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
a	01100001
c	01100011
k	01101011
n	01101110
o	01101111
w	01110111
l	01101100
e	01100101
d	01100100
g	01100111
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 001101 101011 011011 100110 111101 110111 011011 000110 010101 100100 011001 110110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
001101	N
101011	r
011011	b
100110	m
111101	9
110111	3
011011	b
000110	G
010101	V
100100	k
011001	Z
110110	2
0101	U

When combined, these characters form the encoded string: "YWNrbm93bGVkZ2U="
