The Question is:
How can I recover a System Password Lost ?
The Answer is :
The OpenVMS password hashing mechanism is deliberately
a non-reversible hashing function (as differentiated from
a reversible scheme based on encryption), and there is no
mechanism available -- short of a brute-force security
attack on the hashed password value, of course -- to
retrieve a user's password based on the hashed password
value.
OpenVMS first hashes the text password into a quadword
value, then compares this value against the saved value
that was hashed from the original password -- the text
value of the password is not maintained nor stored.
Assuming you wish to reset the password for the SYSTEM
or other username, either use the AUTHORIZE utility to
reset the password (from another privileged username),
or use the directions for breaking into the OpenVMS
system that are included in the OpenVMS FAQ and in the
OpenVMS documentation.
