Title: IS SHA256 & Scrypt the same in encryption?
Post by: JohnyBigs on May 14, 2013, 09:26:35 PM
As the title says are they the same security wise? Is scrypt based off of sha256?

Thanks

No, they are different hash algorithms.

yes scrypt uses SHA256 internally

Yes they are.. that is why they gave them the same names... don't let anyone tell you differently.

While true in a literal sort of sense, scrypt does not use SHA-256 as its core mixing function.  It uses salsa20 for that.  scrypt uses HMAC-SHA-256 once at the beginning and once at the end of the algorithm, but salsa20 is the meat 'n' potatoes.

Seriously If someone cannot even be bothered to do the least amount of research possible, then we as professionals should assist them as much as possible on their journey of laziness

It is nothing to do with being a troll, it is about trying to instill the requirement for a little research before posting on a subject.
