How do I encrypt a file?
In a recent answer, I confirmed that sending an encrypted document as an attachment is a pretty reasonable approach to sending information securely in what is otherwise an unsecure medium - email. Even though there are approaches to encrypting email, they're either obscure or complex and not as ubiquitous as we'd like.
I'll look at two approaches to encrypting a single file that can then be sent securely in email that can typically be decrypted by just about anyone.
I'll also take special care to call out what is the weakest link and the thing that is most likely to allow your encryption to be cracked. It may not be what you think.

*** Word o' the Week
Encryption is the process of mathematically processing data using an encryption "key" - such as a password or passphrase - in such a way that the result of the combination is unrecognizable as the original. Encrypted data can be restored to its original form by reprocessing it using the original encryption key (symmetric encryption) or the matching key of a key pair (asymmetric encryption).
Word o' the Week features a computer term or acronym taken from the Ask Leo! Glossary. If there's a word you're not sure of and would like to see defined, click here to let me know.
*** Thoughts and Comments
Yes, there'll be an Ask Leo! newsletter on Christmas day. Fortunately the newsletter is created in various stages ahead of time, ranging from several days to the day before. If my elves and I have our act together, we won't be working Christmas Eve.
But I also realize that, hard as it might be to believe, reading Ask Leo! on Christmas Day might not be at the top of your priority list.
Because of that I want to take this opportunity to wish everyone a very Merry Christmas and/or the best wishes for whatever other holiday you might be celebrating this time of year. (If that's "none", then ... Happy Tuesday!).
All that assumes, of course, that the Mayan Calendar end of the world prediction is wrong.
Have a great holiday, everyone,
