Do you have a will? Issues such as who will inherit copyright ownership of your work should be handled there. As for passwords, keys and so on, you can put all that into a single archive. (eg. regularly export your password manager, put any private keys you want to pass on, instructions for how to use them, etc) Encrypt the tarball/zip file with a symmetric key. Then you can use Shamir's Secret Sharing Scheme to split up the key so that a certain threshold of key holders is required to access the data (eg. Any 2 of 4): http://point-at-infinity.org/ssss/ http://point-at-infinity.org/ssss/ Distribute the parts of the key to your heirs. Leave instructions in your will so your heirs can locate the encrypted file when the time comes.
