Encrypt and Decrypt Text Files on AIX using OpenSSL

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
#
