ECDSA-SK,Įd25519 and Ed25519-SK keys have a fixed length and the -b These three values for ECDSA keys will fail. Selecting from one of three elliptic curve sizes: 256, 384 Keys must be exactly 1024 bits as specified by FIPS 186-2.įor ECDSA keys, the -b flag determines the key length by Generally, 3072 bits is considered sufficient.

Verification and increased resistance to brute-force Higher numbers result in slower passphrase Of KDF (key derivation function, currently bcrypt_pbkdf(3)) When saving a private key, this option specifies the number Used by /etc/rc to generate new host keys. If -f has alsoīeen specified, its argument is used as a prefix to theĭefault path for the resulting host key files. The default key file path, an empty passphrase, defaultīits for the key type, and default comment. Which host keys do not exist, generate the host keys with A For each of the key types (rsa, dsa, ecdsa and ed25519) for Using this option in conjunction with the -p (change passphrase)Īfter a key is generated, ssh-keygen will ask where the keys should Generating new keys, and existing new-format keys may be converted PEM format private keys using the -m flag. It is still possible for ssh-keygen to write the previously-used The key is created, but can be changed using the -c option. This format is preferred as it offers better protectionįor keys at rest as well as allowing storage of key comments within Ssh-keygen will by default write keys in an OpenSSH-specificįormat. Lost or forgotten, a new key must be generated and theĬorresponding public key copied to other machines. There is no way to recover a lost passphrase. Sentences or otherwise easily guessable (English prose has only 1-2īits of entropy per character, and provides very bad passphrases),Īnd contain a mix of upper and lowercase letters, numbers, and non-Īlphanumeric characters.
