selabel_digest - Man Page

Return digest of specfiles and list of files used


#include <selinux/selinux.h>
#include <selinux/label.h>

int selabel_digest(struct selabel_handle *hnd, unsigned char **digest, size_t *digest_len,
char ***specfiles, size_t *num_specfiles);


selabel_digest() performs an operation on the handle hnd, returning the results of the SHA256 digest pointed to by digest, whose length will be digest_len. The list of specfiles used in the SHA256 digest calculation is returned in specfiles with the number of entries in num_specfiles.

To enable selabel_digest() to return this information the SELABEL_OPT_DIGEST option must be enable in selabel_open(3).

The result of selabel_digest() must not be used after selabel_close(3).

Return Value

On success, zero is returned.  On error, -1 is returned and errno is set appropriately.



No digest available (returned if SELABEL_OPT_DIGEST option not enabled).


An attempt to allocate memory failed.
