Encryption

[jackyyll]

Well, i've seen many encryption UDF's/programs/scripts on here, but which one is best? Which one is overall the best encryption method yet? Just wondering, no plans on using it yet..

"Best" depends on what you want it to do, doesn't it? Maybe it would be better to ask:

1. Which is fastest at encrypt/decrypt a file (and specify the size of the file or if it's a continuous stream)?

2. Which has the strongest encryption?

3. Which uses the least CPU cycles? The least memory?

4. Which adds the least overhead bytes to the encrypted data?

5. Which is compatible with certain hardware, apps, network interfaces, etc.?

6. Which has error correction, and how many bad bits per byte/message?

7. Which compiles into the smallest executable?

8. Which was written by the best looking programmer?

9. Including compression?

10. Will it need to be run only in Win32? Also DOS, Win16, OSX, Unix, Linux, unleaded, diesel?

Some of these things won't matter to you, some will be critical. Having collected all that information you can apply it to your particular application to find "Best".

All seriousness aside, though, if you specify the application you have in mind, you'll get much more intelligent answer than this one!

Well im thinking of basically best as in fastest and strongest encryption

What are you trying to Encrypt (.au3, .txt, .log, .dat, .bat, etc...)?

[jackyyll]

Most likely i would be encrypting various strings.

Valuator, is the included encryption any good?

The included _StringEncrypt() is good, and you can mod it to suit your needs.

Edit:

I should say... It isn't the fastest thing in the world however.

Yea, how slow is it?

Depends on how many levels you use... You're best to answer that question, I mean run it on what you want, then decode it, and test the speed.
