(build number 6198)

Elliptic curve cryptography in TLS/SSL

All Rebex components utilizing our TLS/SSL library now support the following TLS ciphers based on Elliptic Curve Diffie-Hellman (ECDH) algorithm:

  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
  • TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA
  • TLS_ECDHE_RSA_WITH_RC4_128_SHA

Supported curves:

  • NIST P-256
  • NIST P-384
  • NIST P-521
  • Brainpool P256 R1
  • Brainpool P384 R1
  • Brainpool P512 R1
  • Curve 25519

Please note that external plugins might be needed for some of those algorithms or curves on some platforms.

Elliptic curve cryptography in SSH

All Rebex components utilizing our SSH library now support SSH key exchange algorithms based on Elliptic Curve Diffie-Hellman (ECDH) algorithm and SSH host key algorithms based on Elliptic Curve DSA (ECDSA) and Edwards-curve DSA (EdDSA) algorithms:

  • ecdh-sha2-nistp256
  • ecdh-sha2-nistp384
  • ecdh-sha2-nistp521
  • curve25519-sha256@libssh.org
  • ecdsa-sha2-nistp256
  • ecdsa-sha2-nistp384
  • ecdsa-sha2-nistp521
  • ssh-ed25519

Please note that external plugins might be needed for some of those algorithms or curves on some platforms.

Enhanced SHA-2 certificate validation on all .NET Compact Framework platforms

We still support .NET Compact Framework 2.0, 3.5 and 3.9 and Windows CE 5.0 and higher. Unfortunately, legacy versions of Windows CE won't get native support for X509 certificates signed using SHA-2 algorithms, which essentially makes the native certifiacte validator useless - it only supports SHA-1, which is getting deprecated.

As a workaround to this platform limitation, we introduce a new built-in certificate validator. It handles SHA-2 and is used by default on .NET Compact Framework platforms that lack native SHA-2 support.

Proper certificate validation on Universal Windows Platform

Support for Universal Windows Platform is still experimental, but it just got much better. We now support the platform's native certificate validation provided by Windows.Security.Cryptography.Certificates namespace. There is now no need to implement custom validators in your Windows 10 Store applications.

New OpenSSH key format support

SshPrivateKey and PrivateKeyInfo objects can read server and client keys utilizing the new OpenSSH key format (Base64-encoded keys with "BEGIN OPENSSH PRIVATE KEY" header). This format is usually used to store ED25519 or ECDSA keys.

Remote checksum calculation

Ftp, Sftp and FileTransferClient objects now feature GetChecksum methods, making it possible to retrieve a checksum or hash of a remote file (or part of it). Together with the new LocalItem.GetChecksum method, this makes it easily possible to reliably detect changed files.

Please note that this functionality is not supported by all servers (for SFTP, "file-check" extension support is required). Ftp.GetRemoteChecksum methods are now considered deprecated.

Optimized memory usage of MailMessage/MimeMessage objects

We have refactored the internals of our mail objects to make them consume less memory. Working with large messages is much more efficient now.

OAUTH authentication in EWS

The Ews object now supports OAUTH 2.0 authentication with Microsoft's Office365 and Outlook.com servers.

Mailbox synchronization in EWS

Keeping a local cache of folders and items in sync with the server is now very simple using GetUpdatedItems and GetUpdatedFolders methods.

Fine-tuning enabled ciphers in SSH

Previously, SshParameters only made it possible to enable/disable groups of ciphers. Now, it's possible to fine-tune the list of supported algorithms, including their preferred order (client-side only) using SetKeyExchangeAlgorithms, SetHostKeyAlgorithms, SetEncryptionAlgorithms and SetMacAlgorithms methods. Please note that KeyExchangeAlgorithms, HostKeyAlgorithms, EncryptionAlgorithms and MacAlgorithms properties still apply - a cipher is only used when it is enabled by both the method and property.

Disabled weak legacy ciphers in TLS/SSL

All legacy 'EXPORT1024' ciphers are now prohibited by default in addition to already-prohibited 'EXPORT' ciphers. SslAllowVulnerableSuites option can be used to enable them, but this is strongly discouraged.

