    NAME

    gss_get_mic
    
     
    gss_sign
    
     - Calculate a cryptographic message integrity code (MIC) for a
    
    message; integrity service
    
    
     
    

    SYNOPSIS

       #include <gssapi/gssapi.h>
    OM_uint32 Fo gss_get_mic Fa OM_uint32 *minor_status Fa const gss_ctx_id_t context_handle Fa gss_qop_t qop_req Fa const gss_buffer_t message_buffer Fa gss_buffer_t msg_token Fc Ft OM_uint32 Fo gss_sign Fa OM_uint32 *minor_status Fa const gss_ctx_id_t context_handle Fa gss_qop_t qop_req Fa gss_buffer_t message_buffer Fa gss_buffer_t msg_token Fc  

    DESCRIPTION

    Generates a cryptographic MIC for the supplied message, and places the MIC in a token for transfer to the peer application. The Fa qop_req parameter allows a choice between several cryptographic algorithms, if supported by the chosen mechanism.

    Since some application-level protocols may wish to use tokens emitted by gss_wrap ();
    to provide "secure framing", implementations must support derivation of MICs from zero-length messages.

    The gss_sign ();
    routine is an obsolete variant of gss_get_mic (.);
    It is provided for backwards compatibility with applications using the GSS-API V1 interface. A distinct entrypoint (as opposed to #define) is provided, both to allow GSS-API V1 applications to link and to retain the slight parameter type differences between the obsolete versions of this routine and its current form.  

    PARAMETERS

    minor_status
    Mechanism specific status code.
    context_handle
    Identifies the context on which the message will be sent.
    qop_req
    Specifies requested quality of protection. Callers are encouraged, on portability grounds, to accept the default quality of protection offered by the chosen mechanism, which may be requested by specifying GSS_C_QOP_DEFAULT for this parameter. If an unsupported protection strength is requested, gss_get_mic ();
    will return a Fa major_status of GSS_S_BAD_QOP
    message_buffer
    Message to be protected.
    msg_token
    Buffer to receive token. The application must free storage associated with this buffer after use with a call to gss_release_buffer (.);

     

    RETURN VALUES

    GSS_S_COMPLETE
    Successful completion
    GSS_S_CONTEXT_EXPIRED
    The context has already expired
    GSS_S_NO_CONTEXT
    The context_handle parameter did not identify a valid context
    GSS_S_BAD_QOP
    The specified QOP is not supported by the mechanism
