How do I extract the hashes from a file encrypted with PBKDF2-HMAC-SHA-1?
#1
Hello. I can't seem to extract the needed hash code from a file encrypted with PBKDF2-HMAC-SHA-1 that is needed for Hashcat. Does anyone have any suggestions? Much appreciated.

there is no generic solution, especially for encrypted files.

Thank you for replying! If there is no generic solution for unique encrypted files, is there a chance it is impossible to write a program that can extract this piece of information? I know what parameters were used for the PBKDF2 password derivation (iterations, SALT, bytes).  Thanks again.

Checking the correct password usually involves (trying) decrypting (part of) the file. Which means you need to know the encryption algorithm and some part of the encrypted data. You are going to need this algorithm specifically implemented in hashcat then.

Much appreciated! Smile
