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
c	01100011
h	01101000
a	01100001
l	01101100
l	01101100
e	01100101
n	01101110
g	01100111
e	01100101
d	01100100

Step 2: Group Bits into 6-bit Chunks

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

011000 110110 100001 100001 011011 000110 110001 100101 011011 100110 011101 100101 011001 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
100001	h
100001	h
011011	b
000110	G
110001	x
100101	l
011011	b
100110	m
011101	d
100101	l
011001	Z
00	A

When combined, these characters form the encoded string: "Y2hhbGxlbmdlZA=="
