PUTTY - The server's host key is not cached in the registry cache

-
Error: "The server's host key is not cached in the registry. You have no guarantee that the server is the computer you think it is.

If you want to carry on connecting just once, without adding the key to the cache, enter "n". If you do not trust this host, press Return to abandon the connection. Store key in cache? (y/n) y" Answer: Simply run this command in your windows preferred terminal (cmd.exe etc) and agree to accept the host and store the cache: C:\Program Files (x86)\PuTTY\plink.exe -ssh [SSH USERNAME]@[SSH HOST] -P [SSH PORT] echo y | pscp -i /path/to/key/file user@remote:/tmp/file  . echo y | plink -i /path/to/key/file scripts.sh Usually you would hit “y” here, assuming the host key is correct, in order to store it in future connection.  The storage of this goes into the Registry under ...

SAML & OAuth 2.0

-
Both SAML (Security Assertion Markup Language) and OAuth 2.0 are widely used protocols for authentication and authorization in web applications, but they serve different purposes. SAML (Security Assertion Markup Language) Purpose: Primarily designed for authentication and single sign-on (SSO) . How it works: A user attempts to access a service provider (SP). The SP redirects the user to an identity provider (IdP). The IdP authenticates the user and sends a SAML assertion to the SP. The SP validates the assertion and grants access to the user. Common use cases: Enterprise applications, government services, and federated identity management systems. OAuth 2.0 Purpose: Designed for authorization , allowing users to grant third-party applications access to their data on a specific service. How it works: A user attempts to access a resource on a service provider. The SP redirects the user to the authorization server. The user grants permission to the application. The authorization s...
