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
k	01101011
n	01101110
o	01101111
w	01110111
n	01101110

Step 2: Group Bits into 6-bit Chunks

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

011010 110110 111001 101111 011101 110110 1110

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
110110	2
111001	5
101111	v
011101	d
110110	2
1110	4

When combined, these characters form the encoded string: "a25vd24="
