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
i	01101001
l	01101100
o	01101111
m	01101101
e	01100101
t	01110100
e	01100101
r	01110010
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011010 110110 100101 101100 011011 110110 110101 100101 011101 000110 010101 110010 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
110110	2
100101	l
101100	s
011011	b
110110	2
110101	1
100101	l
011101	d
000110	G
010101	V
110010	y
011100	c
11	w

When combined, these characters form the encoded string: "a2lsb21ldGVycw=="
