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
w	01110111
e	01100101
l	01101100
c	01100011
o	01101111
m	01101101
e	01100101

Step 2: Group Bits into 6-bit Chunks

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

011101 110110 010101 101100 011000 110110 111101 101101 011001 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
110110	2
010101	V
101100	s
011000	Y
110110	2
111101	9
101101	t
011001	Z
01	Q

When combined, these characters form the encoded string: "d2VsY29tZQ=="
