Oct 01, 2020 · Conversion between names (for example Ed25519) and OIDs (18.104.22.168) A specific trick worth mentioning, that we stumbled upon, is that there are two versions of encoding/decoding format of EdDSA. A version 1 and a version 2, where different software implementation, for example OpenSSL, produces the v1 format, while others produce the (newer ...

In :crypto.generate_key(:ecdh, :ed25519) ecdh refers to all kinds of eliptic curves and then we use x25519. While in :crypto.sign(:eddsa, :sha256, msg, [priv_key, :ed25519]) we have special function for Edwards curves, in which we use ed25519. I hope it makes a bit more sense.
Jan 30, 2014 · This key exchange method is the default when both the client and server support it. * ssh(1), sshd(8): Add support for Ed25519 as a public key type. Ed25519 is a elliptic curve signature scheme that offers better security than ECDSA and DSA and good performance. It may be used for both user and host keys.
Some keys types support a "raw" serialization. Currently the only supported raw format is Ed25519, where the public key and private key formats are those specified in RFC 8032. Note the RFC 8032 private key format is the 32-byte prefix of ED25519_sign's 64-byte private key.
Download and install the OpenSSL runtimes. If you are running Windows, grab the Cygwin package. OpenSSL can generate several kinds of public/private keypairs. RSA is the most common kind of keypair generation.
