SYNOPSIS

       #include <librecast/net.h>

       int lc_ctx_getkey(lc_ctx_t *ctx, lc_key_t *key, int type);
       int lc_ctx_setkey(lc_ctx_t *ctx, lc_key_t *key, int type);
       int lc_channel_getkey(lc_channel_t *chan, lc_key_t *key, int type);
       int lc_channel_setkey(lc_channel_t *chan, lc_key_t *key, int type);

       Compile and link with -llibrecast.

DESCRIPTION

       These functions get or set keys for a Librecast context ctx or channel chan.

       isapointertoanlc_key_tstructure.  The set functions will use this to  set  the  key  on  the  context  or
       channel, and the set functions will return a copy of the current key in this structure.

       LC_CODE_SYMM
              Symmetric key.

       LC_CODE_PUBK
