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
t	01110100
a	01100001
l	01101100
k	01101011

Step 2: Group Bits into 6-bit Chunks

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

011101 000110 000101 101100 011010 11

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011101	d
000110	G
000101	F
101100	s
011010	a
11	w

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