support for rsa-oaep and MGF with SHA1 and SHA384 digest method

[Timothy Legge]

Hi

I am attempting to decrypt an  aes256-gcm session key in XML that was encrypted with rsa-oaep using a MGF of mgf1sha1 with a digest hash using sha384

Is this possible with libTom?

As far as I can see there is no method to specify the digest when doing a decrypt.

Hi Tim,

That's not possible at the moment.

libtomcrypt currently only supports the same hash for the MGF and the Label.

Can you try out https://github.com/libtom/libtomcrypt/pull/612 and give
feedback whether that works for you?! Then I'll also add the encrypt part.

Cheers
Steffen
