sshkeygen: minimal version of the OpenSSH ssh-keygen(1) utility. This was primarily written as a proof-of-concept and test of the sshkey[1] package. Usage: sshkeygen [flags] -b bitsize bitsize of key to create -c comment key comment -f filename input keyfile -l show fingerprint of keyfile -t keytype type of key to create By default, sshkeygen will generate 256-bit ECDSA keys. Options: -b bitsize This selects the size of the key to be generated, in bits. For ECDSA keys, valid sizes are 256, 384, or 521 bits. For RSA keys, a minimum size of 2048 bits is enforced. -c comment Specify a comment for the generated key. If no comment is provided, the default commend 'user@host' is used. -f filename Specify the filename of the SSH key file. If a key is being generated, the private key is stored in "filename", and the public key is stored in "filename.pub". -l Display the fingerprint for an SSH public key. Currently, this fails if the file is a private key. -t keytype Specify the type of key to create. Permissible values are "rsa" and "ecdsa". License: sshkeygen is released under an ISC license.