Disabled weak algorithms in SSH

Several legacy ciphers are now disabled by default: diffie-hellman-group1-sha1, blowfish-ctr, blowfish-cbc, arcfour256, arcfour128, arcfour. Use SshParameters.KeyExchangeAlgorithms and SshParameters.EncryptionAlgorithms to enable them.

Weak RSA server host keys shorter than 1024 bits are now rejected by default. Use SshParameters.MinimumRsaKeySize property to specify a custom key size.

2013-08-20 Version 2013 R2 #
(build number 4981)

Terminal Emulation component supports both Telnet and SSH transport layers

Our two terminal emulation components Rebex Telnet and Rebex SSH Shell were merged into a single product called Rebex Terminal Emulation. The API has stayed the same. All users with active support contract were upgraded for free.

IMAP/SSL and POP3/SSL superseded by Rebex Secure Mail

Many users who purchased one of the budget versions of the mail component later found out they in fact needed both POP3 and IMAP capability and had to upgrade to Secure Mail. Starting today, POP3 and IMAP will no longer be available as stand-alone components. All users with active support contract were upgraded for free.

Faster ZIP archive parsing

ZIP archive parsing has been optimized, resulting in huge speed increase on slow disk drives.

2013-07-29 Version 2013 R1 #
(build number 4959)

Official support for Mono

All Rebex components now officially support Mono, an open source, cross-platform, implementation of C# and the CLR that is binary compatible with Microsoft.NET. The same assemblies that work on Windows now work on Mono in Linux or Apple's OS X as well.

Enhanced Outlook .MSG and winmail.dat/TNEF parsers

We have made numerous enhancements in MailMessage object to make it even more compatible with non-MIME message formats such as Outlook .MSG or winmail.dat/TNEF. The integrated RTF parser and RTF to HTML converter has been improved as well.

Unified FTP and SFTP item comparers

Although FtpItemCollection and SftpItemCollection objects have been derived from a shared base class since the introduction of IFtp (a common interface for SFTP and FTP/SSL), a common base class for FtpItemComparer and SftpItemComparer has been missing. In this release, we added FileSystemItemComparer to fix this inconvenience.

Terminal emulation enhancements

TerminalControl got better Ctrl+key, Alt+key and Ctrl+Alt+key support. It now also works with both singlebyte and multibyte charsets (previously, the only supported multibyte charset was UTF-8). We increased the maximum history length and enhanced copy-to-clipboard code to omit end-of-line sequences in wrapped text.

New component - Rebex Security

We released a new component called Rebex Security. It features XTS-AES encryption stream support and easy-to-use FileEncryption class with support for AES, 3DES, TwoFish and XTS-AES. Also includes PKCS #7 (CMS) API for electronic signatures and encryption of binary data using X509 certificates. Supports .NET Framework, .NET Compact Framework and Mono. Available as a standalone package or as a part of Rebex Total Pack.

2012-11-12 Version 2012 R3 #
(build number 4700)

Official support for Visual Studio 2012

All Rebex components now ship with full support for Microsoft Visual Studio 2012. Samples and tutorials were updated for a new project file format. Older Visual Studio and .NET Framework versions are still supported too.

Task-based asynchronous methods

The major change is the addition of new Task-based asynchronous methods to .NET 4.0/4.5 variant of our components. This brings our API up-to-date with the current trends and makes it possible to utilize the new await keyword available in .NET 4.5 and Visual Studio 2012. Finally, asynchronous programming became easy and seamless. Check out some of the updated samples to see this in action!

Events now using SynchronizationContext

Previously, events raised by asynchronous methods were running in a background thread, making them hard to use in GUI applications. Now, events are raised using the SynchronizationContext captured when the asynchronous method was started, which basically means the events will run on application's GUI thread, making it possible to update application's controls directly from the event code.

