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
i	01101001
n	01101110
d	01100100
e	01100101
p	01110000
e	01100101
n	01101110
d	01100100
e	01100101
n	01101110
t	01110100

Step 2: Group Bits into 6-bit Chunks

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

011010 010110 111001 100100 011001 010111 000001 100101 011011 100110 010001 100101 011011 100111 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
010110	W
111001	5
100100	k
011001	Z
010111	X
000001	B
100101	l
011011	b
100110	m
010001	R
100101	l
011011	b
100111	n
0100	Q

When combined, these characters form the encoded string: "aW5kZXBlbmRlbnQ="
