Aug 18, 2020 · ECDSA is gaining popularity but seems to generally be frowned upon by cryptographers due to how elliptical curve cryptography was implemented, with concerns around implementation difficulty due to the use of random values. It has a better reputation than RSA, but cryptographers are still advocating the migration to EdDSA.
