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
m	01101101
a	01100001
t	01110100
t	01110100
r	01110010
e	01100101
s	01110011
s	01110011
e	01100101
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011011 010110 000101 110100 011101 000111 001001 100101 011100 110111 001101 100101 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011011	b
010110	W
000101	F
110100	0
011101	d
000111	H
001001	J
100101	l
011100	c
110111	3
001101	N
100101	l
011100	c
11	w

When combined, these characters form the encoded string: "bWF0dHJlc3Nlcw=="
