About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: One '=' character is added when the input length modulo 3 equals 2. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
o	01101111
u	01110101
t	01110100
s	01110011
t	01110100
a	01100001
n	01101110
d	01100100
i	01101001
n	01101110
g	01100111

Step 2: Group Bits into 6-bit Chunks

The binary string is grouped into 6-bit chunks for Base64 encoding:

011011 110111 010101 110100 011100 110111 010001 100001 011011 100110 010001 101001 011011 100110 0111

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011011	b
110111	3
010101	V
110100	0
011100	c
110111	3
010001	R
100001	h
011011	b
100110	m
010001	R
101001	p
011011	b
100110	m
0111	c

When combined, these characters form the encoded string: "b3V0c3RhbmRpbmc="
