this company claim Scrypt mining by ASIC (on crypto currencies who use scrypt hashing as proof of work) scrypt is made to keep ASIC/FPGA attackers away, is that claim expired?
I'm working on a project where following constrains apply: There's no remote database or any other means of storing extra data like random salt When user logins in, only username and password are ...
Being a memory intensive hash, I was wondering if SSD's offer any appreciable performance boost for brute force attacks.
I'm afraid I'll have tomatoes thrown at me for asking this old question, but here goes. After reading that cooking up your own password hash out of existing hashing functions is dangerous over and ...

I've read here that hashing with differents algorithms would be a good idea. Can you confirm that? In your experience, is it useful and safe? Does it entail any security holes?
Given an option , which one should I choose , a HMAC for storing a password securely or a bcrypt or scrypt library?
Assuming that I'm doing password hashing properly and using bcrypt, scrypt or PBKDF2, how should I go about choosing an appropriate difficulty factor? i.e rounds for bcrypt, iterations for PBKDF2 and ...
