Changelog

Sourced from dartssh2's changelog.

[2.22.0] - 2026-07-03

• Added optional handshakeTimeout and authTimeout to SSHClient to limit connection negotiation and user authentication times #182. Thanks [@​GT-610].

[2.21.1] - 2026-07-02

• Fixed an SSHTransport busy-loop (100% CPU / ANR) that occurred when a partial packet remained in the read buffer #179. Thanks [@​vicajilau].

[2.21.0] - 2026-07-01

• Added SSHSession.waitForExit({Duration? timeout}) to await remote process exit status with an optional timeout #176. Thanks [@​GT-610].
• Hardened SOCKS5 dynamic forwarding (half-close streaming, dialing guards, timeout cancellation, malformed UTF-8 decoding, and buffer limits) #175. Thanks [@​GT-610].
• Hardened SSH agent channel frame validation (rejecting empty or oversized frames) and fallback RSA signature type checks #175. Thanks [@​GT-610].
• Improved EC private key parsing with proper ASN.1 OID curve detection, public point derivation validation, and robust comments decoding #175. Thanks [@​GT-610].

[2.20.0] - 2026-06-30

• BREAKING: Bumped the minimum Dart SDK constraint to 3.0.0 #23. Thanks [@​vicajilau].
• BREAKING: Declared OpenSSHKeyPair as a mixin class to comply with Dart 3.0 class modifier rules #23. Thanks [@​vicajilau].
• Offloaded all cryptographic key exchange (KEX) calculations to background isolates using Isolate.run on platforms that support it, preventing the Flutter main thread from blocking/freezing during connection #23. Thanks [@​vicajilau].
• Refactored internal key exchange isolate communication payloads (X25519, NIST Curves, DH) to use Dart 3.0 type-safe Records #23. Thanks [@​vicajilau].

[2.19.0] - 2026-06-30

• Added tolerant HTTP-date parsing to accept all RFC 7231 §7.1.1.1 HTTP-date formats (IMF-fixdate, RFC 850, asctime) for HTTP response headers #170. Thanks [@​GT-610].
• Added chunked transfer-encoding decoding for HTTP response bodies according to RFC 7230 §4.1, improving interoperability with HTTP/1.1 servers #171. Thanks [@​GT-610].
• Added support for OpenSSH's [email protected] SFTP extension to perform atomic renames with POSIX semantics (replace destination if it exists) when advertised by the server #172. Thanks [@​GT-610].
• Added SftpFile.downloadToRandomAccess to download a remote file directly into a dart:io RandomAccessFile using out-of-order pipelined writes, maximizing download performance on high-latency links #173. Thanks [@​GT-610].
• Fixed a connection drop bug during AEAD (AES-GCM) decryption caused by incorrect padding length validation offset calculation #168. Thanks [@​nuclear06].
