IPSEC_NEWHOSTKEY(8) Executable programs IPSEC_NEWHOSTKEY(8) NAME ipsec_newhostkey - generate a new raw RSA authentication key for a host SYNOPSIS ipsec newhostkey [[--quiet] | [--verbose]] [--nssdirnssdir] [--pass- word password] [--bits bits] [--curve curve] [--keytype rsa|ecdsa] [--seeddev device] DESCRIPTION newhostkey generates an RSA public/private key pair suitable for authenti- cating this host is generated and stored in the NSS database. See ipsec_showhostkey(8) for how to extract the public key from the NSS database. Output Options --quiet The --quiet option suppresses both the rsasigkey narrative and the ex- isting-file warning message. --nssdir nssdir The --nssdir option specifies the NSS DB directory where the certifi- cate key, and modsec databases reside (default /usr/local/etc/ipsec.d) --password password The --password option specifies a module authentication password that may be required if FIPS mode is enabled. --bits bits The --bits option specifies the number of bits in the RSA key; the cur- rent default is a random (multiple of 16) value between 3072 and 4096. The minimum allowed is 2192. --curve curve The --curve option specifies the named curve used in the ECDSA key; the current default is secp256r1. See ipsec_ecdsasigkey(8) for the avail- able curve names. --keytype rsa|ecdsa The --keytype option specifies the type of key, which can either be rsa (RSA) or ecdsa (ECDSA); if omitted the current default is rsa. --seeddev device The --seeddev is used to specify the random device (default /dev/random used to seed the crypto library RNG.

Updated by Paul Wouters BUGS As with rsasigkey, the run time is difficult to predict, since depletion of the system's randomness pool can cause arbitrarily long waits for random bits for seeding the NSS library, and the prime-number searches can also take unpredictable (and potentially large) amounts of CPU time.
