NAME
   session-token - command-line script for generating session tokens

USAGE
       $ session-token
       ATXOpAxCu57sVZvoBiWgHg

       $ session-token --entropy 256
       hk0No9bjuknBxmpIujW3bZvnFmryTvEbTPNitd8L9kC

       $ session-token --length 5 --alphabet ACGT --num 3
       GAATT
       ACCAT
       AATTG

       ## If you don't know how many tokens you need at the start of the pipeline...
       $ session-token --infinity | ... | head

DESCRIPTION
   This module came about because I found myself frequently running the
   following command:

       $ perl -MSession::Token -E 'say Session::Token->new->get'
       YwXYXGLMMnudk33MbClseQ

   Before I wrote Session::Token I used to run the following command:

       $ openssl rand -base64 16
       fjxhL/LmZEUQ+NCldQbHgA==

   They both perform essentially the same task however "session-token" has
   various advantages:

   It is more flexible regarding the alphabet used since it supports any
   alphabet that Session::Token does via the "--alphabet" switch. Its
   default alphabet is the (IMO) nice base-62 versus "openssl rand"'s
   base-64.

   It can efficiently generate a large number of random tokens with the
   "--num" switch. Calling "openssl rand" for each token would fork a lot
   of processes and open and read from "/dev/urandom" in each one.

   If cross-platform determinism is required, the "--seed" or "--null-seed"
   switches are available and they don't require seed files or anything.
   Note that you should only use these switches for benchmarks or
   simulations and never for applications requiring secure randomness since
   the generated sequence of tokens will be the same for each run.

   "openssl rand" does some weirdness with reading from/writing to the
   "~/.rnd" file in your home directory as a potential entropy
   source/store. "session-token" will always fail noisily if it can't read
   from "/dev/urandom".

   Finally, "session-token" is easier to remember and type don't you think?
