For some, it may mean ease of use.
For others, it means that decryption can occur on Sun, Linux, Macintosh and other machines.
A recent passing of a relative found they had encrypted the hard drive which held not only financial records, but scans of family documents, pictures and more. My advice for that relative is to get a forensic expert on it and not to diddle with it since they think there are some accounts "out there" to be found.
Anyhow, fill in the definition since there are dozens out there.
Please let me know if anyone knows of a good File encryption program for CD's and Files?
