Module octavo::digest
[−]
[src]
Implementation of popular (and less popular, but fancy) hashing algorithms.
WARNING: Not all of them are cryptographic hash functions and there are known attacks on some of them. Use with careful and always check that the one you choose fits your requirements!
WARNING: If you want to use one of this functions as password hash then you are evil human being and I really hope that I'm not using any of your services.
Cryptographic hash functions
Via Wikipedia:
The ideal cryptographic hash function has four main properties:
- it is easy to compute the hash value for any given message
- it is infeasible to generate a message from its hash
- it is infeasible to modify a message without changing the hash
- it is infeasible to find two different messages with the same hash.
