This means that any +older server's who have not been patched for this vulnerability will be +rejected. + +To set a minimum protocol version that will only allow servers that have been +patched for `CVE 2018-0886`, set `minimum_version=5` when creating +`HttpCredSSPAuth` like so; + +``` +import requests +from requests_credssp import HttpCredSSPAuth + +credssp_auth = HttpCredSSPAuth('domain\\user', 'password', minimum_version=5) +r = requests.get("https://server:5986/wsman", auth=credssp_auth) +``` + +### Message Encryption + +You can use this library to encrypt and decrypt messages sent to and from the +server. Message encryption is done over the TLS channel that was negotiated in +the authentication stage. The below is an example of encrypting and decrypting +messages, note this is only a basic example and not a working script and the +actual implementation depends on the protocol that is reading the messages. + +```python +import requests +from requests_credssp import HttpCredSSPAuth + +# build the auth request and sent an empty message to authenticate +hostname = "server" +session = requests.Session() +session.auth = HttpCredSSPAuth('domain\\user', 'password') + +request = requests.Request('POST', "https://%s:5986/wsman" % server, data=None) +prepared_request = self.session.prepare_request(request) +response = session.send(prepared_request) + +context = session.auth.contexts[hostname] +# encrypt the message using the wrap command +message = b'hi server' +encrypted_message = context.wrap(message) + +# send the encrypted message and get the encrypted response +request = requests.Request('POST', 'https://server:5986/wsman', data=encrypted_message) +prepared_request = self.session.prepare_request(request) +response = session.send(prepared_request) + +# decrypt the encrypted response from the server +encrypted_response = response.content +decrypted_response = context.unwrap(encrypted_response) +``` + + +## Logging + +This library uses the standard Python logging facilities. Log messages are +logged to the `requests_credssp` and `requests_credssp.credssp` named loggers. + +If you are receiving any errors or wish to debug the CredSSP process you should +enable DEBUG level logs. These logs show fine grain information such as the +protocol and cipher negotiated and each CredSSP token used in the +authentication process. + + +## Backlog + +* Add support for different credential types like smart card and redirected credentials + + + + +%prep +%autosetup -n requests-credssp-2.0.0 + +%build +%py3_build + +%install +%py3_install +install -d -m755 %{buildroot}/%{_pkgdocdir} +if [ -d doc ]; then cp -arf doc %{buildroot}/%{_pkgdocdir}; fi +if [ -d docs ]; then cp -arf docs %{buildroot}/%{_pkgdocdir}; fi +if [ -d example ]; then cp -arf example %{buildroot}/%{_pkgdocdir}; fi +if [ -d examples ]; then cp -arf examples %{buildroot}/%{_pkgdocdir}; fi +pushd %{buildroot} +if [ -d usr/lib ]; then + find usr/lib -type f -printf "/%h/%f\n" >> filelist.lst +fi +if [ -d usr/lib64 ]; then + find usr/lib64 -type f -printf "/%h/%f\n" >> filelist.lst +fi +if [ -d usr/bin ]; then + find usr/bin -type f -printf "/%h/%f\n" >> filelist.lst +fi +if [ -d usr/sbin ]; then + find usr/sbin -type f -printf "/%h/%f\n" >> filelist.lst +fi +touch doclist.lst +if [ -d usr/share/man ]; then + find usr/share/man -type f -printf "/%h/%f.gz\n" >> doclist.lst +fi +popd +mv %{buildroot}/filelist.lst . +mv %{buildroot}/doclist.lst . + +%files -n python3-requests-credssp -f filelist.lst +%dir %{python3_sitelib}/* + +%files help -f doclist.lst +%{_docdir}/* + +%changelog +* Thu Mar 09 2023 Python_Bot <Python_Bot@openeuler.org> - 2.0.0-1 +- Package Spec generated @@ -0,0 +1 @@ +c6bf9dfb8f54d8615acaddd7a01919ff requests-credssp-2.0.0.tar.gz |
