NAME

       lc_ctx_set_sym_key,  lc_ctx_set_pub_key,  lc_channel_set_sym_key, lc_channel_set_pub_key -
       set Librecast channel encoding keys

LIBRARY

       Librecast library (liblibrecast, -llibrecast)

SYNOPSIS

       #include <librecast/net.h>

       int lc_ctx_set_sym_key(lc_ctx_t *ctx, unsigned char *key, size_t len);
       int lc_ctx_set_pub_key(lc_ctx_t *ctx, unsigned char *key, size_t len);
       int lc_channel_set_sym_key(lc_channel_t *chan, unsigned char *key, size_t len);
       int lc_channel_set_pub_key(lc_channel_t *chan, unsigned char *key, size_t len");"

       Compile and link with -llibrecast.

DESCRIPTION

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

       The lc_ctx_set_sym_key() function sets a symmetric  key  of  length  len  on  a  Librecast
       context.  This  key will be used by default by any channels subsequently created using the
       context. Any existing channels will retain their existing key.

       The lc_ctx_set_pub_key() function sets a public key of length len on a Librecast  context.
       This  key  will be used by default by any channels subsequently created using the context.
       Any existing channels will retain their existing key.

       The lc_channel_set_sym_key() function sets a symmetric key of length len  on  a  Librecast
       channel.

       The  lc_channel_set_pub_key()  function  sets  a  public  key of length len on a Librecast
       channel.

RETURN VALUE

       These functions return zero on success. On error, -1 is  returned  and  errno  is  set  to
       indicate the error.

ERRORS

       EINVAL Invalid argument.
