    In other words, when my Internet service provider will check that I am who I claim to be, will they succeed with either encoded methods?

    Any comment is welcome.
    Hi
    Maybe this will help?

    Your ISP doesn't nothing except store/protect 'your' hash as long as what you send matches the hash stored, all is good.... the hash can't be decoded, that's the point.

    A mime type as seen can be decoded, hence not suitable...

    Thank you for the link.

    As my question is about a login sequence (mailx command) to a smtp server, my ISP must be able to verify that the user { "dXNlcm5hbWU=" ( perl -MMIME ) or "FMSwa4JOxZMjk2JRf1OLKQ" ( perl -MDigest ) } and the password correspond to me in their database ?
    So how could he accepts my connection without knowing who is connecting ?
    Thanks for helping. JCD

    Thank you for the link.

    As my question is about a login sequence (mailx command) to a smtp
    server, my ISP must be able to verify that the user { "dXNlcm5hbWU=" (
    perl -MMIME ) or "FMSwa4JOxZMjk2JRf1OLKQ" ( perl -MDigest ) } and the
    password correspond to me in their database ?

    Hi
    As long as the decoded username matches the hashes they store (however
    the ISP does it [LDAP?]), then it will let you (or anyone who knows the
    username/password) in...

    Have a look at the shadow and passwd man pages (eg man 5 shadow) to see
    how it's done on your local machine.
