NAME¶

knet_handle_crypto - set up packet cryptographic signing & encryption

SYNOPSIS¶

#include <libknet.h>

int knet_handle_crypto(


    knet_handle_t                    knet_h,


    struct knet_handle_crypto_cfg   *knet_handle_crypto_cfg
);

DESCRIPTION¶

knet_handle_crypto

knet_h - pointer to knet_handle_t

knet_handle_crypto_cfg - pointer to a knet_handle_crypto_cfg structure see knet_handle_crypto_set_config(3) for details.

Implementation notes:

knet_handle_crypto(3) is now a wrapper for knet_handle_crypto_set_config(3) and knet_handle_crypto_use_config(3) with config_num set to 1.

STRUCTURES¶

Structure passed into knet_handle_set_crypto_config() to determine the crypto options to use for the current communications handle 

struct knet_handle_crypto_cfg {




    char           crypto_model[16];              /* Model to use. nss, openssl, etc */



    char           crypto_cipher_type[16];        /* Cipher type name for encryption. aes 256 etc */



    char           crypto_hash_type[16];          /* Hash type for digest. sha512 etc */



    unsigned char  private_key[KNET_MAX_KEY_LEN]; /* Private key */



    unsigned int   private_key_len;               /* Length of private key */
};

RETURN VALUE¶

knet_handle_crypto returns:

0 on success

-1 on error and errno is set.

-2 on crypto subsystem initialization error. No errno is provided at the moment (yet).
