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
p	01110000
e	01100101
r	01110010
c	01100011
e	01100101
n	01101110
t	01110100
a	01100001
g	01100111
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011100 000110 010101 110010 011000 110110 010101 101110 011101 000110 000101 100111 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
000110	G
010101	V
110010	y
011000	Y
110110	2
010101	V
101110	u
011101	d
000110	G
000101	F
100111	n
011001	Z
01	Q

When combined, these characters form the encoded string: "cGVyY2VudGFnZQ=="
