Notes on implementing 
-------------------------------------------------------------------------------#
Perl Encryption

Key document appears to be  Crypt::CBC
whcih allows to you generate not only openssl compatible encrypted files
but also 'RandomIV' headered encrypted files.

However there was a compatiblity issue at version 2.17 for 'RandomIV'
encryptions.

See "encrypt.pl" where I have implented a perl encryption solution.

Crypt::CBC

A simplified wrapper around the various Crypt librayr methods with
compatibility to the openssl.

See Example code in man page AND in shared documentation area
   /usr/share/doc/perl-Crypt-CBC-2.29/eg/

However the module does not provide PBKDF v2 capability!
Though you can pass it a password so it generates a key, salt and iv as
appropriate.

See "encrypt.c" and "encrypt.pl" for local examples
Perl version is at...

PBKDF v2 from perl.

No proper solution at yet.

Currently I access the PBKDF2 library function from OpenSSL via a
trival C program to pipeline passwords into encryption keys and IV
