Encript Text File

Ricardo Bassoi — Thu, 09 May 2002 18:22:52 GMT

Hi All,

I have a txt file < filename.csv > and I want to do:
1- Encript the file
2- Send by FTP to other machine ( This I know )
3- Remove the encript from the file

The solution to encript must be fast and secure.

Tks,

Bassoi

Hi Ricardo,

Take a look at the crypt command for simple encryption/decryption scheme.

man crypt (1) & (3C)

Takes standard input & writes standard output & uses a "password" as a key where password can be as simple as three lower case chars which can be passed to the recipient in a secure fashion or used by yourself after the ftp arrives.

HTH,
Jeff

Use "crypt" command .. for example ..

# crypt < data > data.secret
Enter key:
# ll data.secret
==> transfer data.secret over

To encrypt .. (on the other side)

# crypt < data.secret > data.txt
Enter key:
# ll data.txt
# cat data.txt

The Enter key part allows you to kindda put in a "password" before you encrypt it and de-crypt it.

Ricardo,

Use the crypt command:

To encrypt simply pipe the STDOUT of
the file to "crypt" and redirect it to
a new file name. Enter a passowrd when
prompted with "Enter key".

$ cat foo | crypt > foo.e
Enter key:

To unencrypt simply pipe the STDOUT of
the encrypted file to "crpyt" and
redirect it to a new file name. Enter
a passowrd when prompted with
"Enter key".

$ cat foo.e | crypt > foo.new
Enter key:

Hope this helps !

Thanks,
Shabu
