man gss_decapsulate_token (3): API function

SYNOPSIS

#include <gss.h>

OM_uint32 gss_decapsulate_token(gss_const_buffer_t input_token, gss_const_OID token_oid, gss_buffer_t output_token);

ARGUMENTS

gss_const_buffer_t input_token: (buffer, opaque, read) Buffer with GSS-API context token.
gss_const_OID token_oid: (Object ID, read) Expected object identifier of token.
gss_buffer_t output_token: (buffer, opaque, modify) Decapsulated token data;
caller must release with gss_release_buffer().

DESCRIPTION

Remove the mechanism-independent token header from an initial GSS-API context token. Unwrap a buffer in the mechanism-independent token format. This is the reverse of gss_encapsulate_token(). The translation is loss-less, all data is preserved as is. This function is standardized in RFC 6339.

RETURN VALUE

`GSS_S_COMPLETE`: Indicates successful completion, and that output parameters holds correct information.

`GSS_S_DEFECTIVE_TOKEN`: Means that the token failed consistency checks (e.g., OID mismatch or ASN.1 DER length errors).

`GSS_S_FAILURE`: Indicates that decapsulation failed for reasons unspecified at the GSS-API level.
