Hashcode to readable string format

[Former Member]

Hello Everyone,

I need a function module or any code for converting from hashcode to string. I Googled a lot but could not find the solution.

Example:

B35640911EBA4565 is my hash code. After converting I should get "qwer123!" as output string. So how can I convert? And the hash key is of type RAW(8).

Regards

Not possible. Hash is a one way function.

Imagine, a 1gb file can have RAW8 hash. If reversing was possible, it would be world's best compression algorithm.

As per definition, the result of a cryptographic hash function is/should be irreversible, i.e. one cannot/shouldn't be able to retrieve the plain text password from the hash value.
