how to create password protected encripted file in Unix

[rajesh...@gmail.com]

HI,

I am trying to compress files in unix and protect it with a password.
In windows its easy with winzip. Is there any easy way to encrypt files
with password in unix??

Thanks in advance,
Raj

According to <rajesh...@gmail.com>:
:HI,

:

look for source code for info-zip. It works on winzip files.

There's 'crypt', easy to use, but attacks on the scheme used there are known.
For stronger protection there's 'pgp' ('pgp -c plainfile' and 'pgp -d cfile').

The traditional tool, crypt(1), uses DES, which isn't considered
secure anymore. Look for GnuPG for strong cryptography (both,
symmetric and asymmetric ciphers).
