zip with password 1

[alan147]

Hello

I need to ftp some files off my machine to a remote site. My company wants to put a password on the file to make it more secure. Is there a UNIX application that will allow me to zip up the files and put a password on the zipped file?

Thanks

Alan

Hi Alan,

You could produce a tar archive.

Then use gzip to compress it.

Then either

1. ftp it to your PC for secure emailing via some form of encryption (PGP etc).

or

2. You could encrypt the GZIP'd TAR archive using openssh (if you have it installed).

You can encrypt/decrypt a file using OpenSSH with something like the following commands.

# Encrypt orig_file to enc_file.
openssl bf -salt -in ./orig_file >./enc_file

# Decrypt enc_file back to orig_file.
openssl bf -d -in ./enc_file >./orig_file2

Both openssl commands in the above examples use bf (for BlowFish) and will request a password.

The receivers of the file will have to go through the reverse process (and will require the password) to extract your files.

Best of Luck ;-)
