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
h	01101000
e	01100101
l	01101100
p	01110000
l	01101100
i	01101001
n	01101110
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011010 000110 010101 101100 011100 000110 110001 101001 011011 100110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
000110	G
010101	V
101100	s
011100	c
000110	G
110001	x
101001	p
011011	b
100110	m
0101	U

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