363 @subheading Generating private keys
364 To create an RSA private key
, run
:
366 $ certtool
--generate
-privkey
--outfile key.pem
--rsa
369 To create a DSA or elliptic
curves (ECDSA
) private key use the
370 above command combined with
'dsa' or
'ecc' options.
372 @subheading Generating certificate requests
373 To create a certificate
request (needed when the certificate is issued by
376 certtool
--generate
-request
--load
-privkey key.pem \
377 --outfile request.pem
380 If the private key is stored in a smart card you can generate
381 a request by specifying the private key object URL.
383 $ .
/certtool
--generate
-request
--load
-privkey
"pkcs11:..." \
384 --load
-pubkey
"pkcs11:..." --outfile request.pem
388 @subheading Generating a self
-signed certificate
389 To create a self signed certificate
, use the command
:
391 $ certtool
--generate
-privkey
--outfile ca
-key.pem
392 $ certtool
--generate
-self
-signed
--load
-privkey ca
-key.pem \
393 --outfile ca
-cert.pem
396 Note that a self
-signed certificate usually belongs to a certificate
397 authority
, that signs other certificates.
399 @subheading Generating a certificate
400 To generate a certificate using the previous request
, use the command
:
402 $ certtool
--generate
-certificate
--load
-request request.pem \
403 --outfile cert.pem
--load
-ca
-certificate ca
-cert.pem \
404 --load
-ca
-privkey ca
-key.pem
407 To generate a certificate using the private key only
, use the command
:
409 $ certtool
--generate
-certificate
--load
-privkey key.pem \
410 --outfile cert.pem
--load
-ca
-certificate ca
-cert.pem \
411 --load
-ca
-privkey ca
-key.pem
414 @subheading Certificate information
415 To view the certificate information
, use
:
417 $ certtool
--certificate
-info
--infile cert.pem
420 @subheading PKCS #
12 structure generation
421 To generate a PKCS #
12 structure using the previous key and certificate
,
424 $ certtool
--load
-certificate cert.pem
--load
-privkey key.pem \
425 --to
-p12
--outder
--outfile key.p12
428 Some
tools (reportedly web browsers
) have problems with that file
429 because it does not contain the CA certificate for the certificate.
430 To work around that problem in the tool
, you can use the
431 --load
-ca
-certificate parameter as follows
:
434 $ certtool
--load
-ca
-certificate ca.pem \
435 --load
-certificate cert.pem
--load
-privkey key.pem \
436 --to
-p12
--outder
--outfile key.p12
439 @subheading Diffie
-Hellman parameter generation
440 To generate parameters for Diffie
-Hellman key exchange
, use the command
:
442 $ certtool
--generate
-dh
-params
--outfile dh.pem
--sec
-param normal
445 @subheading Proxy certificate generation
446 Proxy certificate can be used to delegate your credential to a
447 temporary
, typically short
-lived
, certificate. To create one from the
448 previously created certificate
, first create a temporary key and then
449 generate a proxy certificate for it
, using the commands
:
452 $ certtool
--generate
-privkey
> proxy
-key.pem
453 $ certtool
--generate
-proxy
--load
-ca
-privkey key.pem \
454 --load
-privkey proxy
-key.pem
--load
-certificate cert.pem \
455 --outfile proxy
-cert.pem
458 @subheading Certificate revocation list generation
459 To create an empty Certificate Revocation
List (CRL
) do
:
462 $ certtool
--generate
-crl
--load
-ca
-privkey x509
-ca
-key.pem \
463 --load
-ca
-certificate x509
-ca.pem
466 To create a CRL that contains some revoked certificates
, place the
467 certificates in a file and use @code
{--load
-certificate
} as follows
:
470 $ certtool
--generate
-crl
--load
-ca
-privkey x509
-ca
-key.pem \
471 --load
-ca
-certificate x509
-ca.pem
--load
-certificate revoked
-certs.pem
474 To verify a Certificate Revocation
List (CRL
) do
:
477 $ certtool
--verify
-crl
--load
-ca
-certificate x509
-ca.pem
< crl.pem
487 @subheading Certtool
's template file format
488 A template file can be used to avoid the interactive questions of
489 certtool. Initially create a file named 'cert.cfg
' that contains the information
490 about the certificate. The template can be used as below:
493 $ certtool --generate-certificate cert.pem --load-privkey key.pem \
494 --template cert.cfg \
495 --load-ca-certificate ca-cert.pem --load-ca-privkey ca-key.pem
498 An example certtool template file that can be used to generate a certificate
499 request or a self signed certificate follows.
502 # X.509 Certificate options
506 # The organization of the subject.
507 organization = "Koko inc."
509 # The organizational unit of the subject.
