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
b	01100010
i	01101001
o	01101111
t	01110100
e	01100101
c	01100011
h	01101000
n	01101110
o	01101111
l	01101100
o	01101111
g	01100111
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011000 100110 100101 101111 011101 000110 010101 100011 011010 000110 111001 101111 011011 000110 111101 100111 011110 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
100110	m
100101	l
101111	v
011101	d
000110	G
010101	V
100011	j
011010	a
000110	G
111001	5
101111	v
011011	b
000110	G
111101	9
100111	n
011110	e
01	Q

When combined, these characters form the encoded string: "YmlvdGVjaG5vbG9neQ=="
