DSA keys must be ex-Īctly 1024 bits as specified by FIPS 186-2. Gen-Įrally, 3072 bits is considered sufficient. The minimum size is 1024 bits and the default is 3072 bits. Specifies the number of bits in the key to create. B Show the bubblebabble digest of specified private or public key

Higher numbers result in slower passphrase verificationĪnd increased resistance to brute-force password cracking (should KDF (key derivation function, currently bcrypt_pbkdf(3)) rounds When saving a private key, this option specifies the number of This is used by /etc/rc to generate new host If -f has also been specified, itsĪrgument is used as a prefix to the default path for the result. Key file path, an empty passphrase, default bits for the key Host keys do not exist, generate the host keys with the default A For each of the key types (rsa, dsa, ecdsa and ed25519) for which Keys, and existing new-format keys may be converted using this option inĬonjunction with the -p (change passphrase) flag.Īfter a key is generated, ssh-keygen will ask where the keys should be It is still possible for ssh-keygen to write the previously-used PEM for. TheĬomment is initialized to when the key is created, but can be The key comment may be useful to help identify the key. This format is preferred as it offers better protection for keys at restĪs well as allowing storage of key comments within the private key file Ssh-keygen will by default write keys in an OpenSSH-specific format. Or forgotten, a new key must be generated and the corresponding public There is no way to recover a lost passphrase. The passphrase can be changed later by using the -p Ple sentences or otherwise easily guessable (English prose has only 1-2īits of entropy per character, and provides very bad passphrases), andĬontain a mix of upper and lowercase letters, numbers, and non-alphanu. Good passphrases are 10-30 characters long, are not sim. Ries of words, punctuation, numbers, whitespace, or any string of charac. Passphrase is similar to a password, except it can be a phrase with a se. Passphrase may be empty to indicate no passphrase (host keys must have anĮmpty passphrase), or it may be a string of arbitrary length. The public key is stored in a file with the same Normally this program generates the key and asks for a file in which to Trator may use this to generate host keys, as seen in /etc/rc. This once to create the authentication key in ~/.ssh/id_ dsa, Normally each user wishing to use SSH with public key authentication runs KEY REVOCATION LISTS section for details. Lists, and to test whether given keys have been revoked by one.
