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
t	01110100
r	01110010
a	01100001
o	01101111
r	01110010
d	01100100
i	01101001
n	01101110
a	01100001
r	01110010
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011001 010111 100001 110100 011100 100110 000101 101111 011100 100110 010001 101001 011011 100110 000101 110010 011110 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
010111	X
100001	h
110100	0
011100	c
100110	m
000101	F
101111	v
011100	c
100110	m
010001	R
101001	p
011011	b
100110	m
000101	F
110010	y
011110	e
01	Q

When combined, these characters form the encoded string: "ZXh0cmFvcmRpbmFyeQ=="
