From: Antonio Ospite Date: Tue, 9 Apr 2013 12:01:21 +0000 (+0200) Subject: Use exrex.count() to know how many strings the regex generates X-Git-Url: https://git.ao2.it/crackpop.git/commitdiff_plain/38d8e69e7cc789683e68005846a747aa6e23f1cc?hp=2258ef0e945e565f4d5fef0fa9ac8c6d47444293 Use exrex.count() to know how many strings the regex generates exrex uses generators, so this saves memory as we don't have to store the whole list of results anymore. While at it refactor things a little bit so to pass the number of elements to the crackpop() function too. --- diff --git a/crackpop.py b/crackpop.py index b032da6..8d9a45b 100755 --- a/crackpop.py +++ b/crackpop.py @@ -26,26 +26,31 @@ __version = "0.1" __author_info = "Antonio Ospite" +# returns a tuple: (num_passwords, passwords) +# where passwords is an iterable type def generate_passwords(password_pattern, dry_run=False): - passwords = list(exrex.generate(password_pattern)) + num_passwords = exrex.count(password_pattern) + passwords = exrex.generate(password_pattern) if dry_run: - print "Generated %d passwords." % len(passwords) + print "Generated %d passwords." % num_passwords for p in passwords: print p - return [] + return (0, iter([])) - return passwords + return (num_passwords, passwords) +# the passwords parameter is a tuple: (n, L) +# where L is an iterable type and n is the number of elements in L def crackpop(host, port, ssl, user, passwords): if ssl: pop3_connect = poplib.POP3_SSL else: pop3_connect = poplib.POP3 - print "Testing %d passwords." % len(passwords) - for p in passwords: + print "Testing %d passwords." % passwords[0] + for p in passwords[1]: # TODO maybe the same connection can be reused for more than one try, # but some logic needs to be added to detect the maximum allowed # authentication attempts or a disconnection from the server.
