Encoding Process: aud to YXVk

Step 1: Map ASCII Characters to Binary

ASCII CharacterBinary Value
a01100001
u01110101
d01100100

Step 2: Group Bits into 6-bit Chunks

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

011000 010111 010101 100100

Step 3: Convert Binary to Base64

Binary ValueBase64 Character
011000Y
010111X
010101V
