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
g	01100111
i	01101001
g	01100111
a	01100001
b	01100010
y	01111001
t	01110100
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011001 110110 100101 100111 011000 010110 001001 111001 011101 000110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
110110	2
100101	l
100111	n
011000	Y
010110	W
001001	J
111001	5
011101	d
000110	G
0101	U

When combined, these characters form the encoded string: "Z2lnYWJ5dGU="
