R – FastMM, stack trace memory for leaks in dynamicly loaded DLL, compiled with runtime packages

You do it by assigning to the Boolean variable System.ReportMemoryLeaksOnShutdown.

This will allow you to control the single most important setting, the reporting of memory leaks. If you want more fine grained control of the FastMM settings then include FastMM in your project just as you did in Delphi 7.

Try something like this (altho i do have PyCrypto installed)

from Crypto.Cipher import AES
import base64

AES.key_size=128
iv="your iv"
key="your key"
crypt_object=AES.new(key=key,mode=AES.MODE_CBC,IV=iv)

decoded=base64.b64decode(plain) # your ecrypted and encoded text goes here
decrypted=crypt_object.decrypt(decoded)

This will bring the decoded text but it will be padded with bytes for it to be a size multiple of 16.

You should probably decide on a proper padding scheme and remove it afterwards accordingly
