removing a password |

Jerry Blumenthal | Once a table is password protected, how difficult is it to change the
pwd or to eliminate it? And is this different with different versions of DBIsam? (I'm still working with v2, altho I have v3 as well) Jerry |

"R. Tipton" | I use V4 but if I remember correctly v3 was the same.
Start Dbsys click on alter table under Utilities Enter the name of table to password protect. Click on encrypted then enter the password in the box. To remove the password is the same, except you need to know the password. If you forget the password you will need to use an Hex editor to alter the tables header. If that fails stand outside a junior school and ask a kid Rita "Jerry Blumenthal" <jerry@blumenthalsoftware.com> wrote in message news:825E32DA-F343-4448-A298-9C0385969D95@news.elevatesoft.com... > Once a table is password protected, how difficult is it to change the pwd > or to eliminate it? > > And is this different with different versions of DBIsam?

If that fails stand outside > a junior school and ask a kid A-ah. In V3, the table was "encrypted" by a simple XOR algorithm. With the source code of DBISAM, it's very easy to write a password cracker. V4 is heavy metal - Blowfish. No way to crack it unless you have some good friends in the NSA. You can use other encryption algorithms, eg. IDEA, in V3 and V4 - and then you are really lost in space and time. Ralf |

"R. Tipton" | Yes Ralf Jerry is using V3 by the same I meant the
Dbsys method off setting the password and unsetting the password. I did not imply V4 was anyway easy and as yet I havent got access to a V4 table that was protected. So Jerry if its V4 you want stand outside NASA Rita "Ralf Mimoun" <nospam@rad-on.de> wrote in message news:CB9CE3FD-75B9-4180-80DA-9CF6663A9C61@news.elevatesoft.com... > R.
