NAME

lsh-keygen - Generates a keypair and write it on stdout.

SYNOPSIS

lsh-keygen [OPTION...]

DESCRIPTION

CAUTION! The information in this manpage may be invalid or outdated. For authorative information on lsh, please see it’s Texinfo manual (see the SEE ALSO section).
Generates a new private key for the desired algorithm and security level and write it on stdout.
You will usually want to pipe the new key into a program like lsh-writekey, to split it into its private and public parts, and optionally encrypt the private information.

OPTIONS

-a, --algorithm=Algorithm
DSA or RSA. Default is to generate RSA keys
-l, --nist-level=Security level
For DSA keys, this is the NIST security level: Level 0 uses 512-bit primes, level 8 uses 1024 bit primes, and the default is 8. For RSA keys, it’s the bit length of the modulus, and the default is 2048 bits.
--server
Use the server’s seed-file
--debug Print huge amounts of debug information
--log-file=File name
Append messages to this file.
-q, --quiet
Suppress all warnings and diagnostic messages
--trace Detailed trace
-v, --verbose
Verbose diagnostic messages
-?, --help
Give this help list
--usage Give a short usage message
-V, --version
