x = hashlib.md5(str(x).encode()).hexdigest()
enc.append(int(x, 16))

Solution
Since the range is limited to ascii characters, we can map each individual hashed character to the encrpyted test and decode it
m=[]
for i in range(256):
m.append(int(hashlib.md5(str(i).encode()).hexdigest(),16))
for i in c:
if i in m:
print(chr(m.index(i)),end="")
