* Add source folder keeshare for sharing with corresponding define WITH_XC_KEESHARE
* Move common crypto parts to src/crypto/ssh
* Extended OpenSSHKey
* Move filewatching to own file (currently in two related classes DelayedFileWatcher and BulkFileWatcher)
* Small improvements for style and code in several classes
* Sharing is secured using RSA-Keys which are generated on demand
* Publisher signs the container using their private key
* Client can verify the signed container and choose to decline an import,
import only once or trust the publisher and automatically import all
data of this source henceforth
* Integration of settings into Group-Settings, Database-Settings and Application-Settings
* Introduced dependency QuaZip as dependency to allow combined export of
key container and the (custom format) certificate
The previous default was to expect passphrases to be ASCII or
rather Latin-1. It would be reasonable to expect modern keys to
use UTF-8 instead.
This is a non-breaking change if passphrases only use characters
that fall within ASCII.
Fixes#2102
AES-256 uses a 32-byte (256-bit) key size. This un-breaks the loader and
tests added for AES-256-CBC and AES-256-CTR PEM keys.
* OpenSSHKey: correctly parse encrypted PEM AES-256-CBC/AES-256-CTR keys
* OpenSSHKey: use correct key derivation for AES-256
