.SH NAME
\f[B]tss2_getcertificate\f[R](1) -
.SH SYNOPSIS
\f[B]tss2_getcertificate\f[R] [\f[I]OPTIONS\f[R]]
.SH SEE ALSO
\f[B]fapi-config(5)\f[R] to adjust Fapi parameters like the used
cryptographic profile and TCTI or directories for the Fapi metadata
storages.
.PP
\f[B]fapi-profile(5)\f[R] to determine the cryptographic algorithms and
parameters for all keys and operations of a specific TPM interaction
like the name hash algorithm, the asymmetric signature algorithm, scheme
and parameters and PCR bank selection.
.SH DESCRIPTION
\f[B]tss2_getcertificate\f[R](1) - This command returns the PEM encoded
X.509 certificate associated with the key at path.
.SH OPTIONS
These are the available options:
.IP \[bu] 2
\f[B]-f\f[R], \f[B]--force\f[R]:
.RS 2
.PP
Force overwriting the output file.
.RE
.IP \[bu] 2
\f[B]-p\f[R], \f[B]--path\f[R]=\f[I]STRING\f[R]:
.RS 2
.PP
The entity whose certificate is requested.
.RE
.IP \[bu] 2
\f[B]-o\f[R], \f[B]--x509certData\f[R]=\f[I]FILENAME\f[R] or \f[I]-\f[R]
(for stdout):
.RS 2
.PP
Returns the PEM encoded certificate.
If no certificate is stored, then an empty string is returned.

.SH COMMON OPTIONS
This collection of options are common to all tss2 programs and provide
information that many users may expect.
.IP \[bu] 2
\f[B]-h\f[R], \f[B]--help [man|no-man]\f[R]: Display the tools manpage.
By default, it attempts to invoke the manpager for the tool, however, on
failure will output a short tool summary.
This is the same behavior if the \[lq]man\[rq] option argument is
specified, however if explicit \[lq]man\[rq] is requested, the tool will
provide errors from man on stderr.
If the \[lq]no-man\[rq] option if specified, or the manpager fails, the
short options will be output to stdout.
.RS 2
.PP
To successfully use the manpages feature requires the manpages to be
installed or on \f[I]MANPATH\f[R], See \f[B]man\f[R](1) for more
details.
.RE
.IP \[bu] 2
\f[B]-v\f[R], \f[B]--version\f[R]: Display version information for this
tool, supported tctis and exit.
