To add a user ’psk_identity’ in keys.psk for use with GnuTLS run:

  $ ./psktool -u psk_identity -p keys.psk
  Generating a random key for user 'psk_identity'
  Key stored to keys.psk
  $ cat keys.psk
  psk_identity:88f3824b3e5659f52d00e959bacab954b6540344
  $

This command will create keys.psk if it does not exist and will add user ’psk_identity’.

One of the following exit values will be returned:

Successful program execution.

The operation failed or the command syntax was not valid.
