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
i	01101001
n	01101110
t	01110100
e	01100101
r	01110010
c	01100011
h	01101000
a	01100001
n	01101110
g	01100111
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011010 010110 111001 110100 011001 010111 001001 100011 011010 000110 000101 101110 011001 110110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
010110	W
111001	5
110100	0
011001	Z
010111	X
001001	J
100011	j
011010	a
000110	G
000101	F
101110	u
011001	Z
110110	2
0101	U

When combined, these characters form the encoded string: "aW50ZXJjaGFuZ2U="
