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
d	01100100
e	01100101
s	01110011
p	01110000
e	01100101
r	01110010
a	01100001
t	01110100
e	01100101
l	01101100
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011001 000110 010101 110011 011100 000110 010101 110010 011000 010111 010001 100101 011011 000111 1001

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
000110	G
010101	V
110011	z
011100	c
000110	G
010101	V
110010	y
011000	Y
010111	X
010001	R
100101	l
011011	b
000111	H
1001	k

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