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.
