(CkPython) SSH Auth Failure Reason (AuthenticatePwPk)This example demonstrates how to determine the failure reason for the case where both a password and private key are required for authentication. If authentication fails, was it because of an invalid private key, or an invalid password? Note: This example requires Chilkat v11.0.0 or greater.
import sys import chilkat success = False # This example assumes the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. # Load a private key to be used for SSH authentication. key = chilkat.CkSshKey() key.put_Password("key_password") success = key.FromOpenSshPrivateKey(key.loadText("qa_data/my_private_key_file")) if (success == False): print(key.lastErrorText()) sys.exit() ssh = chilkat.CkSsh() success = ssh.Connect("ssh.example.com",22) if (success == False): print(ssh.lastErrorText()) sys.exit() # Authenticate using both a password and private key. success = ssh.AuthenticatePwPk("myLogin","myPassword",key) if (success == True): print("Authentication is successful!") sys.exit() # If we get here, it means the authentication failed. # Examine the last JSON data to get information.. json = chilkat.CkJsonObject() ssh.GetLastJsonData(json) json.put_EmitCompact(False) # This is the JSON if the key is correct, but the password is incorrect: # { # "public_key_type": "rsa", # "partialAuthResult": "publickey success. continue to authenticate with password...", # "authResult": "failed", # "authFailReason": "Password is incorrect" # } # This is the JSON if the key is incorrect. We won't know if the password is also incorrect until # the key is made correct so that authentication proceeds to check the password. # { # "public_key_type": "rsa", # "authResult": "failed", # "authFailReason": "Key is incorrect" # } # To get the authResult anbd authFailReason: print("authResult: " + json.stringOf("authResult")) print("authFailReason: " + json.stringOf("authFailReason")) |
