About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: One '=' character is added when the input length modulo 3 equals 2. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
e	01100101
s	01110011
s	01110011
e	01100101
n	01101110
t	01110100
i	01101001
a	01100001
l	01101100
l	01101100
y	01111001

Step 2: Group Bits into 6-bit Chunks

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

011001 010111 001101 110011 011001 010110 111001 110100 011010 010110 000101 101100 011011 000111 1001

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011001	Z
010111	X
001101	N
110011	z
011001	Z
010110	W
111001	5
110100	0
011010	a
010110	W
000101	F
101100	s
011011	b
000111	H
1001	k

When combined, these characters form the encoded string: "ZXNzZW50aWFsbHk="
