Rebex .NET components 2017 R4: Virtual file systems in Rebex File Server

Virtual file systems in Rebex File Server

Rebex File Server now features a rich custom file system provider API. This can be used to implement virtual file systems, or custom file systems that store data in a database, in the cloud, or elsewhere. Additionally, the built-in mount-capable virtual file system provider makes it possible to construct virtual file systems composed from multiple unrelated providers:

// create an instance of mount-capable file system provider
var virtualFS = new MountCapableFileSystemProvider();

// create a read-write instance of the local file system provider
var homeFS = new LocalFileSystemProvider(@"c:\data\users\user01", FileSystemType.ReadWrite);  
virtualFS.Mount("/home/user01", homeFS);

// create a read-only instance of the local file system provider
var publicFS = new LocalFileSystemProvider(@"c:\data\public", FileSystemType.ReadOnly);  
virtualFS.Mount("/public", publicFS);

// use the mount-capable file system provider as server user's virtual file system

Support for CNG Key Storage Providers

Rebex Certificate class now fully supports RSA, DSA and ECDSA private keys stored in Windows CNG Key Storage Providers.

Native support for Brainpool (P-256 R1, P-384 R1, P-512 R1) and secp256k1 elliptic curves on Windows 10

Windows 10 (and Windows Server 2016) added native support for additional Elliptic Curve DSA (ECDSA) / Elliptic Curve Diffie-Hellman (ECDH) curves including secp256k1, Brainpool P-256 R1, P-384 R1 and P-512 R1, and Rebex classes can take advantage of them now (in addition to NIST P-256/P-384/P-521 curves).

Brainpool curves have already been supported by our TLS/SSL library and can be used with the following ciphers:


For earlier Windows and other operating systems, Brainpool curves are available through external plugins.
