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
o	01101111
e	01100101
c	01100011
d	01100100

Step 2: Group Bits into 6-bit Chunks

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

011011 110110 010101 100011 011001 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011011	b
110110	2
010101	V
100011	j
011001	Z
00	A

When combined, these characters form the encoded string: "b2VjZA=="
