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
b	01100010
a	01100001
c	01100011
k	01101011
s	01110011
t	01110100
r	01110010
e	01100101
e	01100101
t	01110100

Step 2: Group Bits into 6-bit Chunks

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

011000 100110 000101 100011 011010 110111 001101 110100 011100 100110 010101 100101 011101 00

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011000	Y
100110	m
000101	F
100011	j
011010	a
110111	3
001101	N
110100	0
011100	c
100110	m
010101	V
100101	l
011101	d
00	A

When combined, these characters form the encoded string: "YmFja3N0cmVldA=="
