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
p	01110000
o	01101111
s	01110011
t	01110100
c	01100011
o	01101111
d	01100100
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011100 000110 111101 110011 011101 000110 001101 101111 011001 000110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
000110	G
111101	9
110011	z
011101	d
000110	G
001101	N
101111	v
011001	Z
000110	G
0101	U

When combined, these characters form the encoded string: "cG9zdGNvZGU="
