Encoding Process: surely to c3VyZWx5

Step 1: Map ASCII Characters to Binary

ASCII CharacterBinary Value
s01110011
u01110101
r01110010
e01100101
l01101100
y01111001

Step 2: Group Bits into 6-bit Chunks

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

011100 110111 010101 110010 011001 010110 110001 111001

Step 3: Convert Binary to Base64

Binary ValueBase64 Character
011100c
1101113
010101V
110010y
011001Z
010110W
110001x
1110015

When combined, these characters form the encoded string: "c3VyZWx5"
