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
j	01101010
p	01110000
e	01100101
g	01100111

Step 2: Group Bits into 6-bit Chunks

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

011010 100111 000001 100101 011001 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
100111	n
000001	B
100101	l
011001	Z
11	w

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