Ask HN: Can you determine encryption pwd with an encrypted and unencrypted file?

- svennek 10y agoThat depends on the encryption method used. If it is any good, then no.
- benologist 10y agoI think it's AES 256 bit, is that good?
- svennek 10y agoYeah, that is state of the art. No chance there...
- brudgers 10y agoIf the password is weak [e.g. "12345", "pa55w0rd", "eatMoreCHKin68", etc.] and the encryption implementation is available, then an educated brute force generation of encrypted files could recover the password. That's the principal behind rainbow tables. Of course the data has to be valuable enough to justify such an attack and the cost of using physical methods [e.g. theft, keylogging, etc.] has to be higher. Good luck.
