Is marking it read only sufficient or is something else required.

Re: How does one encrypt an MP3 file?
I assume you are talking about an audio as oppose to a music file?
As I am sure you know to encrypt means to lock the file so that no one else can open/unlock the file to listen to it, except the person with the password or encryption key. Is that what you really want?
It would help us to understand, if you gave us the application/situation you are trying to use the file in. -
Re: How does one encrypt an MP3 file?
I am talking about a music file...I don't want to have to go through all the trouble of a password. Just make it so that peopel can't share the file after they download it... will designating it read only do that.Comment

Re: How does one encrypt an MP3 file?
If you give out the actual file, and they can play it, then they can also share it. The only way I personally know to accomplish what you are trying to do, is to stream the song from your web site or a P2P server that have a built in music file player (ex: Mp3 or WMA), so that the file plays from the site itself and does not physically play from any other person's hard drive. In this case read-only will buy you nothing. Maybe someone else out there has a better solution, but that is what I suggestg for now. Also, encrypting the file will buy you very little in this case, if the person also pass on the password or key that you provided to them. Once you un-encrypt the file, it is just like any other file to do with as one please.Comment

Re: How does one encrypt an MP3 file?
Nope read only just means they cant modify the original (and it only takes 2 seconds to fix that by changing the read options on the file properties).
Since you said "encrypt" the best option out there to lock a file with real encryption is something called PGP (http://web.mit.edu/network/pgp.html)
Another option would be to create a .zip file and password protect the file.
None of those seem to fit your needs. Maybe you can give us some details on what you want to do in detail and we could make some suggestions based on your needs.

Re: How does one encrypt an MP3 file?
I don't know how else to describe it as I am not technical. I would like the person to be able to download the file (MP3) play it on their computer or Ipod but NOT be able to share or pass the file on to anyone else.Comment

Re: How does one encrypt an MP3 file?
This is something that has been driving the record industry frack'n crazy for years now. There really isnt a solution for what you are looking for. Once you put a file in electronic format it can be hacked or reverse engineered to remove any copy protections you put on it. If big labels like Sony cant figure out a way with their huge bugets/resources then I don't think you will fare much better.
The only solution the record companies have found is to sue everybody from kids to grandparents for file sharing (may the RIAA rot in *censored* hehe).
Jkid's idea was a good one but it would require you 'stream' media to your customers (which could be very bandwidth intentsive depending on the number of users and size of files). You would need your own web server or rent one to do this kind of webcast.

Re: How does one encrypt an MP3 file?
Woe, this is complex...the whole idea here is so that people can download and play in their Ipods without being able to transfer files. How do people like itunes do it.Comment

Re: How does one encrypt an MP3 file?
Ipod is a proprietary file format. By the way, it is not true that you can't copy Ipod music files. There are ways around their protection also. It is just more difficult for the novice to do, but it is hacked all the time. Many people out there in-the-know, do it all the time.
If you allow people to download the file anyway, all someone needs to do is send a link to their friend as to where to download their own copy, and they still have not directly shared your file, either way you get screwed.
Why don't you just appeal to the better nature of most people and ask them please NOT to share the file?Comment

Re: How does one encrypt an MP3 file?
See info below, and no, it doesn't prevent people from sharing files.Originally posted by Tropicana:Please tell me more about PGP. Does it prevent people from sharing files?
PGP is a security technology which allows us to send email that is authenticated and/or encrypted.
Authentication confirms the identity of the sender or a message. For example if we were asked to amend a website we need to be sure that it is the client who requested that amendment.
Encryption scrambles the contents of a message so that only the intended recipients can read it. If the message is intercepted whilst travelling over the internet then there is no danger that its contents (maybe a password or some customer details) will be revealed.
How it works
Each user of PGP has a public and a private key. They are generated in matched pairs: a public key only ever works with its twin private key.
A user's public key is not a secret and can be distributed widely. Our public keys are available via the links on the right. A public key is used in two ways:
Alice can authenticate a signed message from Bob using his public key. If the message matches Bob's public key then Alice can be sure that the message came from Bob.
Alice can send a secure message to Bob by encrypting the message using Bob's public key. The only person who can decrypt the message is Bob.
A user's private key however must be kept secret, and is protected by a pass phrase (like a pass-word but longer). A private key also has two uses:
Bob can send an authenticated message to Alice by signing it with his private key. Since Bob is the only person who has his private key (and the pass phrase that protects it), Alice knows that if the message matches Bob's public key, then it must have been sent by Bob.
Bob can read a secure message sent by Alice by decrypting it with his private key.

As the other's have pointed out, there really is no easy way of doing what you are tying to accomplish. Just ask the major electronic companies who are still trying.aka ChurchDude. I want that moniker back! Until then....
