Experts,
I am trying to encrypt my filesystem using the AES 256 bit type of encryption. I am using FreeBSD 5.4 and need to encrypt one of the mounted points. Does anybody have any good idea of how to do it?
Is there any documentation about encrypting the disk partition as this method is more... (2 Replies)
My dilemma,
I need to send, deemed confidential, information via e-mail (SMTP). This information is sitting as a file on AIX. Typically I can send this data as a e-mail attachment via what we term a "mail filter" using telnet. I now would like to somehow encrypt the data and send it to a e-mail... (1 Reply)
I am developing a JAVA application that must encrypt its data. On my development machine, I can use a 256 bit key with no problem. A test machine throws an exception complaining about an illegal key length. The test machine is using JRE 1.6u21. Does anyone know where I can get a version of the JRE... (1 Reply)

Hi all,
I'm looking for secure file encryption tools that use MAC address as encryption key. FYI, I'm using Red Hat Enterprise Linux OS.
For example: when A wants to send file to B
A will encrypt the file with B's computer MAC/IP address as an encryption key
This file can only be decrypted... (2 Replies)
Toucan software uses 256bit AES encryption using ccrypt (https://en.wikipedia.org/wiki/Ccrypt)
i want to ask if its secure to use this ccrypt encryption for storing .TXT file with my passwords on cloud storage like Google Drive? (7 Replies)
Various Node-Red crypto modules do not work with PHP, so to send an encrypted message from a PHP script (in this case from a Ubuntu server) to Node-RED we need our own code.
After a few hours of searching, testing various libs, more testing and debugging, I got this PHP to Node-RED code... (0 Replies)

DESCRIPTION
The bswap16(), bswap32(), and bswap64() functions return a byte order swapped integer. On big endian systems, the number is converted to
little endian byte order. On little endian systems, the number is converted to big endian byte order.
The be16toh(), be32toh(), and be64toh() functions return a big endian byte ordered integer converted to the system's native byte order. The
return value will be the same as the argument on big endian systems.
The le16toh(), le32toh(), and le64toh() functions return a little endian byte ordered integer converted to the system's native byte order.
The return value will be the same as the argument on little endian systems.
The htobe16(), htobe32(), and htobe64() functions return a integer in the system's native byte order converted to big endian byte order. The
return value will be the same as the argument on big endian systems.
The htole16(), htole32(), and htole64() functions return a integer in the system's native byte order converted to little endian byte order.
The return value will be the same as the argument on little endian systems.
The be16enc(), be16dec(), be32enc(), be32dec(), be64enc(), be64dec(), le16enc(), le16dec(), le32enc(), le32dec(), le64enc(), and le64dec()
functions encode and decode integers to/from byte strings on any alignment in big/little endian format.

The hto*() and toh*() functions first appeared in FreeBSD 5.0, and were originally developed by the NetBSD project.
The encode/decode functions first appeared in FreeBSD 5.1.
