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
k	01101011
n	01101110
o	01101111
w	01110111
l	01101100
e	01100101
d	01100100
g	01100111
e	01100101
a	01100001
b	01100010
l	01101100
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011010 110110 111001 101111 011101 110110 110001 100101 011001 000110 011101 100101 011000 010110 001001 101100 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
110110	2
111001	5
101111	v
011101	d
110110	2
110001	x
100101	l
011001	Z
000110	G
011101	d
100101	l
011000	Y
010110	W
001001	J
101100	s
011001	Z
01	Q

When combined, these characters form the encoded string: "a25vd2xlZGdlYWJsZQ=="
