[Facets] extending Digest::(MD5|SHA1|...) ?

[Guido De Rosa]

How about extending Digest::MD5 and other message-digest algorithm
classes from the std library?

Some sugar like this would be really sweet:

Digest::MD5::LENGTH #=> 256
Digest::length(:MD5) #=> 256

Digest::MD5.digest('secret', :salt => 'mysalt')

The following would auto-generate a random salt of the optimal length
(which should be same as the hash , i.e. Digest::MD5::LENGTH bits)

Digest::MD5.dgest('secret', :salt => :auto)

Is there some interest in such feature? In such case, I would like to
write/contribute the code and I will report here about any progress.

Regards,
Guido

Some code is here:

It's basically a standard library extension from one of my own
projects, but all the logic might be easily extracted and put into
Facets...

You may write something like

Digest::SHA1.salted_base64digest('secret', 'salt')

or even

Digest::SHA1.salted_base64digest('secret')

with a salt auto-generated,

Cool. I'll have a look the code and see what I can add to Facets.
