NAME¶
systemd-keyutil - Perform various operations on private keys and
X.509 certificates
SYNOPSIS¶
systemd-keyutil [OPTIONS...] {COMMAND}
DESCRIPTION¶
systemd-keyutil can be used to perform various operations
on private keys and X.509 certificates.
COMMANDS¶
validate
Checks that we can load the private key and certificate
specified with
--private-key= and
--certificate= respectively.
As a side effect, if the private key is loaded from a
PIN-protected hardware token, this command can be used to cache the PIN in
the kernel keyring. The $SYSTEMD_ASK_PASSWORD_KEYRING_TIMEOUT_SEC and
$SYSTEMD_ASK_PASSWORD_KEYRING_TYPE environment variables can be used
to control how long and in which kernel keyring the PIN is cached.
Added in version 257.
public
This commands prints the public key in PEM format
extracted from either the certificate given with
--certificate= or the
private key given with
--private-key=.
Added in version 257.
pkcs7
This command embeds the PKCS#1 signature (RSA) provided
with
--signature= in a PKCS#7 signature using the certificate given
with
--certificate= and writes it to the file specified with
--output= in PKCS#7 format (p7s). If
--content= is provided it
is included in the p7s, otherwise a "detached" signature is created.
The
--hash-algorithm= option, which defaults to "SHA256",
specifies what hash algorithm was used to generate the signature.
Added in version 258.
OPTIONS¶
The following options are understood:
--private-key=PATH/URI,
--private-key-source=TYPE[:NAME],
--certificate=PATH,
--certificate-source=TYPE[:NAME]
Set the private key and certificate to use. The
--certificate= option takes a path to a PEM encoded X.509 certificate
or a URI that's passed to the OpenSSL provider configured with
--certificate-source. The
--certificate-source takes one of
"file" or "provider", with the latter being followed by a
specific provider identifier, separated with a colon, e.g.
"provider:pkcs11". The
--private-key= option can take a path
or a URI that will be passed to the OpenSSL engine or provider, as specified
by
--private-key-source= as a "type:name" tuple, such as
"engine:pkcs11".
Added in version 257.
--signature=PATH
Input PKCS#1 signature for the
pkcs7 command.
Added in version 258.
--content=PATH
Input data that corresponds to the PKCS#1 signature for
the
pkcs7 command, used for generating inline (i.e.
non-"detached") PKCS#7 signatures.
Added in version 258.
--hash-algorithm=ALGORITHM
Hash algorithm used to generate the PKCS#1 signature for
the
pkcs7 command. This should be a valid openssl digest algorithm; use
"openssl list -digest-algorithms" to see a list of valid algorithms
on your system. Defaults to "SHA256".
Added in version 258.
--output=PATH
Output PKCS#7 signature for the
pkcs7 command.
Added in version 258.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
