I am trying to crack a SHA-256 hash but I am not sure how to approach this in an efficient way. The following is known of the original non-hashed content:
- 64 characters long
- only consists 0-9 and a-z (no capital letters)
- the original content does not consist dictionary words
- the hash is not salted
I have done some reading on the subject of cracking hashes and some information I have read is conflicting. For example, one said on a public forum that SHA-256 is virtually impossible to crack while the other said that it's a rather poor method for password storage as it could be cracked easily.
Is SHA-256 a safe method to hash passwords with (if not, what are the alternatives) and how do I crack a given hash in an efficient way (assuming the given criteria above).
Thanks in advance!
