in a table. Doesn't do too much yet.
Make the -<digestname> options in 'x509' affect all relevant
options.
Change the name of the 'notrust' options to 'reject' as this
causes less confusion and is a better description of the
effect.
A few constification changes.
Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
+ *) Fixes and enhancements to the 'x509' utility. It allowed a message
+ digest to be passed on the command line but it only used this
+ parameter when signing a certificate. Modified so all relevant
+ operations are affected by the digest parameter including the
+ -fingerprint and -x509toreq options. Also -x509toreq choked if a
+ DSA key was used because it didn't fix the digest.
+ [Steve Henson]
+
*) Very preliminary certificate chain verify code. Currently just tests
the untrusted certificates for consistency with the verify purpose
(which is set when the X509_STORE_CTX structure is set up) and checks
reject chains with invalid extensions whereas before it made no checks
at all.
- Still needs some trust checking code.
+ Preliminary untested trust code.
Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
which should be used for version portability: especially since the

=item B<-fingerprint>
-prints out the MD5 digest of the whole certificate.
+prints out the digest of the DER encoded version of the whole certificate.
=item B<-C>
clears all the permitted or trusted uses of the certificate.
-=item B<-clrnotrust>

clears all the prohibited or untrusted uses of the certificate.

(SSL server use) email (S/MIME email) and objsign (Object signing).
-=item B<-addnotrust arg>
+=item B<-addreject arg>
adds a prohibited use. It accepts the same values as the B<-addtrust>
option.
it will contain the serial number "01". Normally if the B<-CA> option is
specified and the serial number file does not exist it is an error.

-the digest to sign with. It affects all commands that sign a certificate
-or request.

=item B<-extfile filename>
file containing certificate extensions to use. If not specified then
openssl x509 -in cert.pem -noout -text
-Displa the certificate serial number:
+Display the certificate serial number:
openssl x509 -in cert.pem -noout -serial
+Display the certificate MD5 fingerprint:
+
+ openssl x509 -in cert.pem -noout -fingerprint
+
+Display the certificate SHA1 fingerprint:
+
+ openssl x509 -sha1 -in cert.pem -noout -fingerprint
Convert a certificate from PEM to DER format:
-----BEGIN X509 CERTIFICATE----
-----END X509 CERTIFICATE----
+Trusted certificates have the lines
+
+ -----BEGIN TRUSTED CERTIFICATE----
+ -----END TRUSTED CERTIFICATE----
+
+The B<-fingerprint> option takes the digest of the DER encoded certificate.
+This is commonly called a "fingerprint". Because of the nature of message
+digests the fingerprint of a certificate is unique to that certificate and
+two certificates with the same fingerprint can be considered to be the same.
+
+The Netscape fingerprint uses MD5 whereas MSIE uses SHA1.

=head1 BUGS
The way DNs are printed is in a "historical SSLeay" format which doesn't
wrong private key or using inconsistent options in some cases: these should
be checked.
-There should be options to explicitly set such things are start and end
+There should be options to explicitly set such things as start and end
dates rather than an offset from the current time.
The code to implement the verify behaviour described in the B<TRUST SETTINGS>
than the current behaviour. It is hoped that it will represent reality in
OpenSSL 0.9.5 and later.
