ssh-keygen is a standard component of the Secure Shell (SSH) protocol suite found on Unix, Unix-like and Microsoft Windows computer systems used to establish secure shell sessions between remote computers over insecure networks, through the use of various cryptographic techniques. The ssh-keygen utility is used to generate, manage, and convert ...
A 2019 draft of "FIPS 186-5" notes the intention to allow usage of Ed25519 [24] for digital signatures. The 2023 update of Special Publication 800-186 allows usage of Curve25519. [25] In February 2017, the DNSSEC specification for using Ed25519 and Ed448 was published as RFC 8080, assigning algorithm numbers 15 and 16. [26]
Notable uses of Ed25519 include OpenSSH, [19] GnuPG [20] and various alternatives, and the signify tool by OpenBSD. [21] Usage of Ed25519 (and Ed448) in the SSH protocol has been standardized. [22] In 2023 the final version of the FIPS 186-5 standard included deterministic Ed25519 as an approved signature scheme. [15]

If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1271 ahead. Let's start with a few hints.
This output would be produced by a ssh-keygen -r host.example.com. command on the target server by reading the existing default SSH host key (Ed25519). [5] With the OpenSSH suite, the ssh-keyscan utility can be used to determine the fingerprint of a host's key; using the -D will print out the SSHFP record directly. [6]
