I have found a module pycrypto which has an AES encryption and decryption function, in commandline everything works fine both encryption and decryption,
but if I want to implement it in my program, it fails =(
def aes(txt): global crypt message="".join(txt) #format the message which has to be encrypted/decrypted to a string c=0 plist="".join(pflist) while len(plist)<15: plist+="a" c+=1 #loop is to be sure the password has at least 16 characters. plist+=str(c) obj=AES.new(plist[:16], AES.MODE_ECB) if crypt == "en": c=0 while len(message)/16 != len(message)//16: message+="a" c+=1 #loop is to be sure the message is a multiple of 16 ciphertext=obj.encrypt(message) else: print message,len(message) ciphertext=obj.decrypt(message) return ciphertext
The encryption system succeeds, but the decryption system fails
if I decrypt it with \xb4\xe0\xa0LH/\xefO\xc9|y7&"Af
the program says it has a length of 31 (which strictly seen is also true),
but if you do the following in command line it will say that the length is 16
I don't know what's wrong... I think it has to do something with the type in which the \xb4\xe0\xa0LH/\xefO\xc9|y7&"Af is passed but I'm not sure...
