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
d	01100100
o	01101111
c	01100011
b	01100010
o	01101111
o	01101111
k	01101011

Step 2: Group Bits into 6-bit Chunks

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

011001 000110 111101 100011 011000 100110 111101 101111 011010 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
000110	G
111101	9
100011	j
011000	Y
100110	m
111101	9
101111	v
011010	a
11	w

When combined, these characters form the encoded string: "ZG9jYm9vaw=="
