Encoding Process: undefined to dW5kZWZpbmVk

Step 1: Map ASCII Characters to Binary

ASCII CharacterBinary Value
u01110101
n01101110
d01100100
e01100101
f01100110
i01101001
n01101110
e01100101
d01100100

Step 2: Group Bits into 6-bit Chunks

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

011101 010110 111001 100100 011001 010110 011001 101001 011011 100110 010101 100100

Step 3: Convert Binary to Base64

Binary ValueBase64 Character
011101d
010110W
1110015
100100k
011001Z
010110W
011001Z
101001p
011011b
100110m
010101V
100100k

When combined, these characters form the encoded string: "dW5kZWZpbmVk"
