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
b	01100010
b	01100010

Step 2: Group Bits into 6-bit Chunks

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

011101 110110 010101 100010 011000 10

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
110110	2
010101	V
100010	i
011000	Y
10	g

When combined, these characters form the encoded string: "d2ViYg=="
