Hi John, Please let me know the evolutions of your research. IMHO you may use Truecrypt (www.truecrypt.org), to study many algorithms and hashes. Regards, -- Rodrigo Ramos 81 87273524 81 34631593 www.triforsec.com.br www.defenselayer.com On Thu, 2006-05-11 at 10:20 -0700, John Madden wrote:
Hi, While doing a pen-test I came across a database with encrypted fields and I was curious to try and see what I would do with it. Is it possible to determine the encryption used by "looking" at the encrypted results or lenght ? I know that with Base64 it's pretty easy because of the "==" at the end. I would like to learn more about the subject and considering the amount of documentation out there, I would like your comments on what you have used and found usefull. Also if there are any tools besides openssl that you found usefull to try all the cipher, consecutively with a passphrase/keyword against a file/string Thank you for your time. __________________________________________________ Do You Yahoo!?
