Encoding Process: harold to aGFyb2xk

Step 1: Map ASCII Characters to Binary

ASCII CharacterBinary Value
h01101000
a01100001
r01110010
o01101111
l01101100
d01100100

Step 2: Group Bits into 6-bit Chunks

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

011010 000110 000101 110010 011011 110110 110001 100100

Step 3: Convert Binary to Base64

Binary ValueBase64 Character
011010a
000110G
000101F
110010y
011011b
1101102
110001x
100100k

When combined, these characters form the encoded string: "aGFyb2xk"
