I want to know if there is command line in Ethereum can do the RSA signature verification that we can directly use


In short no. Ethereum uses Elliptic Curves for signatures

You can see all command line options by running: geth help.

  • then can the contract directly do Elliptic Curves signatures verification? – Wang Apr 30 '16 at 1:24
  • You can check elliptic curve signatures (I'm pretty sure it's secp256k1 curve only.. same curve as Bitcoin) with ecrecover. There is no RSA signature verification yet, but that seems to be in the works for some future release ( github.com/ethereum/EIPs/issues/74 ). – stevenh512 Apr 30 '16 at 3:25
  • @wang See this post on signature verification: ethereum.stackexchange.com/questions/2256/… – dbryson May 2 '16 at 0:40
