25519 is an asymetric key using eliptic curves
- pfg 10y agoAs both rockdoe and hannob have mentioned, ed25519 provides the same attack resistance as a 128-bit symmetric cipher. This is even mentioned in the original DJB ed25519 paper: > High security level. This system has a 2^128 security target; breaking it has similar difficulty to breaking NIST P-256, RSA with ≈ 3000-bit keys, strong 128-bit block ciphers, etc. (The same techniques would also produce speed improvements at other security levels.) The best attacks known actually cost more than 2^140 bit operations on average, and degrade quadratically in success probability as the number of bit operations drops.
- mSparks 10y ago->similar difficulty to breaking NIST P-256 which takes our comp sci lab 35 seconds on a cluster of 8 machines. so still no.
- pfg 10y agoIf that's possible, I'm sure you'll have no difficulty finding a public source to cite that states the same.
- mSparks 10y agoAll the public sources I've found say it is secure. Except for the ones recommending 512bit EC's Perhaps you can find the parameters for a 512bit,non NIST EC and we can both be happy? Otherwise I'll stick with 8000 and 15424 RSA thnx.
