Basci HTTP Auth with with the salted SHA512 algorithm rather than MD5???

I read this article on the new salted SHA512 algorithm for hashing passwords. I assume this is local but what about using it in a HTTP Basic Auth irule instead of using MD5. Is this possbile? If so, can a sample irule be posted? Aforementioned article: https://devcentral.f5.com/articles/sha512-passwords

 

Thank you,

  • That could be problematic as you need the salt and hash to verify the correct password. Storing it in table space is an option, but that isn't a permanent filestore and you risk forcing password resets for everyone. If you wanted to go down that route, you'd need to generate a CSPRNG for the salt (for SHA512 it should be at least 64 bytes) and prepend that to your password before hashing with the built-in SHA512 iRules command. rand is not cryptographically secure, but perhaps now with proc support, someone wants to take on building a CSPRNG proc for iRules?
