About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: Two '=' characters are added when the input length modulo 3 equals 1. This happens because the input length leaves a remainder of 1 when divided by 3, indicating that two more bytes are needed to complete the 3-byte group. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
e	01100101
x	01111000
p	01110000
r	01110010
e	01100101
s	01110011
s	01110011
i	01101001
v	01110110
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011001 010111 100001 110000 011100 100110 010101 110011 011100 110110 100101 110110 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
010111	X
100001	h
110000	w
011100	c
100110	m
010101	V
110011	z
011100	c
110110	2
100101	l
110110	2
011001	Z
01	Q

When combined, these characters form the encoded string: "ZXhwcmVzc2l2ZQ=="
