Stanza names for pwmod.sha512

The stanzas that pwmod.sha512 add to /etc/security/pwdalg.cfg are not descriptive of password algorithm that is being used as they are just 5 and 6.

    Hi, the stanzas created for the Linux compatible hash are as follows:

    6:
    lpa_module = /usr/lib/security/lsha
    lpa_options = algorithm=sha512,prefix_dollar

    5:
    lpa_module = /usr/lib/security/lsha
    lpa_options = algorithm=sha256,prefix_dollar

    Note the stanza name "5" and "6" are consistent with choice of linux.
    Since the stanza name is included as a part of password hash,
    to be compatible with Linux, we must use the same name (as used in Linux).

    if you don't care about the compatibility with Linux,
    only want to elect the Drepper hash,
    you may choose a different stanza name, e.g.,

    lsha512:
    lpa_module = /usr/lib/security/lsha
    lpa_options = algorithm=sha512,prefix_dollar

    Then you can use:

    chsec -f /etc/security/login.cfg -s usw -a pwd_algorithm=lsha512
