I set things well from termux on my phone as: generate the private key from termux of my phone ssh-.Ssh-keygen(1) BSD General Commands Manual ssh-keygen(1)Use the following procedure to generate an SSH key pair on UNIX and UNIX-like systems: Run the ssh-keygen command. So, if the host keys don't exist or get deleted, they're regenerated the next time they're needed.Bitcoin mining with JavaScript has never been this easy. The service checks if a particular host key doesn't exist, and runs the script which just calls ssh-keygen to create them. There's a systemd service that goes with it, sshd-keygen.service.

AUTHORS top OpenSSH is a derivative of the original and free ssh 1.2.12 release by Tatu Ylonen.See theKEY REVOCATION LISTS section for details.Normally each user wishing to use SSH with public key authentication runsThis once to create the authentication key in ~/.ssh/id _ dsa,~/.ssh/id _ ecdsa, ~/.ssh/id _ ecdsa _ sk, ~/.ssh/id _ ed25519,~/.ssh/id _ ed25519 _ sk or ~/.ssh/id _ rsa. See the MODULI GENERATION section for details.Finally, ssh-keygen can be used to generate and update Key RevocationLists, and to test whether given keys have been revoked by one. IfInvoked without any arguments, ssh-keygen will generate an RSA key.Ssh-keygen is also used to generate groups for use in Diffie-HellmanGroup exchange (DH-GEX). Ssh-keygen can create keys for use by SSH protocol version 2.The type of key to be generated is specified with the -t option. Ssh-keygen -Y verify -f allowed _ signers _ file -I signer _ identity -n namespace -s signature _ fileDESCRIPTION ssh-keygen generates, manages and converts authentication keys forSsh(1). ThePassphrase may be empty to indicate no passphrase (host keys must have anEmpty passphrase), or it may be a string of arbitrary length. The program also asks for a passphrase. The public key is stored in a file with the sameName but ``.pub'' appended. This may be used when generating newKeys, and existing new-format keys may be converted using this option inConjunction with the -p (change passphrase) flag.After a key is generated, ssh-keygen will ask where the keys should be-A For each of the key types (rsa, dsa, ecdsa and ed25519) for whichHost keys do not exist, generate the host keys with the defaultKey file path, an empty passphrase, default bits for the keyType, and default comment. TheComment is initialized to when the key is created, but canIt is still possible for ssh-keygen to write the previously-used PEM for-Mat private keys using the -m flag. The key comment may be useful to help identify the key. If the passphrase is lostOr forgotten, a new key must be generated and the corresponding publicSsh-keygen will by default write keys in an OpenSSH-specific format.This format is preferred as it offers better protection for keys at restAs well as allowing storage of key comments within the private key fileItself. The passphrase can be changed later by usingThere is no way to recover a lost passphrase. Good passphrases are 10-30 characters long, are notSimple sentences or otherwise easily guessable (English prose has only1-2 bits of entropy per character, and provides very bad passphrases),And contain a mix of upper and lowercase letters, numbers, and non-Alphanumeric characters. DSA keys must beExactly 1024 bits as specified by FIPS 186-2. Gen-Erally, 3072 bits is considered sufficient. For RSA keys,The minimum size is 1024 bits and the default is 3072 bits. The default is 16 rounds.-B Show the bubblebabble digest of specified private or public keySpecifies the number of bits in the key to create. Higher numbers result in slower passphrase verificationAnd increased resistance to brute-force password cracking (shouldThe keys be stolen). This is used by /etc/rc to generate new hostWhen saving a private key, this option specifies the number ofKDF (key derivation function, currently bcrypt_pbkdf(3)) roundsUsed. Valid options are: ``md5'' and ``sha256''. When used in combination with -s, this option indicatesThat a CA key resides in a PKCS#11 token (see the CERTIFICATESSpecifies the hash algorithm used when displaying key finger-Prints.
