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
u	01110101
r	01110010
f	01100110
a	01100001
c	01100011
e	01100101
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011100 110111 010101 110010 011001 100110 000101 100011 011001 010111 0011

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
110111	3
010101	V
110010	y
011001	Z
100110	m
000101	F
100011	j
011001	Z
010111	X
0011	M

When combined, these characters form the encoded string: "c3VyZmFjZXM="
