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
a	01100001
l	01101100
t	01110100
o	01101111
g	01100111
e	01100101
t	01110100
h	01101000
e	01100101
r	01110010

Step 2: Group Bits into 6-bit Chunks

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

011000 010110 110001 110100 011011 110110 011101 100101 011101 000110 100001 100101 011100 10

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
010110	W
110001	x
110100	0
011011	b
110110	2
011101	d
100101	l
011101	d
000110	G
100001	h
100101	l
011100	c
10	g

When combined, these characters form the encoded string: "YWx0b2dldGhlcg=="
