Highlights

  • Add DownloadFileAsync and UploadFileAsync to SftpClient (#1634)
  • Much improved performance of SftpFileStream in consecutive read (e.g. SftpFileStream.CopyTo) scenarios (#1705)

Breaking changes:

  • SftpFileStream previously had some incomplete synchronisation for multi-threaded access, but was not advertised nor fully functioning as thread safe. This synchronisation was removed in #1705. When accessing an SftpFileStream instance from multiple threads simultaneously, ensure there exists appropriate synchronisation.
  • SftpClient.CreateText and WriteAll{Bytes/Text/Lines} were changed in #1686 to truncate the file before writing if it exists, to align with the equivalent methods on System.IO.File. Given that the prior behaviour was 14 years old, the change treads the line between breaking change and bug fix.
  • IEnumerable<string> ReadLines on SftpClient was updated in #1681 to download and yield lines during enumeration rather than reading them all up front and returning the result. This means that the connection must be active during enumeration. When storing the result of ReadLines for later use, consider using string[] ReadAllLines instead.

@Rob-Hague Rob-Hague released this 11 Nov 21:40
2024.2.0
74d4364

New features

  • Add support for PKCS#8 private key files
  • Add additional async overloads on SftpClient
  • Add support for OpenSSH certificates
  • Add support for chacha20-poly1305@openssh.com cipher algorithm
  • Increase support for aes*-gcm@openssh.com and zlib@openssh.com on lower targets

This release takes a dependency on BouncyCastle in an effort to eliminate primitive crypto code from the library. It also takes a dependency on System.Formats.Asn1 on lower targets.

Breaking changes

  • A number of legacy algorithms were dropped in #1442
  • The implementation of DSA was changed from using handwritten code to using System.Cryptography in #1458. See the PR description for behaviour changes this could cause.
  • Renci.SshNet.Common.BigInteger was deleted and its uses replaced with System.Numerics.BigInteger in #1469
  • Renci.SshNet.Common.DerData and Renci.SshNet.Common.ObjectIdentifier were deleted in #1490 and uses replaced with System.Formats.Asn1
  • See the full API diff at the end

This commit was created on GitHub.com and signed with GitHub’s verified signature.
GPG key ID: B5690EEEBB952194

Learn about vigilant mode.

New features:

  • Add support for aes*-gcm@openssh.com cipher algorithms on .NET 6+
  • Add cancellation of SshCommand via signals
  • Add SshCommand.ExecuteAsync
  • Add support for zlib@openssh.com compression algorithm on .NET 6+

Breaking changes:

  • SshCommand.ExitStatus was changed in #1423 from returning int to returning int? to reflect the fact that an exit status may not always be returned.
  • PipeStream (which provides the implementation of SshCommand.OutputStream and ExtendedOutputStream) was rewritten in #1399 to fix a number of bugs and become more "stream-like". As such:
    • It may now block where previously it may have returned 0 prematurely
    • It may now return partial data where previously it may have blocked until a certain amount of data was available.
    • The properties BlockLastReadBuffer and MaxBufferLength have been removed.
  • CommandAsyncResult was deleted in #1426
  • RsaCipher, AsymmetricCipher and CipherDigitalSignature were deleted in #1373
  • Encrypt/DecryptBlock were moved down from SymmetricCipher to BlockCipher in #1369
  • The previously nonfunctional ZlibStream was deleted and the API of Compressor was changed in #1326
  • SftpFileSytemInformation was renamed to SftpFileSystemInformation in #1425
  • See the full API diff at the end

Fixes

General

  • Support LF as line ending for banner and identification string

    Even though RFC 4253 requires that an identification string MUST be terminated by a carriage return and line feed, this fix restores support for banners and identification strings that are only terminated by a line feed.
    This is a workaround for an issue in version 7.4 of OpenSSH which was fixed in version 7.5.

    Fixes issue #761.

Feedback

Target framework support

While our list of supported target frameworks is impressive, it does come with a cost. Some of these target frameworks are no longer supported by Microsoft and even required software that is no longer available for download.

We'd like to gather feedback from our users through this issue to learn how important it is to continue supporting all these target frameworks.
