why is crypt package missing dsa, rsa, elgamal, etc?

This is my first-ever query in this forum - please be kind !

 

I've been poking around in the GRUB2 code lately, and noticed that part of
the libgcrypt package doesn't get included in the built modules.  I see how
the Python script translates the standard libgcrypt source files into new
ones that can compile in the GRUB build environment, but I also notice that
DSA, RSA, ElGamal, ECC, PrimeGen(?) do not actually get compiled.  Perhaps
this is because they rely on some other functionality that isn't present,
such as MPI (multiple-precision integers) ?  (a side effect is that several
source files are translated and then not used.)

 

What would it take to get them working?  Has anyone looked at this before to
size it up?

 

I have an application to verify a DSA signature during the bootloader, and
without it I'll have to propose a different approach to my customer.

 

Thanks,

Jordan

Just nobody worked on them yet. We needed ciphers and hashes for some
purposes so they were imported. If you need asymetric patches are
welcome to include them.
