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
t	01110100
h	01101000
e	01100101
o	01101111
r	01110010
e	01100101
t	01110100
i	01101001
c	01100011
a	01100001
l	01101100

Step 2: Group Bits into 6-bit Chunks

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

011101 000110 100001 100101 011011 110111 001001 100101 011101 000110 100101 100011 011000 010110 1100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
000110	G
100001	h
100101	l
011011	b
110111	3
001001	J
100101	l
011101	d
000110	G
100101	l
100011	j
011000	Y
010110	W
1100	w

When combined, these characters form the encoded string: "dGhlb3JldGljYWw="
