- reenable python 313 build
- Update to 3.5.0:
* [Feature] #982: (via #2444, which was a rebase of #2157)
Add support for AES-GCM encryption ciphers (128 and 256 bit variants).
Thanks to Alex Gaynor for the report (& for cryptography review),
Shen Cheng for the original PR, and Chris Mason for the updated PR;
plus as usual to everyone who tested the patches and reported their results!
This functionality has been tested in client mode against OpenSSH 9.0, 9.2,
and 9.6, as well as against a number of proprietary appliance SSH servers.

- Update to 3.4.0: (CVE-2023-48795, bsc#1218168)
* Transport grew a new packetizer_class kwarg for overriding the
packet-handler class used internally.
* Address CVE 2023-48795 (aka the "Terrapin Attack", a vulnerability found
in the SSH protocol re: treatment of packet sequence numbers) as follows:
+ The vulnerability only impacts encrypt-then-MAC digest algorithms in
tandem with CBC ciphers, and ChaCha20-poly1305; of these, Paramiko
currently only implements hmac-sha2-(256|512)-etm in tandem with
AES-CBC.
+ As the fix for the vulnerability requires both ends of the connection
to cooperate, the below changes will only take effect when the remote
end is OpenSSH >= 9.6 (or equivalent, such as Paramiko in server mode,
as of this patch version) and configured to use the new
"strict kex" mode.
+ Paramiko will now raise an SSHException subclass (MessageOrderError)
when protocol messages are received in unexpected order. This includes
situations like receiving MSG_DEBUG or MSG_IGNORE during initial key
exchange, which are no longer allowed during strict mode.
+ Key (re)negotiation -- i.e. MSG_NEWKEYS, whenever it is encountered --
now resets packet sequence numbers. (This should be invisible to users
during normal operation, only causing exceptions if the exploit is
encountered, which will usually result in, again, MessageOrderError.)
+ Sequence number rollover will now raise SSHException if it occurs
during initial key exchange (regardless of strict mode status).
* Tweak ext-info-(c|s) detection during KEXINIT protocol phase; the
original implementation made assumptions based on an OpenSSH
implementation detail.
- Add patch use-64-bit-maxsize-everywhere.patch:
* Use the 64-bit value of sys.maxsize.

* [Feature] #2173: Accept single tabs as field separators (in
addition to single spaces) in
<paramiko.hostkeys.HostKeyEntry.from_line> for parity with
OpenSSH’s KnownHosts parser. Patched by Alex Chavkin.

