Is a RFC4716 formatted key?

RFC 4716 specifies a standard format for storing SSH-2 public keys on disk. Some SSH servers (such as ssh.com's) require a public key in this format in order to accept authentication with the corresponding private key.

What is the rfc4716?

Abstract. This document formally documents an existing public key file format in use for exchanging public keys between different Secure Shell (SSH) implementations. In addition, this document defines a standard textual representation for SSH public key fingerprints.

What is OpenSSH key format?

The OpenSSH public key format

The public key saved by ssh-keygen is written in the so-called SSH-format, which is not a standard in the cryptography world. It's structure is ALGORITHM KEY COMMENT , where the KEY part of the format is encoded with Base64. For example.
