What is the big difference between implementing a post-quantum sig scheme and implementing ECDSA or RSA into blockchain? Posted: 02 Dec 2018 03:30 AM PST I understand it's harder to implement post quantum signature schemes. Is that correct? And where lies the difficulty? submitted by /u/Oweeeeeeeaiwe [link] [comments]

new program: nacl-cli, similar to salty, a new attempt at replacing PGP (partially) Posted: 02 Dec 2018 09:19 AM PST nacl-cli is an alternative to PGP. This commandline program provides a text-based, serialization format for encrypting/decrypting with Daniel Bernstein's tweetnacl library. In fact, the value added is just the text format. A public key looks like this: ​ nacl.cryp.pub.Hdkh4LrtMb2KfnLAqviyBqpmz4ntKcDCiJh8Pk5kZ89E.yPG ​ It is not spectacularly short, but still a lot shorter than a PGP public key. A crypttext message looks like this: ​ --nacl-crypt--begin-- eph-pub:nacl.cryp.pub.DAnrM3apTQ7pBsZYx6sPkxRtQhWs9pa7taAnnE9NY6jw.Nd9 nonce:nacl.cryp.nonce.FrvHS6NNNndv44LySunkKE8Q5u6f5NRaL.2eU . 8URzXs0ErZ8TqqMZsddai2a+/mRiuTa6BUxkPubMMtsihsPYchtGNxTq --nacl-crypt--end-- ​ The idea is that it can easily be pasted in email and other communication streams. ​ The program does not try to manage keys. That would rather be for a GUI. Dealing with digital signatures is also not the goal of the program. It tries to be a simple encryption/decryption tool that can be used in situations where users would otherwise have to suffer PGP. submitted by /u/mimblezimble [link] [comments]