channel_timeout keyword argument to
paramiko.client.SSHClient.connect, allowing users to configure the
previously-hardcoded default value of 3600 seconds. Thanks to
@VakarisZ and @ilija-lazoroski for the report and patch, with
credit to Mike Salvatore for patch review.
* [Support] #2178: Apply codespell to the codebase, which found a
lot of very old minor spelling mistakes in docstrings. Also
modernize many instances of *largs vs *args and **kwarg vs
**kwargs. Patch courtesy of Yaroslav Halchenko, with review from
Brian Skinn.
- 3.0.0:
* [Bug]: A handful of lower-level classes (notably
paramiko.message.Message and paramiko.pkey.PKey) previously
returned bytes objects from their implementation of __str__, even
under Python 3; and there was never any __bytes__ method.
* These issues have been fixed by renaming __str__ to __bytes__ and
relying on Python’s default “stringification returns the output of
__repr__” behavior re: any real attempts to str() such objects.
* [Bug] #2165: Streamline some redundant (and costly) byte
conversion calls in the packetizer and the core SFTP module. This
should lead to some SFTP speedups at the very least. Thanks to
Alex Gaynor for the patch.
* [Bug] #2110: Remove some unnecessary __repr__ calls when handling
bytes-vs-str conversions. This was apparently doing a lot of
unintentional data processing, which adds up in some use cases –
such as SFTP transfers, which may now be significantly faster.
Kudos to Shuhua Zhong for catch & patch.
* [Support]: Drop support for Python versions less than 3.6,
including Python 2. So long and thanks for all the fish!
* [Support]: Remove the now irrelevant paramiko.py3compat module.
* [Support]: paramiko.common.asbytes has been moved to
paramiko.util.asbytes.
* [Support]: PKey.__cmp__ has been removed. Ordering-oriented
comparison of key files is unlikely to have ever made sense (the
old implementation attempted to order by the hashes of the key
material) and so we have not bothered setting up __lt__ and
friends at this time. The class continues to have its original
__eq__ untouched.
* [Support]: The behavior of private key classes’ (ie anything
inheriting from PKey) private key writing methods used to perform
a manual, extra chmod call after writing. This hasn’t been
strictly necessary since the mid 2.x release line (when key
writing started giving the mode argument to os.open), and has now
been removed entirely.
* This should only be observable if you were mocking Paramiko’s
system calls during your own testing, or similar.
* [Support] #732: (also re: #630) SSHConfig used to straight-up
delete the proxycommand key from config lookup results when the
source config said ProxyCommand none. This has been altered to
preserve the key and give it the Python value None, thus making
the Python representation more in line with the source config
file.
* [Support]: paramiko.util.retry_on_signal (and any internal uses of
same, and also any internal retries of EINTR on eg socket
operations) has been removed. As of Python 3.5, per PEP 475, this
functionality (and retrying EINTR generally) is now part of the
standard library.

blank private key data is loaded, instead of the natural result

Paramiko-adjacent codebases to correctly handle this class of
error. Credit: Nicholas Dietz.
* [Bug] #1822: (via, and relating to, far too many other issues
to mention here) Update SSHClient so it explicitly closes its
wrapped socket object upon encountering socket errors at
connection time. This should help somewhat with certain classes
of memory leaks, resource warnings, and/or errors (though we
hasten to remind everyone that Client and Transport have their
own .close() methods for use in non-error situations!). Patch

- update to 2.3.1
+ cert_support.tar.gz - missing test certificates for testsuite
* Certificate support broke the no-certificate case for Ed25519 keys
(symptom is an AttributeError about public_blob.) This went uncaught
due to cert autoload behavior (i.e. our test suite never actually ran
the no-cert case, because the cert existed!) Both issues have been fixed.
* Implement basic client-side certificate authentication
(as per the OpenSSH vendor extension.)
* Added pre-authentication banner support for the server interface
(ServerInterface.get_banner plus related support in Transport/AuthHandler.)
* Update Ed25519Key so its constructor offers the same file_obj parameter
as its sibling key classes.
* Add a gss_trust_dns option to Client and Transport to allow explicitly
setting whether or not DNS canonicalization should occur when using GSSAPI.
* Paramiko originally defaulted to zlib compression level 9
(when one connects with compression=True; it defaults to off.) This has been
found to be quite wasteful and tends to cause much longer transfers in most
cases, than is necessar
* Enhance documentation around the new SFTP.posix_rename method
so it’s referenced in the ‘standard’ rename method for increased visibility.
* Modify logic around explicit disconnect messages, and unknown-channel situations,
so that they rely on centralized shutdown code instead of running their own.
This is at worst removing some unnecessary code, and may help with some
situations where Paramiko hangs at the end of a session.
* Display exception type and message when logging auth-rejection messages
(ones reading Auth rejected: unsupported or mangled public key); previously
this error case had a bare except and did not display exactly why the key
failed.
* Ed25519 keys never got proper API documentation support; this has been fixed.

