..Damm Me.. It works ! Man - T-H-A-N-K-S ! I thought I've lost for that data
forever .. and it's not funny option .. Thanks again. (PS: cryptoloop wasn't
started - I don't know what I've been thinking about ..)
.. aha.. but I find another method to decrypt that encrypted by AES256
data, ..using aespipe ...and it works fine, but it's good to know that I can
count on loop-aes too.
Great Thing happen !
