NAME

 bmkpasswd - bcrypt-enabled mkpasswd

SYNOPSIS

 bmkpasswd [OPTIONS]... [PASSWD]

OPTIONS

 -h, --help

 -b, --benchmark
     Show timers; useful for comparing hash generation times.

 -m, --method <TYPE>
     crypt method.
     Types:
       bcrypt (default; requires Crypt::Eksblowfish)
       sha512 (requires recent libc or Crypt::Passwd::XS)
       sha256 (requires recent libc or Crypt::Passwd::XS)
       md5 (fast, portable, weak)

 -c, --check <HASH>
     Check password against <HASH>.
     Method will be auto-detected.

 -w, --workcost <COST>
     bcrypt-only.
     Specify a work cost factor. Higher is slower.
     Must be a two-digit power of 2.
     Pad with zeros as necessary.

DESCRIPTION

Simple bcrypt-enabled mkpasswd.

While SHA512 isn't a bad choice if you have it, bcrypt has the advantage of including a configurable work cost factor.

A higher work cost factor exponentially increases hashing time, meaning a brute-force attack against stolen hashes can take a very long time.

See App::bmkpasswd for more details.
