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
g	01100111
e	01100101
o	01101111
p	01110000
h	01101000
y	01111001
s	01110011
i	01101001
c	01100011
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011001 110110 010101 101111 011100 000110 100001 111001 011100 110110 100101 100011 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
110110	2
010101	V
101111	v
011100	c
000110	G
100001	h
111001	5
011100	c
110110	2
100101	l
100011	j
011100	c
11	w

When combined, these characters form the encoded string: "Z2VvcGh5c2ljcw=="
