It describes splitting a key into secret shares, requiring multiple parties to cooperate, and using client/server controls for limits, revocation, and rotation. The approach applies to blockchains using ECDSA and EdDSA, including Bitcoin and Ethereum. ### Source excerpt This post is about the paper "Improving security for users of decentralized exchanges through multiparty computation", by Robert Annessi and Ethan Fast. The paper introduces an effective algorithm for secure, collaborative signature generation using threshold signatures, and an API-key based client/server protocol that allows user-specific limits and restrictions as well as key revocations and rotations. The method supports all blockchains that use ECDSA and EdDSA signatures, which includes Bitcoin, Ethereum and the majority of popular cryptocurrencies. ## Let's Encrypt Announces Public Certificate Release Starting September 14, 2015 DevFeed: [Let's Encrypt Announces Public Certificate Release Starting September 14, 2015]() Original publisher: [Read original article]() Author: andreacorbellini Published: 2015-06-16T18:20:00Z Content type: news Language: en Sources: [Andrea Corbellini]() Topics: [certificates](), [ECDSA]() Tags: [automated](), [cryptography](), [ecdsa](), [free](), [launch](), [let-s-encrypt](), [open](), [rsa](), [security](), [technical](), [tls](), [web]() ### AI overview Let's Encrypt announced that its certificates would be released to the public starting the week of September 14, 2015.

It then compares the need for elliptic-curve cryptography with RSA-based cryptosystems. ### Source excerpt This post is the fourth and last in the series ECC: a gentle introduction. In the last post we have seen two algorithms, ECDH and ECDSA, and we have seen how the discrete logarithm problem for elliptic curves plays an important role for their security.

I always used RSA keys but wanted to give a try to ECDSA so I wanted to give it a try (test performance, etc). Here is how I've done it. Firstly find your favorite curve. A short tip about bit length and complexity could be found here. From it you will now that using 256 bit ECDSA key should be enough for next 10-20 years.
