What concerns should a user that expects long term privacy have over the long term privacy of their emails?
This question came to mind while reading the help associated with the SCRYPTmail help next to the PGP key strength options:
In general, should a user of encrypted email be deleting / destroying old copies of email after is reaches a certai age such as 3-5 years old?
For encrypted email service providers, should they plan on "recrypting" (double encrypting?) old email within stronger encryption as time passes?
The logic there would be similar to that of a zip file containing zip files. The newest zip using the best reasonable encryption possible and contains the older zips that had used older probably "weaker" encryption from the perspective of users at some future point in time.
The goal would be to help prevent old email from being easier to decrypt if a server is compromised or an account is subpoenaed many years after the email was sent.
