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
p	01110000
c	01100011
o	01101111
s	01110011

Step 2: Group Bits into 6-bit Chunks

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

011100 000110 001101 101111 011100 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011100	c
000110	G
001101	N
101111	v
011100	c
11	w

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