About Base32

Base32 is an encoding method that uses printable ASCII characters.

In Base32, data is divided into 5 bits and converted into alphanumeric characters (A-Z, 2-7). Converts every 8 characters, and if the last is less than 8 characters, pad with the equal symbol (=).

The conversion table for Base32 characters is as follows.

5-bit data	Base32 character
00000	A
00001	B
00010	C
00011	D
00100	E
00101	F
00110	G
00111	H
01000	I
01001	J
01010	K
01011	L
01100	M
01101	N
01110	O
01111	P
10000	Q
10001	R
10010	S
10011	T
10100	U
10101	V
10110	W
10111	X
11000	Y
11001	Z
11010	2
11011	3
11100	4
11101	5
11110	6
11111	7

For example, if you convert "Hello!" with Base32, it will be as follows.

1. Make it a binary representation.

01001000 01100101 01101100 01101100 01101111 00100001  (For US-ASCII / UTF-8)

2. Separate every 5 bits. If it is less than 5 bits, pad it with "0" at the end.

01001 00001 10010 10110 11000 11011 00011 01111 00100 00100

3. Convert to characters using a conversion table. Convert every 8 characters, and if it is less than 8 characters, pad the end with "=".

4. Connect all the characters to get the Base32 conversion result.
