Announcing HashPass

HashPass allows a user to input a password or any text and generate a hash from it.

Generally a secure password is hard to remember so users tend to opt for easy to remember passwords. These passwords are also easy to crack. This app aims to address that by allowing the user to use hashes in place of their passwords on various sites.

Example: a user may have a password such as “computer” (a bad one) that would be easily cracked in a dictionary attack.

Where as the md5 hash generated from computer is
df53ca268240ca76670c8566ee54568a which is not easy to guess or dictionary attack.

There are currently four algorithms available in the app. MD5 , SHA1 , SHA256 & SHA512.

This allows the user to use the same password for four different sites and a different hash for each.

For your banking or email you could use the SHA512 hash of your chosen password . In the computer example the hash is

922d076069b1df893fc010b7a6d2aa55c7c4c5d194f163394a4c864de5754131c17bfa94ac166

The hashes are automatically copied to the clipboard for convenience. This allows you to paste it into an app such as facebook or an email app.

If a database is compromised which is insecurely storing the passwords and your passwords (your generated hash) was obtained . The other three sites (with different hashing algorithms) would be safe.

Using hashes as passwords also makes an attack more computationally expensive as each string (sequence of characters) has to be hashed first before submitting it as the password. Also that factor is multiplied by 4 as the attacker does not know which algorithm you may have chosen.

You could also paste the output of the initial hash as the input with different functions for more options. Just remember the algorithms and the order you chose if you do.

I have also made an open sourced command line desktop version which is written in python and can be downloaded from https://minus.com/mBDxG4GLu/

Announcing Bodha Converter

Bodha Converter default screen

Bodha Converter is an android app I made a while ago which I only got around to publishing recently. It allows users to convert between Binary, Octal, Decimal, Hex and Ascii with a zen like approach.

It supports general (Binary , Octal , Decimal and Hex ) conversions up to 2^63-1 in their respective formats. It also supports Ascii characters in the range of NUL to DEL (0 – 127)

A convenient table is also included for quick lookups also in the range of 0 – 127

This app collects no personal data. The internet permission is only required to serve advertisements. It can be obtained from the google play marketplaceĀ 

Hope you find it useful.
