.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.
If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.
Avoid warning from groff about undefined register 'F'.

Title "OPENSSL-REHASH 1ossl"
way too many mistakes in technical documents.
\fBc_rehash [-h] [-help] [-old] [-n] [-v] [-provider name] [-provider-path path] [-propquery propq] [directory] ...
\fBopenssl rehash scans directories and calculates a hash value of each .pem, .crt, .cer, or .crl file in the specified directory list and creates symbolic links for each file, where the name of the link is the hash value. (If the platform does not support symbolic links, a copy is made.) This command is useful as many programs that use OpenSSL require directories to be set up like this in order to find certificates.
If any directories are named on the command line, then those are processed in turn. If not, then the \s-1SSL_CERT_DIR\s0 environment variable is consulted; this should be a colon-separated list of directories, like the Unix \s-1PATH\s0 variable. If that is not set then the default directory (installation-specific but often /etc/ssl/certs) is processed.
In order for a directory to be processed, the user must have write permissions on that directory, otherwise an error will be generated.
The links created are of the form \s-1HHHHHHHH.D\s0, where each H is a hexadecimal character and D is a single decimal digit. When a directory is processed, all links in it that have a name in that syntax are first removed, even if they are being used for some other purpose. To skip the removal step, use the -n flag. Hashes for \s-1CRL\s0's look similar except the letter r appears after the period, like this: \s-1HHHHHHHH.\s0rD.
Multiple objects may have the same hash; they will be indicated by incrementing the D value. Duplicates are found by comparing the full \s-1SHA-1\s0 fingerprint. A warning will be displayed if a duplicate is found.
A warning will also be displayed if there are files that cannot be parsed as either a certificate or a \s-1CRL\s0 or if more than one such object appears in the file.
.Vb 2 $OPENSSL x509 -hash -fingerprint -noout -in FILENAME $OPENSSL crl -hash -fingerprint -noout -in FILENAME .Ve
where \s-1FILENAME\s0 is the filename. It must output the hash of the file on the first line, and the fingerprint on the second, optionally prefixed with some text and an equals sign.
