Encoding Process: butts to YnV0dHM=

Step 1: Map ASCII Characters to Binary

ASCII CharacterBinary Value
b01100010
u01110101
t01110100
t01110100
s01110011

Step 2: Group Bits into 6-bit Chunks

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

011000 100111 010101 110100 011101 000111 0011

Step 3: Convert Binary to Base64

Binary ValueBase64 Character
011000Y
100111n
010101V
1101000
011101d
000111H
0011M

When combined, these characters form the encoded string: "YnV0dHM="
