Encoding Process: binary to YmluYXJ5

Step 1: Map ASCII Characters to Binary

ASCII CharacterBinary Value
b01100010
i01101001
n01101110
a01100001
r01110010
y01111001

Step 2: Group Bits into 6-bit Chunks

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

011000 100110 100101 101110 011000 010111 001001 111001

Step 3: Convert Binary to Base64

Binary ValueBase64 Character
011000Y
100110m
100101l
101110u
011000Y
010111X
001001J
1110015

When combined, these characters form the encoded string: "YmluYXJ5"
