entrop is a password generator (command line tool), that converts a sequence of words with some separator into a password in some charset, using some good algorithms:

• https://en.wikipedia.org/wiki/PBKDF2 ("-a pbs5" or "-a pbs2")
• https://en.wikipedia.org/wiki/Argon2 ("-a ar")
• and some others (see alg.go)

Usage of entrop:

  -a string
        algorithm with optional params: e.g. ar:3:32768 or rh:62500 (default "pbs5")
  -c string
        charset name or spec, see charsets.go (default "alnum")
  -d uint
        alg settings ('defaults') version
  -i    inline mode, i.e. no hidden inputs
  -jcw
        join words using counting mapper
  -l uint
        password length (default 25)
  -nq
        no quality check/retry, same as -q 0
  -q uint
        required num. of character categories for passwd. quality (default 3)
  -s string
        separator (default " ")
  -v    verbose mode
  -version
        print version

In inline mode (-i), separator can be specified with -s option, and words must be specified after flags:

entrop -i -l 15 -s "+++" hello world 12345
# separator=+++; words=hello,world,12345

In a default non-inline mode, separator and words will be asked in hidden inputs (as in read -s). Inline mode is not recommended, it is insecure. Use inline mode only if you can disable commands history in your shell.

GUI

entrop is also available for usage online (for that puprose it was compiled to wasm):
