- 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)
and does not consider a different type to be a “Missing” host key. This fixes
a common case where an ECDSA key is in known_hosts and the server also has
