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 The information in this manpage may be invalid or outdated.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

Print program version

Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options.

DIAGNOSTICS¶

See the --log-file , --verbose , --trace and --debug options.

REPORTING BUGS¶

Report bugs to <bug-lsh@gnu.org>.

ENVIRONMENT¶

LSH_YARROW_SEED_FILE may be used to specify the random seed file.
