Read second Line of File in C - c

Question

So, I programmed a Cesar Encryption that saves the Position of "Space" Characters in the Second Line of the encryptet File with Numbers (like that:
HMEQSRHLMIV //Encryptet Text (here is Enter normally)
7 //Number where the Space Char is
)
My Problem now is, that when I read the String with fgets(), but it only reads until \n, so how do i get the second Line of the File?
here is my code if that helps.
#include <stdio.h>
#include <stdbool.h>
#define asize 80
void deleteEnter(char[]);
void decrypt(char[], int, char[]);
int main() {
char Message[asize] = {0};
int code = 0;
char encMessageFile[asize + 4] = {};
char encMessage[asize] = {};
char MessageFile[asize] = {};
FILE *fp;
FILE *fp2;
bool open = false;
printf("Gib die verschluesselte Datei an: \t");
fgets(encMessageFile,asize + 4, stdin);
deleteEnter(encMessageFile);
fp = fopen(encMessageFile, "r");
do {
if (fp == NULL) {
printf("\nEs wurde keine Datei gefunden die so heisst\n");
open = false;
fclose(fp);
} else {
open = true;
}
} while (open == false);
fgets(encMessage,asize,fp);
printf("\nGib den Code zum entschluesseln ein: \t");
scanf("%i", &code);
decrypt(encMessage, code, Message);
for (int i = 0; i < asize + 4; ++i) {
if (encMessageFile[i] == '.' && encMessageFile[i + 1] == 'e' && encMessageFile[i + 2] == 'n' && encMessageFile[i + 3] == 'c' && encMessageFile[i + 4] == '\0') {
for (int j = 0; j < i; j++) {
if (encMessageFile[j] != '\0') {
MessageFile[j] = encMessageFile[j];
MessageFile[j + 1] = '\0';
}
}
i = asize + 4;
}
}
fp2 = fopen(MessageFile, "w");
fputs(Message, fp2);
fclose(fp2);
fclose(fp);
remove(encMessageFile);
}
void deleteEnter(char encMessage[]){
for (int i = 0; i < asize; i++) {
if (encMessage[i] == '\0') {
i = asize;
} else if (encMessage[i] == '\n'){
encMessage[i] = '\0';
i = asize;
}
}
}
void decrypt(char encMessage[], int code, char Message[]) {
int a = code % 26;
int LeerPos[asize] = {0};
for (int k = 0; k < asize; k++) {
if (encMessage[k] == '\n'){
for (int i = 0; i < asize; ++i) {
if (encMessage[k + i] != '\0') {
LeerPos[i] = encMessage[k + i] - 80;
} else {
i = asize;
}
}
encMessage[k] = '\0';
}
}
for (int i = 0; i < asize; i++) {
if (encMessage[i] == '\0') {
i = asize;
} else {
for (int j = 0; j < a; j++) {
encMessage[i] = encMessage[i] - 1;
if (encMessage[i] < 'A' && encMessage[i] > 'A' - 2) {
encMessage[i] = 'Z';
}
}
}
}
int x = 0;
for (int l = 0; l < asize; l++) {
for (int i = 0; i < asize; i++) {
if (l == LeerPos[i]) {
Message[l] = ' ';
x++;
} else {
Message[l] = encMessage[l - x];
}
}
}
}
I expect, that the Program after the Decryption the Message is "DIAMOND HIER"
Because a User wantet that I post the Encryption too, here it is:

int laenge(char[]); //input pointeranzleer
void encrypt(char[], int);
void Ausgabe(char[], char[], int[]);
//i abspeichern. for schleife in dritte array und array+1 und i++
