If you don't specify a file, you are queried for a filename. iĬonverts the specified Reflection public key to OpenSSH format. pub file extension.) This option can also be used in combination with -e, -i, -l, - p, -y, and -B to specify the input filename.

(A public key is also created and is always given the same name as the private key plus a. Specifies the filename for the generated private key. Uses the specified OpenSSH public or private key to generate a public key in Reflection format. If you do not specify a comment when you create a key, a default comment is created that includes the key type, creator, date, and time. Use quotation marks if the string includes spaces. Specifies information for the comment field within the key file. You can specify the private or public key name, but in either case, the public key must be available. Shows the fingerprint of the specified key in SHA-1 Bubble Babble format. The default for ECDSA keys is 256 bits DSA keys is 1024 bits for RSA it is 2048 bits. To ensure the best choice for your needs, we recommend that you contact your security officer. The length of key you should use depends on many factors, including: the key type, the lifetime of the key, the value of the data being protected, the resources available to a potential attacker, and the size of the symmetric key you use in conjunction with this asymmetric key. Increasing key size slows down the initial connection, but has no effect on the speed of encryption or decryption of the data stream after a successful connection has been made.

Up to a point, a larger key size improves security.
