recupero password

[antoniod82]

salve,

nn ricordo la password per il file al seguente link:

http://www.diee.unica.it/powersystem...sibili-pdf.exe

nn si tratta di nulla di scottante, è solo del materiale per l'università.

qualcuno sarebbe così gentile da aiutarmi suggerendomi un programma per il recupero?

grazie

Non è possibile, senza password il file è irremediabilmente perso, utilizza un algoritmo di criptaggio non meglio specificato ( almeno io non l'ho trovato )

Dalle FAQ delo sito:

I lost my passphrase. Can you help me?
The basic rule is: If you lose or forget your passphrase or key-file, your documents are lost. There is no back-door into AxCrypt.

The only way to recover a lost passphrase is to try all likely combinations. If you have used a key-file, and lost that, there is nothing to do at all - the number of combinations is simply too large. That is why you must print a paper backup copy if you use key-files.

All that being said, there is a special case where I could possibly help you. If you think you know your passphrase, but not quite, or if it's less than 5 characters long - then I can write and adapt a special program that will try many combinations automatically. This is called a brute force attack.

AxCrypt is specifically engineered to counter brute force attacks, and does it rather well, so this will only work when the number of combinations to try is very small, let's say less than a million.

If you think you may be in a position where you can narrow down the possible combinations enough for me, then there is a slight chance to recover the passphrase.

A brute force attack requires custom programming and many hours, days and possibly weeks and months of computer time, thus I will only do this when compensated and when I feel that that it might be possible. But it's always done on a no cure - no pay basis, this means that if I can't find the passphrase, there's no fee. The fee depends on the amount of programming necessary, typically it'll vary between USD/EUR 50 to 250.

(I've attempted this four times so far, and succeeded once. The password was a word with four letters, where the first letter turned out to be a 'y' instead of 'm' as the user apparently had mistyped. That's the kind of situation where a brute force attack may be successful.)
