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
v	01110110
i	01101001
e	01100101
t	01110100
n	01101110
a	01100001
m	01101101
e	01100101
s	01110011
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011101 100110 100101 100101 011101 000110 111001 100001 011011 010110 010101 110011 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
100110	m
100101	l
100101	l
011101	d
000110	G
111001	5
100001	h
011011	b
010110	W
010101	V
110011	z
011001	Z
01	Q

When combined, these characters form the encoded string: "dmlldG5hbWVzZQ=="
