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.
