This does not guarantee your password is strong, but it's a pretty damn good for most applications. Requires less than 1 year to crack: "Awful.Of course, as hashing and cracking technology increases, the speed we use to calculate this strength will need to be updated. This way, a person can protect their data with a given password for their lifetime. The target is to have a password that will take more than 100 years to crack. The strength of a password is determined by how likely a user will die before the password is brute forced, given current cracking technology. What we mean by "crack"įor the purposes of this calculator, a password is deemed to have been "cracked" after 50% of the search space can exhaustively be searched. This gives us the total number of seconds required to search 50% of the password's search space. Now, given current cracking ability, we can try 100,000,000,000,000 attempts per second, we can divide out the possible combinations (2.4 x 10^28) by 1 x 10^14. Now, we have a 1 in 2 chance of finding the password of we search half of that search space, and so, that reduces the search space to (2.4 x 10^28), which is still enormous. The command spwgen.py -a strong generates a password like: SSWltcnwo0pARJY7. The strength analysis this program performs is a search space calculation, which is compared against current cracking ability. We would like it to mean: "This password is hard to crack", however the reality is that there are a number of ways to crack a password. Password strength is a somewhat nebulous term. This is entirely dependent on whether or not your chipset has a has a TRNG. Thus, if you do not have a good source of randomness on your computer, you will not get good secure numbers. provides access to the most secure source of randomness that your operating system provides". "Cryptographically secure" is a somewhat relative term. Support and Issuesįor support, problems, and issues, file an issue on github Security How secure can it be? The secrets module automatically uses the best source of randomness available on your system, which gives us the bestĬhance and making secure passwords. Want to generate random mac addresses? Can't. because users rarely rtfm, and usually use pwgen_secure generates secure passwords by default. You have to use the -s option to get secure Secure by defaultīy default, pwgen creates passwords easy for a human to memorize. There are a number of reasons we wrote spwgen, but the main reason was: we wanted a password generator that was flexible and which would use the best available sources of entropy. Two lower case characters for the next two characters, followed by: Two upper case characters for the first two characters of the pattern, followed by:Ģ. Random MAC address: spwgen p 'h Print the previous character n times.ġ. Random password for a website, and show the timing spwgen slut 16 Here are examples for you, Captain Impatient. If you do not have Python 3.6, you can download and install it from. ("cryptographically secure" is a relative term. Pwgen_secure requires Python 3.6 above because it uses the secrets module for cryptographically secure random numbers. Quickstart: How do I make passwords? Installation Generate cryptographically secure random passwords with specified character sets, patterns, or lengths. Pwgen_secure - Secure Python random password generator
