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
a	01100001
r	01110010
l	01101100
i	01101001
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011000 110110 100001 100001 011100 100110 110001 101001 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
100001	h
100001	h
011100	c
100110	m
110001	x
101001	p
011001	Z
01	Q

When combined, these characters form the encoded string: "Y2hhcmxpZQ=="
