I know there are several encryption examples/scripts/functions. I just wondered which one is the most secure/reliable.

And how secure they are on say a level of 1-10. I mean if I was to encypt some data using them and save it locally, if someone got hold of the local file what would the chances be of it being hacked??

I would have to say MD5 is the most secure because no matter how long the string you want to encrypt is, it is always put in a 32 len encrypted string. I would rate it about a 9.2 (The longer the string, the more secure IMHO)

Any other opinions or suggestions?

AES is the current "best" balance between high security and speed / complexity. Other currently viable options include Blowfish, Twofish, and 3DES.

You can always trade increased security for decreased performance by using chained cyphers, e.g. AES with Key 1, the output of which is then run through AES again using Key 2 (effectively increasing the length of the key). This of course can be continued past the point of sanity leading to effectively write-only memory mentioned by [VxE].

Personally I used chained AES-128 + TwoFish for the TruCrypt volume on my USB flash drive. The weak link of course is my choice of password, which is only rated to approximately 68 bits.

i don't know much about encryption but i saw that everywhere saying MD5 is unsecure

I agree with greynite, AES is the most suitable algorithm for encryption. For hashing I would recommend crc32 over md5 because its much faster.
