Well, this evening I added some letters inadvertently inside a PGP message, because the touchpad shifted to cursor to an encrypted paragraph. If I saved the file, the encrypted paragraph would have become un-decryptable (I tested this: decrypting no longer is possible). Unfortunately I won't always realise what happened, e.g. if I don't watch while dictating into a speech recognition (Dragon Nat. Speak.). And the encrypted parts are not needed often. So the destroyed PGP message might make it into my backups and if I try to encrypt it a year later...
