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
n	01101110
s	01110011
i	01101001
o	01101111
n	01101110

Step 2: Group Bits into 6-bit Chunks

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

011011 010110 000101 101110 011100 110110 100101 101111 011011 10

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011011	b
010110	W
000101	F
101110	u
011100	c
110110	2
100101	l
101111	v
011011	b
10	g

When combined, these characters form the encoded string: "bWFuc2lvbg=="
