.SH "OPTIONS"
.
.TP
.B "\-h, \-\-help"
Print usage information with a summary of the available options.
.TP
.BI "\-v, \-\-debug " level
Set debug level, default: 1.
.TP
.BI "\-+, \-\-options " file
Read command line options from \fIfile\fR.
.TP
.BI "\-i, \-\-in " file
Input file. If not given the input is read from \fISTDIN\fR.
.TP

\fIpub\fR (public key), \fIpkcs10\fR (PKCS#10 certificate request),
\fIx509\fR (X.509 certificate), defaults to \fIpriv\fR.
.TP
.BI "\-I, \-\-id " id-type
Type of identifier. One of \fIall\fR (all identifiers), \fIspk\fR (SHA-1 hash
of subjectPublicKey), \fIspki\fR (SHA-1 hash of subjectPublicKeyInfo), defaults
to \fIall\fR.
.TP
.BI "\-f, \-\-format " format
Output format. One of \fIpretty\fR (user-readable output), \fIhex\fR
(hexadecimal encoding), \fIbase64\fR (Base64 encoding), \fIbin\fR (raw binary
data), defaults to \fIpretty\fR.
