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
w	01110111
e	01100101
s	01110011
t	01110100
m	01101101
i	01101001
n	01101110
s	01110011
t	01110100
e	01100101
r	01110010

Step 2: Group Bits into 6-bit Chunks

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

011101 110110 010101 110011 011101 000110 110101 101001 011011 100111 001101 110100 011001 010111 0010

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
110110	2
010101	V
110011	z
011101	d
000110	G
110101	1
101001	p
011011	b
100111	n
001101	N
110100	0
011001	Z
010111	X
0010	I

When combined, these characters form the encoded string: "d2VzdG1pbnN0ZXI="
