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
s	01110011
i	01101001
n	01101110
k	01101011
i	01101001

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 110110 100101 101110 011010 110110 1001

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
000110	G
010101	V
101100	s
011100	c
110110	2
100101	l
101110	u
011010	a
110110	2
1001	k

When combined, these characters form the encoded string: "aGVsc2lua2k="
