[REBOL] Re: REBOL encryption?

sha1 is considered more secure than MD5
checksum/method "your-string" 'sha1
The number of possible sha1 digests is quite large, (can't remember exactly at this moment)
so you should have very little chance of convergence to the same digest from two different
Do you think you will have billions and billions of users? Unless so, either method
shoud be fine for practical purposes. After all, you are not storing state secrets ;)
Remember no method is absolutely secure.
You're biggest problem will be sufficiently large and random passwords, not convergence
of "encrypted" (digested) passwords. Most people's self-choosen "passwords" are way to
short, and way to non-random.
I've got a password generating script if you want a copy, based on a dictionary of 8K
words. It's for /Core right now, but it is on my list to translate to View.
Do a search on the internet for "diceware" for more info.
