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
b	01100010
s	01110011
t	01110100
r	01110010
a	01100001
c	01100011
t	01110100

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 001001 110011 011101 000111 001001 100001 011000 110111 0100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
001001	J
110011	z
011101	d
000111	H
001001	J
100001	h
011000	Y
110111	3
0100	Q

When combined, these characters form the encoded string: "YWJzdHJhY3Q="
