I propose you my decrypter for PESpin 1.0 (author : cyberbob). It just decrypt files packed with the last version of PESpin (not for 0.7 and previous).
I want to thank cyberbob for coding such crypter (it is a very interesting one) and Kaine (my friend) for friendly help. Thanks to DAEMON and R!sc for there sources about the decrypter for tELock 0.51 (which inspire me) and Gbillou for his interest about this small project
