It is rather safe to assume, though, that the SHA2 family with its most prominent members SHA-256 und SHA-512, is better than SHA1. When storing password hashes, it is a good idea to prefix a salt to the password before hashing, to avoid the same passwords to hash to the same values and to avoid the use of rainbow tables for password recovery. . /10/2014This video explains the concept of hashing and SHA-256 for newbies.

SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA). They are built using the Merkle–Damgrd structure , from a one-way compression function itself built using the Davies–Meyer structure from a …. One outdated concern weighed against SHA-3 is a slower hashing speed than its predecessors. This is fair, but only with regards to software. When it comes to hardware, SHA-3 easily outpaces SHA-1 and SHA-2, and hashing is increasingly occurring within hardware components.

Not only is SHA-256 not an encryption algorithm, it is a cryptographic hash function, so my question was a little flawed to begin with, but the amount of time it would take to brute-force a single SHA256 hash is (currently) much too long even with the most advanced ASIC miners available today.

SHA-256 is a member of the SHA-2 cryptographic hash functions designed by the NSA. SHA stands for Secure Hash Algorithm. Cryptographic hash functions are mathematical operations run on digital data; by comparing the computed (the output from execution of the algorithm) to a known and expected hash value, a person can determine the data's integrity.
