Hasher

Hasher is a universal application to calculate hash digests from various input formats or files. It can also be used as a general-purpose bytes encoding converter or a password generator. It's basically a frontend to Python's hashlib.

Note

To make Hasher work on all SailfishOS versions, I had to re-package all of its Python dependencies. If you have trouble installing, try reinstalling all of them: attrs, xdgspec, base91 and pwdhash.

Applications

You could use Hasher to:

• check various hashsums of text or files
• determine whether a downloaded file was corrupted by verifying its hashsum 
• convert text to its binary, octal, hexadecimal, Base64 or Base91 representation
• convert between the abovementioned formats
• generate strong passwords from a master password, for example:
  • Use the CryptoPass password generation scheme
  • Use the PwdHash algorithm
  • Or use PBKDF2_HMAC directly
  • select the PBKDF2_HMAC algorithm
  • enter your masterpassword
  • as salt, use a string like mylogin@service.de
  • choose a high number of iterations
  • choose a desired hash length
  • use the BasE91- or Base64-encoded result as password

Features

• hash algorithms supported by Python's  hashlib
• CryptoPass password generation scheme
• PwdHash password mangling scheme
• files as input
• input text in several encodings (UTF8, binary, octal, decimal, hexadecimal, base64, base91)
• input text can be examined in different encodings to make sure it is interpreted as intended
• digest can be displayed in different encodings
• digest can be copied to the clipboard
• digest is shown on the cover and can be hidden

On the ToDo-List

• using an online service like md5online.org or md5decrypt.net for looking up (”decrypting”) digests
• remembering the UI settings
• interrupting long-runing hashing operations (discussion on GitLab)
• defining ”pipelines” of hash operations (e.g. concatenate these strings, then hash 100 times with sha512, then encode with Base64 and take the first 10 characters) to facilitate a hash-based password mechanism

Known Issues

• Closing Hasher does not interrupt long-running hashing operations (like hashing huge files)
