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
u	01110101
n	01101110
c	01100011
o	01101111
m	01101101
m	01101101
o	01101111
n	01101110

Step 2: Group Bits into 6-bit Chunks

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

011101 010110 111001 100011 011011 110110 110101 101101 011011 110110 1110

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
010110	W
111001	5
100011	j
011011	b
110110	2
110101	1
101101	t
011011	b
110110	2
1110	4

When combined, these characters form the encoded string: "dW5jb21tb24="
