UNIX Compress utility with password security

[Kusuma Sashidhar]

Hi,

Is there any utility (open source) that I can user to create a tar/zip file wherein i can store username and password to read or extract the tar/zip file.

Please help.

Regards,
Kusuma

Hi Kusuma,

There is a command called 'crypt' that you can use to crypt files. For ex.,

crypt in_file > outfile
Enter Key:
rm in_file

Now out_file is encrypted and you have to decrypt using the key you typed in above. To do it run the same command

crypt < outfile > orig.file
Enter Key:

So, just create regular tar/zip archive and then crypt it using the above method.

Thank you so much. It worked. But a small change when i tried on hp-unix. The below command worked.

crypt key dest
