我正在集成我的应用程序和okta有一个单一的标志。Okta将在SAML响应中传递一些用户信息,我需要在我的应用程序中使用这些信息。因此,我们决定使用我的服务器(Apache)公钥在IDP上加密saml响应(Xml)。
现在,我正在尝试解密saml2响应,以便获得属性。
我的应用程序使用
我正在使用下面的方法来验证/解析来自okta https://github.com/fangli/django-saml2-auth的https://github.com/fangli/django-saml2-auth响应
如果saml响应没有加密,我就能够处理响应,并从中获取用户标识和用户属性。但是,一旦在okta用我的服务器公钥加密了它,我就无法用我的私钥解密。
我在应用程序中拥有的saml设置如下:
saml_settings = { 'metadata': {
"local": [ metadat_xml
],
},
'service': {
'sp': {
'endpoints': {
'assertion_consumer_service': [
(acs_url, BINDING_HTTP_REDIRECT),
(acs_url, BINDING_HTTP_POST),
(https_acs_url, BINDING_HTTP_REDIRECT),
(https_acs_url, BINDING_HTTP_POST)
],
},
'allow_unsolicited': True,
'authn_requests_signed': False,
'logout_requests_signed': True,
'want_assertions_signed': True,
'want_response_signed': False,
},
},
'key_file': "mykey.key", # private part
'cert_file': "mykey.crt", # public part
'xmlsec_binary': '/usr/bin/xmlsec1',
'encryption_keypairs': [{
'key_file': 'mykey.key',
'cert_file': 'mykey.crt',
}]
}
if 'ENTITY_ID' in settings.SAML2_AUTH:
saml_settings['entityid'] = settings.SAML2_AUTH['ENTITY_ID']
#print('entity id ' , settings.SAML2_AUTH['ENTITY_ID'])
if 'NAME_ID_FORMAT' in settings.SAML2_AUTH:
saml_settings['service']['sp']['name_id_format'] = settings.SAML2_AUTH['NAME_ID_FORMAT']
# NOTE-'NAME_ID_FORMAT is set to None above
spConfig = Saml2Config()
spConfig.load(saml_settings)
spConfig.allow_unknown_attributes = True
saml_client = Saml2Client(config=spConfig)
return saml_client那我就有
saml_client = _get_saml_client(get_current_domain(r))
resp = r.POST.get('SAMLResponse', None)
authn_response = saml_client.parse_authn_request_response(resp, entity.BINDING_HTTP_POST )这个auth_response对象在消息加密时没有返回任何内容。
在日志中,我看到下面的错误

Error: failed to decrypt file "/tmp/tmpkhxwo8s4"我不知道为什么xmlsec1命令失败了,我在这里缺少了什么。我在这里尝试过用我的私钥(自签名私钥)解密https://www.samltool.com/decrypt.php,它可以工作。
,请你在这里帮助我,让我知道我做的不对吗?
