Re: What's best - SHA256 or Scrypt?

Quote

In cryptography, encryption is the process of encoding messages (or information) in such a way that eavesdroppers or hackers cannot read it, but that authorized parties can.

Are you aware that PGP uses SHA-2 as it's encryption algorithm.

Okay, get this through your thick skull:

Hash function -> One way message digest. Cannot go from digest to input without brute force (barring attacks against the algo).
Encryption algorithm -> A reversible encoding that can only be reversed with additional information, the key.

PGP may very well use SHA-2, but it's for hashing, not for encryption.

May I ask what your background or education is for programming/computers? If you're self learned that's fine too - I've personally met 16 year old hackers all self learned who hacked in NASA servers and the pentagon.

I'm self-taught and have implemented many encryption and hashing algorithms in code. I taught my math teacher in high school crypto, as a matter of fact.

That's awesome dude. Respect.

That's a hard language to master. I took a C++ class in college and I was a 3.8 GPA student and that class was way harder than I expected - barely got a B+ although i bypassed buying the 3 required textbooks which may have helped a bit.

It was my first computer class and I jumped over the pre-requisites to take it but still, it was an intro class. I have a newfound respect for hackers and programmers, especially if they're self taught.
