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
s	01110011
y	01111001
n	01101110
c	01100011
h	01101000
r	01110010
o	01101111
n	01101110
o	01101111
u	01110101
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011100 110111 100101 101110 011000 110110 100001 110010 011011 110110 111001 101111 011101 010111 0011

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
110111	3
100101	l
101110	u
011000	Y
110110	2
100001	h
110010	y
011011	b
110110	2
111001	5
101111	v
011101	d
010111	X
0011	M

When combined, these characters form the encoded string: "c3luY2hyb25vdXM="