- update to 2.1.3
* Make util.log_to_file append instead of replace.
* SSHClient and Transport could cause a memory leak if there’s a connection
problem or protocol error, even if Transport.close() is called.
* Prior support for ecdsa-sha2-nistp(384|521) algorithms didn’t fully extend
to covering host keys, preventing connection to hosts which only offer
these key types and no others. This is now fixed.
* Prefer newer ecdsa-sha2-nistp keys over RSA and DSA keys during host key
selection. This improves compatibility with OpenSSH, both in terms of general
behavior, and also re: ability to properly leverage OpenSSH-modified
known_hosts files.
* The RC4/arcfour family of ciphers has been broken since version 2.0; but since
the algorithm is now known to be completely insecure, we are opting
to remove support outright instead of fixing it.
* Move sha1 above the now-arguably-broken md5 in the list of preferred MAC
algorithms, as an incremental security improvement for users whose target
systems offer both.
* Writing encrypted/password-protected private key files was silently broken
since 2.0 due to an incorrect API call
Includes a directly related fix, namely adding the ability to read AES-256-CBC
ciphered private keys (which is now what we tend to write out as it is
Cryptography’s default private key cipher.)
* Allow any type implementing the buffer API to be used with BufferedFile,
Channel, and SFTPFile. This resolves a regression introduced in 1.13
with the Python 3 porting changes, when using types such as memoryview.
* Enhance default cipher preference order such that aes(192|256)-cbc are preferred
over blowfish-cbc.
* SSHClient now requests the type of host key it has (e.g. from known_hosts)

- update to 2.1.2
* Fix a bug in server-mode concerning multiple interactive auth steps
* SSHClient now gives its internal Transport a handle on itself, preventing
garbage collection of the client until the session is closed. Without this,
some code which returns stream or transport objects without the client that
generated them, would result in premature session closure
when the client was GCd
* Avoid test suite exceptions on platforms lacking errno.ETIME
* weak how RSAKey.__str__ behaves so it doesn’t cause TypeError under Python 3.

- update to 2.1.1
* A tweak to the original patch implementing gh#398 was not fully applied,
causing calls to ~paramiko.client.SSHClient.invoke_shell to fail with
AttributeError. This has been fixed.
* Fix the implementation of PKey.write_private_key_file (this method is only
publicly defined on subclasses; the fix was in the private real
implementation) so it passes the correct params to open()
* Add an optional timeout parameter to Transport.start_clienti
<paramiko.transport.Transport.start_client> (and feed it the value of the
configured connection timeout when used within SSHClient
<paramiko.client.SSHClient>.)
* Catch AssertionError thrown by Cryptography when attempting to load bad
ECDSA keys, turning it into an SSHException.
* Add a missing .closed attribute (plus ._closed because reasons) to
ProxyCommand <paramiko.proxy.ProxyCommand>
* Make the subprocess import in proxy.py lazy so users on platforms without
it (such as Google App Engine) can import Paramiko successfully
* Fix incorrect docstring/param-list for Transport.auth_gssapi_keyex
<paramiko.transport.Transport.auth_gssapi_keyex> so it matches
the real signature.
* Add an environment dict argument to Client.exec_command

* Add support for 384- and 512-bit elliptic curve groups in ECDSA
key types (aka ecdsa-sha2-nistp384 / ecdsa-sha2-nistp521).
* Due to an earlier bugfix, less-specific Host blocks' ProxyCommand
values were overriding ProxyCommand none in more-specific Host
blocks. This has been fixed in a backwards compatible manner (i.e.
ProxyCommand none continues to appear as a total lack of any
proxycommand key in parsed config structures).
* Fix a backwards incompatibility issue that cropped up in
SFTPFile.prefetch <~paramiko.sftp_file.prefetch> re: the
erroneously non-optional file_size parameter. Should only affect
users who manually call prefetch.
* Replace PyCrypto with the Python Cryptographic Authority (PyCA)
'Cryptography' library suite. This improves security,
installability, and performance; adds PyPy support; and much more.
* Fix stalled/hung SFTP downloads by cleaning up some threading lock
issues.
* Fix a Python 3 compatibility issue when handling two-factor
authentication.
* Clean up setup.py to always use setuptools, not doing so was a
historical artifact from bygone days.
* Update the module in charge of handling SSH moduli so it's
consistent with OpenSSH behavior re: prime number selection.
* Fix up ~paramiko.ssh_exception.NoValidConnectionsError so it
pickles correctly, and fix a related Python 3 compatibility issue.

