Encryption Key by combining uint32_t and byte array

[J-M-L]

@gfvalvo

Not sure if by "original example" you mean the example code I posted

no, I meant the answer in my post #4 where I used memcpy for the ask. Sorry I should have been clearer

@J-M-L

Just use memcpy()

// Copy randomnumber1 into key starting from the first byte
memcpy(key, &randomnumber1, sizeof randomnumber1);
// Copy randomnumber2 into key starting from the fifth byte
memcpy(key + sizeof randomnumber1, &randomnumber2, sizeof randomnumber2);
// Concatenate otherpartofkey at the end of key
memcpy(key + sizeof randomnumber1 + sizeof randomnumber2, otherpartofkey, sizeof otherpartofkey);
