DSA is deprecated in OpenSSH 7.0
ECDSA is not supported by GNOME Keyring.
Ed25519 is not supported by GNOME Keyring.
SSH Keys, in Arch Linux Wiki
As of July 10, 2015,
GNOME Keyring does not handle ECDSA  and Ed25519  keys. Users will have to turn to other SSH agents or stick to RSA keys. These keys are used only to authenticate you; choosing stronger keys will not increase CPU load when transferring data over SSH.

The security impact of a new cryptographic library; In Proceedings of LatinCrypt 2012; 2012-07-25; 18 pages. Abstract
This paper introduces a new cryptographic library, NaCl, and explains how the design and implementation of the library avoid various types of cryptographic disasters suffered by previous cryptographic libraries such as OpenSSL. Specifically, this paper analyzes the security impact of the following NaCl features: no data flow from secrets to load addresses; no data flow from secrets to branch conditions; no padding oracles; centralizing randomness; avoiding unnecessary randomness; extremely high speed; and cryptographic primitives chosen conservatively in light of the cryptanalytic literature.
