A password hash is an encrypted sequence of characters obtained after applying certain algorithms and manipulations on user provided password, which are generally very weak and easy to guess.There are many such hashing algorithms in java also, which can prove really effective for password security. Note: Please remember that once this password hash is generated and stored in database, you can not convert it back to original password.Also, It is not collision resistant: this means that different passwords can eventually result in the same hash. So, please focus on how it is applied rather than its relation with MD5.Still, if you are using MD5 hash then consider adding some salt to your security. Wikipedia defines salt as random data that are used as an additional input to a one-way function that hashes a password or pass-phrase.Note that if a seed is not provided, it will generate a seed from a true random number generator (TRNG).Now, lets look at the modified MD5 hashing example: Important: Please note that now you have to store this salt value for every password you hash.Also, you might heard of term crazy hashing and salting.It generally refer to creating custom combinations like: Do not practice these things.

Now these blocks are processed by the MD5 algorithm, which operates in a 128-bit state, and the result will be a 128-bit hash value.This value determines how slow the hash function will be.When computers become faster next year we can increase the work factor to balance it out.But it also means that it is susceptible to brute-force and dictionary attacks.Rainbow tables with words and hashes generated allows searching very quickly for a known hash and getting the original word.
