Function Documentation

base32_decode2()

uint8_t * base32_decode2	(	const char *	input,
		size_t *	output_len )

Decodes a Base32-encoded string into a binary byte array.

The following was written by Chat-GPT 4o, Nov 30, 2024 This function converts a Base32-encoded string into its binary representation. It expects the input to be valid Base32 characters. If the input contains invalid characters, it prints an error message and returns NULL.

Parameters

input	A null-terminated string containing the Base32-encoded data.
output_len	A pointer to a size_t variable where the function will store the length of the decoded binary data.

Returns

A pointer to the decoded binary data as a dynamically allocated array. The caller is responsible for freeing the memory. Returns NULL if memory allocation fails or if invalid input is detected.

cloneArray()

uint8_t * cloneArray	(	const uint8_t *	original,
		size_t	length )

Function to clone a uint8_t array.

The following was written by Chat-GPT 4o, Nov 30, 2024 This function allocates memory for a new array and copies the contents of the original array into it. The size of the array to be cloned is specified by the length parameter.

Parameters

original	A pointer to the original array to be cloned.
length	The number of elements (bytes) in the original array.

Returns

A pointer to the newly allocated array containing the copied data. Returns NULL if memory allocation fails.

generateStringKey()

void generateStringKey	(	char *	keyString,
		int	length )

Generates a full string of random characters.

Parameters

keyString	Pointer for the string to hold the key
length	Length of the key, 32 when used here.

Generates a random key of a certain length and outputs it to a string pointer.
