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
c	01100011
o	01101111
s	01110011
t	01110100
e	01100101
l	01101100
l	01101100
o	01101111

Step 2: Group Bits into 6-bit Chunks

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

011000 110110 111101 110011 011101 000110 010101 101100 011011 000110 1111

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
111101	9
110011	z
011101	d
000110	G
010101	V
101100	s
011011	b
000110	G
1111	8

When combined, these characters form the encoded string: "Y29zdGVsbG8="
