based on EIP-198 and a question asked here After EIP 198 introduction, how much gas is required for RSA signature verification in solidity? it should now be possible to do RSA signature verification in Ethereum.
I want to do that on a private chain within a smart contract. Sadly I can't find any more details on how to implement that, besides the EIP description.
Is there an example contract available somewhere or a blog post which explains how to use EIP198 to achieve rsa signature verification within solidity?
If someone could point me to a description with more solidity-related details than https://github.com/ethereum/EIPs/blob/master/EIPS/eip-198.md would be highly appreciated, I can't find anything other than the EIP itself.
