Threshold encryption #323

Closed selfuryon closed 2 years ago

selfuryon commented 2 years ago

This is a feature request. Currently, rage can encrypt the same file key (which used as the key to encrypt the file) with several recipients. How about add to possibility to encrypt/decrypt with threshold cryptography: for example, use Shamir for dividing file key between several recipients, so we need several recipients to decrypt a box?

This could definitely be implemented as an age plugin!

Ok, I'll try to do that
