Willyoumake a separate change for this on which we'll both work or is it additional work on 20030?You can create a separate change, 20030 is focussed on making Libgcrypt mandatory but will not rewrite other parts (in order to make review easier).Alright! I've removed the md4 and rc4 symbols. Don't feel confidentenoughto remove the crypt_des_ecb calls because I'm not sure what is happening exactly, so I'm worried it'll break.Ehh, that indeed needs a closer look. I'll take a look once you finished the patch (to avoid possible conflicts within the file).Looks like wsutil/aes.h is also used by epan/dissectors/packet-dof.c and epan/crypt/airpdcap_ccmp.c for rijndael_encrypt(), so we ought to putthoseon the list as well.Oh right! I grepped for the cipher names based on the filename and missed Rijndael. General remark, when rewriting files, can you try to find a pcap and confirm that the before/after result is the same? You can then add this to the commit message.
I did not find any captures that are appropriate for the rc4 related calls, looks like the captures up on the web are about other (AES) encryption. Removed the Rijndael references in the epan/crypt/* but looks like the information for the sample capture for the DOF protocol ( https://wiki.wireshark.org/SampleCaptures#DOF_.28Distributed_Object_ Framework.29_Protocols) either has the wrong decryption info or the decryption is already broken as it doesn't decrypt in Fedora's stock Wireshark (2.2), so that'll be difficult to verify.
