#Options
#-b “Bits” This option specifies the number of bits in the key. The regulations that govern the use case for SSH may require a specific key length to be used. In general, 2048 bits is considered to be sufficient for RSA keys.
#-e “Export” This option allows reformatting of existing keys between the OpenSSH key file format and the format documented in RFC 4716, “SSH Public Key File Format”.
#-p “Change the passphrase” This option allows changing the passphrase of a private key file with [-P old_passphrase] and [-N new_passphrase], [-f keyfile].
#-t “Type” This option specifies the type of key to be created. Commonly used values are: - rsa for RSA keys - dsa for DSA keys - ecdsa for elliptic curve DSA keys
#-i "Input" When ssh-keygen is required to access an existing key, this option designates the file.
#-f "File" Specifies name of the file in which to store the created key.
#-N "New" Provides a new passphrase for the key.
#-P "Passphrase" Provides the (old) passphrase when reading a key.
#-c "Comment" Changes the comment for a keyfile.
#-p Change the passphrase of a private key file.
#-q Silence ssh-keygen.
#-v Verbose mode.
#-l "Fingerprint" Print the fingerprint of the specified public key.
#-B "Bubble babble" Shows a "bubble babble" (Tectia format) fingerprint of a keyfile.
#-F Search for a specified hostname in a known_hosts file.
#-R Remove all keys belonging to a hostname from a known_hosts file.
#-y Read a private OpenSSH format file and print an OpenSSH public key to stdout.Copyright © 2021 Codeinu
