Description

AlgorithmRsaOaep uses RSAES_OAEP_SHA_Decryptor which is OAEP padding with SHA1.
https://github.com/named-data/ndn-group-encrypt/blob/master/src/algo/rsa.cpp#L89

Recently, compromising attacks have been found for SHA1. Alex Halderman says we should change to OAEP padding with SHA256. Currently, the code uses the cryptopp definition:

typedef RSAES<OAEP<SHA> >::Decryptor RSAES_OAEP_SHA_Decryptor;

I don't see a typedef for SHA256, but I think it would be possible to define AlgorithmRsaOaepWithSha256 which uses:

RSAES<OAEP<SHA256> >
