  • Getting the public key corresponding to a particular private key, through the methods provided for by OpenSSL, is a bit cumbersome. An easier way to do it is to use phpseclib, a pure PHP RSA implementation:
  • Both raw private and public keys can be obtained for X25519, Ed25519, X448, Ed448. Raw private keys only can be obtained for HMAC, Poly1305 and SipHash Fixes openssl#6259 mattcaswell mentioned this issue Jun 1, 2018
  • ECDH is used for the purposes of key agreement. Suppose two people, Alice and Bob, wish to exchange a secret key with each other. Alice will generate a private key d A and a public key Q A =d A G (where G is the generator for the curve). Similarly Bob has his private key d B and a public key Q B =d B G.

  • keychain expects public key files to exist in the same directory as their private counterparts, with a .pub extension. If the private key is a symlink, the public key can be found alongside the symlink or in the same directory as the symlink target (this capability requires the readlink command to be available on the system).
  • The OpenSSH public key format is NOT PEM, and although it is base64, as your own link describes, the data format encoded by that base64 is not the same as used in the PEM files used in OpenSSL and that library. – dave_thompson_085 Sep 18 '19 at 7:21

Car was driving then stopped acceleratingThe "ssh-ed448" key format has the following encoding: string "ssh-ed448" string key Harris & Velvindron Expires February 13, 2019 [Page 2] Internet-Draft Ed25519 for SSH August 2018 Here 'key' is the 57-octet public key described by [RFC8032], Section 5.2.5 [RFC8032]. 5. The following example creates a key pair called sgKey.snk. sn -k sgKey.snk If you intend to delay sign an assembly and you control the whole key pair (which is unlikely outside test scenarios), you can use the following commands to generate a key pair and then extract the public key from it into a separate file. First, create the key pair:
pk is the encoded Ed25519 public key as defined by draft-josefsson-eddsa-ed25519-03. So I am trying to get the actual public key value (32 bytes) from the public key, and then encode them.

It can be also used to store secure data in database.

This seems to accept the openSSL generated public key, but ultimately results in non-matching client and server SecretKeys. I normally don't post for help, choosing instead to just keep hammering away at a problem till I win, but this is going on 3 weeks and I have a deadline coming up. Any help would be appreciated.

  • This creates a key file called private.pem that uses 1024 bits. This file actually have both the private and public keys, so you should extract the public one from this file: $ openssl rsa -in private.pem -out public.pem -outform PEM -pubout . You'll now have public.pem containing just your public key, you can freely share this with 3rd parties.
