CREATESIGNERKEY(8) CREATESIGNERKEY(8)
NAME
createsignerkey - create signer key on authentication server
SYNOPSIS
auth/createsignerkey [ -a alg ] [ -f keyfile ] [ -e expiry ]
[ -b bitsize ] name
DESCRIPTION
Createsignerkey creates public and private keys that are
used by a server acting as `signer' to generate certificates
for users. Name appears as signer in each certificate. The
expiry date has the form ddmmyyyy, is converted to seconds
since the epoch (see daytime(2)) and stored in the keyfile;
by default the server's certificate never expires.
The key will be bitsize long (default: 512 bits) with a min-
imum of 32 bits and a maximum of 4096 bits. Keyfile is the
file in which the server stores its keys; the default is
/keydb/signerkey, and many authentication programs such as
logind(8) by default expect to find their server key there.
Creating a signer's default key afresh typically invalidates
all certificates previously issued by that signer, because
their signatures will not verify. The mode of the keyfile
should be set to be readable only by the user running those
programs.
The -a option specifies the signature algorithm. Currently
alg can be either elgamal or rsa. RSA keys are now used by
default.
