients. extras is a list of files or directories that are also included in the packet. Finally, if networth is specified and is True, then a networth summary is also included. networth may also be a profile name for the networth command, in which case that profile is used. The networth command is available from GitHub.

Running PostMortem

You can generate a packet for a particular recipient using:

postmortem thor

This creates the encrypted file that contains the packet. The packet can be extracted with:

gpg -d -o thor-190101.tgz thor-190101.tgz.gpg
tar zxf thor-190101.tgz

or, in a single step using:

gpg -d -o - thor-190101.tgz.gpg | tar zxf -

You can have PostMortem send the packet directly using email if email is given in the configuration file using:

postmortem -s thor

Finally, if you do not specify a recipient, packets are created for all known recipients.

Importing Accounts into Avendesora

Once you have extracted the files from a packet you will see a file named avendesora_acounts.gpg. This is an Avendesora accounts file. If you use Avendesora you can import the accounts using these two steps:

  1. Copy the file into your Avendesora accounts directory. You may rename the file, but keep the extension the same. For example:

    mv avendesora_acounts.gpg ~/.config/avendesora/parents.gpg
    
  2. Edit the Avendesora accounts file and add your new file to the accounts_files list:

    vi ~/.config/avendesora/accounts_files
    

Once you have done this you may find that there are conflicting names or aliases for your Avendesora accounts. For example, if both you and your parents use Nordea bank, the name nordea might conflict. In this case you should adjust the names and aliases used in your newly imported accounts file. None of the secrets in the imported file are generated, and so change the account names in this file will change the underlying secrets.
