Multisignature or Multi-password File I want to create a file that I could give to 3 trusted friends, and allow any two of them to decrypt it when together (or in sequence when not physically in the same place).  This is similar to a multi-signature crypto wallet, but I just want to do it with a file.  

The use case is to create a document that would contain my sensitive passwords, bank accounts, life insurance etc... in the event of death or illness.  I would give it to three people in advance.
This is precisely the domain of secret sharing, of which there are various popular schemes like Shamir's secret-sharing scheme, and there are many widely available implementations of it in various forms which you can find with exactly those keywords.
