Excelent post! I wish I could +10 it :P. I must admit I didn't totally understand all the explanation (with a litle of shame). I'm now going to re-read it. Thank you so much!

comment Encrypting algorithm
yes, you are correct, that really answer the question I've made. I just asume it woudn't be necesary to say that I don't want the same result repeating for different texts.

I think I was looking for hashing algorithms, thanks!. Why would a "decryptable" algorithm be more secure than a non "decryptable"?

In asymmetric algorithms the sender and reciever don't have to share a key, (beside the public one)?? wow.. Still, I'm looking for something wich can't be decrypted.

I've some information that I don't want to have again, I'll just use it to compare it. (i.e. password). If I flip each bit randomly I can't be sure of having the same result each time I encrypt the same text. @muntoo - How would you do to "guess" the date of encrpytion?