- Update to version 1.12
* #152: Add tentative support for ECDSA keys. *This adds the ecdsa
module as a new dependency of Paramiko.* The module is available at
[warner/python-ecdsa on Github](https://github.com/warner/python-ecdsa) and
[ecdsa on PyPI](https://pypi.python.org/pypi/ecdsa).
* Note that you might still run into problems with key negotiation --
Paramiko picks the first key that the server offers, which might not be
what you have in your known_hosts file.
* Mega thanks to Ethan Glasser-Camp for the patch.
* #136: Add server-side support for the SSH protocol's 'env' command
- Use local source instead of service
- Add python-ecdsa requirement; new dependency (forwarded request 208361 from posophe)

creates the shared memory map with explicit Security Attributes of the user,
which is the same technique employed by the canonical PuTTY library to avoid
permissions issues when Paramiko is running under a different UAC context
than the PuTTY Ageant process. Thanks to Jason R. Coombs for the patch.
* #100: Remove use of PyWin32 in `win_pageant` module. Module was already
dependent on ctypes for constructing appropriate structures and had ctypes
implementations of all functionality. Thanks to Jason R. Coombs for the
patch.
* #87: Ensure updates to `known_hosts` files account for any updates to said
files after Paramiko initially read them. (Includes related fix to guard
against duplicate entries during subsequent `known_hosts` loads.) Thanks to
`@sunweaver` for the contribution. (forwarded request 197218 from dirkmueller)

* Forego random padding for packets when running under `*-ctr` ciphers
* Add `SFTPClient.putfo` and `.getfo` methods to allow direct
uploading/downloading of file-like objects
* Add `timeout` parameter to `SSHClient.exec_command` for easier setting
of the command's internal channel object's timeout

- Update to version 1.9.0:
+ #97 (with a little #93): Improve config parsing of ProxyCommand directives
and provide a wrapper class to allow subprocess-driven proxy commands to be
used as sock= arguments for SSHClient.connect.
+ #77: Allow SSHClient.connect() to take an explicit sock parameter
overriding creation of an internal, implicit socket object.
- Changes from version 1.8.1:
+ #90: Ensure that callbacks handed to SFTPClient.get() always fire at least
once, even for zero-length files downloaded. Thanks to Github user @enB for
the catch.
+ #85: Paramiko's test suite overrides
unittest.TestCase.assertTrue/assertFalse to provide these modern assertions
to Python 2.2/2.3, which lacked them. However on newer Pythons such as 2.7,
this now causes deprecation warnings. The overrides have been patched to only
execute when necessary. Thanks to @Arfrever for catch & patch.
- Changes from version 1.8.0:
+ #17 ('ssh' 28): Fix spurious NoneType has no attribute 'error' and similar
exceptions that crop up on interpreter exit.
+ 'ssh' 32: Raise a more useful error explaining which known_hosts key line was
problematic, when encountering binascii issues decoding known host keys.
Thanks to @thomasvs for catch & patch.
+ 'ssh' 33: Bring ssh_config parsing more in line with OpenSSH spec, re: order of
setting overrides by Host specifiers. Specifically, the overrides now go by
file order instead of automatically sorting by Host value length. In
addition, the first value found per config key (e.g. Port, User etc)
wins, instead of the last. Thanks to Jan Brauer for the contribution.
+ 'ssh' 36: Support new server two-factor authentication option
(RequiredAuthentications2), at least re: combining key-based & password
auth. Thanks to Github user bninja.
+ 'ssh' 11: When raising an exception for hosts not listed in
