【實用生產應用app】Hpass|最夯免費app-gigacircle

Hpass was inspired by Supergenpass. It works exactly the same way, except it uses an algorithm that you can reproduce in one single command line with openssl:

$ echo -n $value | openssl dgst -$method -hmac $key -binary | openssl enc -base64 | cut -c1-$len

The algorithm used by Hpass is also more secure: it uses a keyed-hash message authentication code (HMAC). To quote Wikipedia: "The design of the HMAC specification was motivated by the existence of attacks on more trivial mechanisms for combining a key with a hash function". This application was designed out of the belief that, when it comes to security, it is always better to rely on standard algorithms rather than on custom implementations.
