libenoch Summary

Dynamic library providing core OTP cryptography functions supporting encryption, decryption, generation and assessment.

A typedef "options_t" structure object is used as a library interface for applications:

typedef struct{

int verbose;

char devname[DEV_PATH_MAX];

char sizestr[SIZE_LEN];

char errmsg[ERR_MSG_MAXLEN];

unsigned long long int size;

int cmd_index;

int cmd_mode;

int pyx_binary;

int padout_pdotp;

FILE *input;

FILE *output;

FILE *otp;

FILE *encrypted;

int device;

char input_fsp[MAX_FSP_PATH];

char output_fsp[MAX_FSP_PATH];

char otp_fsp[MAX_FSP_PATH];

char encrypted_fsp[MAX_FSP_PATH];

} options_t;
