About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: Two '=' characters are added when the input length modulo 3 equals 1. This happens because the input length leaves a remainder of 1 when divided by 3, indicating that two more bytes are needed to complete the 3-byte group. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
g	01100111
o	01101111
o	01101111
d	01100100
b	01100010
y	01111001
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011001 110110 111101 101111 011001 000110 001001 111001 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
110110	2
111101	9
101111	v
011001	Z
000110	G
001001	J
111001	5
011001	Z
01	Q

When combined, these characters form the encoded string: "Z29vZGJ5ZQ=="
