The Generic Security Service Application Programming Interface (GSSAPI, also GSS-API) is an application programming interface for programs to access security services. The GSSAPI is an IETF standard that addresses the problem of many similar but incompatible security services in use as of 2005.

2023年3月12日 · Care must be taken when using the Kerberos security support provider (SSP) if interoperability with GSSAPI is a requirement. The following code conventions allow interoperability with GSSAPI-based applications: Windows-Compatible Names; Authentication; Message Integrity and Privacy

The GSSAPI (Generic Security Services API) allows applications to communicate securely using Kerberos 5 or other security mechanisms. We recommend using the GSSAPI (or a higher-level framework which encompasses GSSAPI, such as SASL) for secure network communication over using the libkrb5 API directly. GSSAPIv2 is specified in RFC 2743 and RFC 2744.

The GSSAPI mechanism allows you to authenticate using Kerberos V5. The mechanism was originally designed to allow for any GSS-API mechanism to be used, but problems with the protocol made it unpractical and it is today restricted for use with Kerberos V5.

Generic Security Service Application Program Interface (GSSAPI or GSS-API) is an application programming interface for programs to access security services. The GSSAPI is an IETF standard that addresses the problem of many similar but incompatible security services in use today.

GSSAPI, or Generic Security Service Application Programming Interface, is an authentication protocol used in SSH for integrating external systems like Kerberos. While this feature can enhance security in specific environments, it is often not needed for most users.

When a client wants to establish a secure connection with a server, it initiates a security context using GSSAPI. GSSAPI handles the process of selecting a security mechanism, generating cryptographic keys, and negotiating security parameters between the client and server.

The GSS-API allows a caller application to authenticate a. principal identity associated with a peer application, to delegate. rights to a peer, and to apply security services such as confidential- ity and integrity on a per-message basis. There are four stages to using the GSS-API:

GSSAPI is geared toward developers of client/server applications who wish to add strong authentication support to their protocols. It provides a generic interface and message format that can encapsulate authentication exchanges from any authentication method that has a GSSAPI-compliant library.

GSSAPI (which stands for “Generic Security Service API”) is an standard layer for interfacing with security services. While it supports multiple different mechanisms, it is most commonly used with Kerberos 5 (“krb5” for short).
