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
c	01100011
h	01101000
e	01100101
c	01100011
k	01101011
b	01100010
o	01101111
x	01111000
e	01100101
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011000 110110 100001 100101 011000 110110 101101 100010 011011 110111 100001 100101 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
100001	h
100101	l
011000	Y
110110	2
101101	t
100010	i
011011	b
110111	3
100001	h
100101	l
011100	c
11	w

When combined, these characters form the encoded string: "Y2hlY2tib3hlcw=="
