Oh, you expected me to decrypt/re-encrypt my encrypted email as I got it???
For many uses, decrypting from the wire format and re-encrypting in
the "data at rest" security format makes excellent sense. Having only
one encryption scheme for long-term storage allows easy (relatively)
upgrade and helps to ensure that the data is still accessible,
i.e. the decryption still works. I probably have a bunch of old PGP
encrypted email I can't read anymore because I don't have the secret
key, or its passphrase. If that mail had been re-encrypted in a format
that I decrypt every day, I would still be able to read the
mail. Encryption that isn't regularly exercised gets rusty.
Show me an MUA that does this, please? None of the OpenPGP-aware MUAs
I've ever used have this feature, as far as I know. I suppose I could
go out of my way to replace the encrypted email with a
re-encrypted/plaintext email.
But frankly I'd like my encryption software to just maintain the ability
to decrypt it later.
