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
c	01100011
o	01101111
r	01110010
n	01101110
e	01100101
r	01110010
s	01110011
t	01110100
o	01101111
n	01101110
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011000 110110 111101 110010 011011 100110 010101 110010 011100 110111 010001 101111 011011 100110 0101

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
110110	2
111101	9
110010	y
011011	b
100110	m
010101	V
110010	y
011100	c
110111	3
010001	R
101111	v
011011	b
100110	m
0101	U

When combined, these characters form the encoded string: "Y29ybmVyc3RvbmU="
