Description

« Hide

I would like to ask if there are plans to implement "slow" cryptographic functions (hashes) (like PBDKF2, bcrypt, scrypt) for password generating / stretching?

If so, when might they be expected?
This would be very useful for generating / verifying passwords directly in PSQL, without the need to create a UDR.

I searched the documentation and the internet, but besides the discussion in the topic "HASH function (~~CORE-4436~~)"
I did not find anything about this in relation to Firebird...

There are no plans to add any more builtin functions to FB4 (or we will never release). But what about next version - why not?

Excellent, it would be great if these functions / hashes appeared in Firebird 5, and even better, in 4.1 (or what is the next minor version will be in the FB4 branch), if it possible :)

Thank you!
