Decrypting SHA1 passwords at once - xeriuk - Dec 18, 2018

Hi,

I’ve got a dump of a sql database in a plain text file. The passwords are encrypted in SHA1.

The file is formatted this way:

id username email password
1 test123 [email protected] jaj8ytqbfo7164hah

Just an example ofcourse. But is there a easy way to remove all the data except the password hashes, and after that dehash all of the records with a program/tool? I tried decrypting some pws myself using an online decrypter, which seems to work. But this will be a very slow process to do manually.

Any help is appreciated

I mean you could also dehash with hashcat decently quick if you've got good wordlists and what not. Do you know any programming languages? I made some functions in my winform account checker app that extracts hashes from a combo dump like yours then will replace found hashes in the original dumped file. I could send the code snippet's if you know c#

Sadly I don't have experience in C#, only web based programming languages. Anyway, thanks for the info :)
