File password protection/encryption - AIX

rdudejr · #1 (**permalink**) 07-05-2006

Can it be done? Ive read in a few places that the crypt program no longer exists on AIX...if its do-able please tell me how.

AIX dropping crypt surprised me too. Using standard AIX software, no, I do not believe there is a way to password encrypt a file. However, you can compile/install OpenSSL available from http://www.openssl.org

There are oodles of encryption algorithms and encrypting a file is quite simple.

Code:

# openssl enc -aes-256-cbc -in file -out file.enc
enter aes-256-cbc encryption password: password
Verifying - enter aes-256-cbc encryption password: password
#

To decrypt, simply swap your -in and -out file parameters and add a -d to the command line:

Code:

# openssl enc -d -aes-256-cbc -in file.enc -out file
enter aes-256-cbc encryption password: password

You don't even have to compile OpenSSL. The first part of this rsync tutorial (http://www.pseriestech.org/forum/tut...-files-89.html) explains where to get and how to install OpenSSL and OpenSSH to make rsync more secure.
