i like when people use a forum for the purpose it was created, and are then told not to use the forum for the purpose it was created.

A search engine link is still useful as an answer. With search engines it is often a case of knowing what to search for. It also saves storage on the actual forum itself.

Also bear in mind a lot of people are giving their time free of charge to help others by answering questions. Is it too much to ask that people who post questions spend at least a bit of time doing some investigation themselves ? I am not saying Pleigh didn't spend some time investigating but it is always about how you ask the question. ...http://www.catb.org/~esr/faqs/smart-questions.html

If you had been around this forum as long as some of us have...you would realise the ammount of questions that get asked on this forum, that could easily have been solved by simply using a bit of their own initiative.

Google is one of the many tools that are at your desposal to find answers to your questions...it took me literally less than 10 seconds to find the answer to the question which pleigh asked.

I agree that it is good for a user to post this kind of question if it hasn't been asked before on the forum, so now it is here for future reference.

Anyway, at the end of the day, when did i say not to use this forum for this question, i was merely pointing him directly to the answer which he seeked (1st result on Google).

thanks guys for great reactions....i think, pimp, coder were right with their point...brandan has good point...i'll make it easier this time...the reason i posted it here in the forum is because i want to know the reactions of guru's here what the difference are...i can simply search it through google or other search engines, but how many opinions can i get? 3? 4?...i am hoping to get views and opinions of the majority...this forum is really helpful, no doubt...and beginning programmers(like me) are looking forward to be helped by otheres in this forum but not to the extent of spoon feeding...on my personal view, i think the essence of a good forum is good interaction of the members...

you're likely to not get much of a response, as we're tired of answering the question, along with many many many others...

As I stated earlier, answers greatly depend on the question you ask. The question now to be answered is...

"Having looked on the web, GOOGLE etc but am interested in what people on this forum think the difference between encrypting and hashing is ?"

Encryption is a scheme where an text is made unintelligible using a "key". The security of the encyption resides in the key length and decryption process is difficult without proper knowledge of the key.

Hashing is a one way methodology that changes strings into another seemingly unreadble strings. Hash Functions can be designed using a secret key as a parameter along with the message that has to be hashed or with out them (dedicated hash functions MD4,MD5,SHA-1 etc..).

Encryption is two way (you can encrypt and decrypt providing you have the key). Hashing is only one way.

CoderGoblin makes a great point here.

If i had read that time had been taken to research, but the user was still looking for further information, my answer would have been entirely different.

Im more likely to give indepth answers to someone that has had a go at something, and failed...than someone that just cant be bothered and wants the work doing for them.

This isn't directed at pleigh, this is just a general comment.

If I had know that google had been used int he first instance, i obvioulsy wouldn't have directed pleugh to google. We need the info, i know us Mods and Admins are good, but we aren't mind readers :D