Simplified Connect methods

We simplified even the most common task - connecting to a server. All you have to supply to the Connect method of Ftp, Imap, Pop3 or Smtp object is the server hostname and an SslMode. The Connect method automatically chooses the port according to the communication protocol and the specified SSL mode.

Simplified custom certificate validation

We added a new ValidatingCertificate event to Ftp, Imap, Pop3 and Smtp. It makes it much easier to write custom certificate validation routines - all you have to do is add an event handler which either calls e.Accept() or e.Reject().

RTF to HTML converter

Almost all e-mail messages use HTML and/or plain text for the message body. But this is not always the case for Outlook .MSG messages and even for mail messages using the infamous winmail.dat/TNEF format. Both of these often use RTF instead of HTML, causing interoperability issues with third-party clients. Fortunately, Rebex Secure Mail users no longer have to suffer from this - we have added a RTF-to-HTML converter that converts the body of these messages into HTML, which means they can be then processed just like an ordinary e-mail!

Client certificate authentication in SFTP & SSH

Although SFTP/SSH usually use password-based or public-key-based authentication, some servers support X509 client certificate authentication as well. Unfortunately, not all servers support this, and those which do use a variety of different protocol extensions to achieve it. In this release, we have added client certificate authentication compatible with VanDyke VShell server. If it doesn't work with your server, please let us know.

High-level GZIP API

Although it was already possible to read and write GZIP files using existing Rebex.IO.Compression.Streams classes, they were not as straightforward to use as we would like. As an easy-to-use alternative, we added Rebex.IO.Compression.Gzip class with Compress and Decompress methods.

(build number 4444)

Components DLLs have been renamed

We found out that the DLL naming scheme we decided to use back in 2003 was no longer sustainable and decided to change it. Instead of Rebex.Net.Ssh.dll, Rebex.Net.SecureSocket.dll, Rebex.Net.ProxySocket.dll and Rebex.Security.dll, we now have Rebex.Common.dll and Rebex.Networking.dll. Most of the other DLLs were renamed as well during the process (Rebex.Net.Ftp.dll became Rebex.Ftp.dll, for example). We are sorry for any inconvenience this may have caused, but an alternative solution - introduction of a new DLL for shared functionality - would not be hassle-free either. Fortunately, in order to upgrade to the new version, most customers will only need to remove references to the old DLLs and add references to the new ones because the API is still backward-compatible.

New multi-file methods in Rebex SFTP and FTP/SSL

FTP/SSL and SFTP got several new methods: Upload, Download, Delete and GetItems. The first two are replacements for PutFiles/GetFiles (and support move operation in addition to copy), Delete makes it possible to delete multiple files (or even a directory tree) at once and GetItems makes it possible to retrieve a list of files for the whole directory tree in one call.

Common API for SFTP and FTP/SSL (experimental)

Lot of our customers have been asking for a common API capable of both SFTP and FTP/SSL. Even though Ftp and Sftp objects provide a very similar API, they are still two distinct classes and writing code that can use either of them was hard. Now, it got much better with the introduction of IFtp interface.

Faster Blowfish and Twofish algorithms for Rebex SFTP and Rebex SSH Shell

Bruce Schneier's Blowfish and Twofish symmetric encryption algorithms are a popular choice for SSH communication encryption. Although we have been already supporting both for a few years, we developed a new managed implementation that is substantially faster than the old one.

Compatibility enhancements in Rebex Secure Mail

We are constantly improving our mail writers and parsers to be as compatible with third-party software as possible. In this version, we added support for some embedded OLE objects in TNEF/winmail.dat e-mails (they are parsed as attachments) and enhanced our PKCS #7 (S/MIME) writer which used to have some compatibility issues with Entrust CSP. Many workarounds for badly structured messages were added as well. Rebex Secure Mail is now more compatible than ever.

Support for Time and Daytime protocols in Rebex Time

Although SNTP is a very useful protocol, it runs on top of UDP protocol which is not always available. We added support for Time and Daytime protocols which run over TCP. They don't offer the precision of SNTP, but can be useful if SNTP is simply not an option.
