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
a	01100001
l	01101100
p	01110000
h	01101000
a	01100001
b	01100010
e	01100101
t	01110100

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 110001 110000 011010 000110 000101 100010 011001 010111 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
110001	x
110000	w
011010	a
000110	G
000101	F
100010	i
011001	Z
010111	X
0100	Q

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