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
k	01101011
a	01100001
t	01110100
r	01110010
i	01101001
n	01101110
a	01100001

Step 2: Group Bits into 6-bit Chunks

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

011010 110110 000101 110100 011100 100110 100101 101110 011000 01

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011010	a
110110	2
000101	F
110100	0
011100	c
100110	m
100101	l
101110	u
011000	Y
01	Q

When combined, these characters form the encoded string: "a2F0cmluYQ=="
