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
c	01100011
o	01101111
n	01101110
g	01100111
r	01110010
e	01100101
s	01110011
s	01110011
m	01101101
a	01100001
n	01101110

Step 2: Group Bits into 6-bit Chunks

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

011000 110110 111101 101110 011001 110111 001001 100101 011100 110111 001101 101101 011000 010110 1110

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
111101	9
101110	u
011001	Z
110111	3
001001	J
100101	l
011100	c
110111	3
001101	N
101101	t
011000	Y
010110	W
1110	4

When combined, these characters form the encoded string: "Y29uZ3Jlc3NtYW4="
