+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The digest functions output the message digest of a supplied file or files
+in hexadecimal form. They can also be used for digital signing and verification.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.Ip "\fB\-c\fR" 4
+.IX Item "-c"
+print out the digest in two digit groups separated by colons, only relevant if
+\&\fBhex\fR format output is used.
+.Ip "\fB\-d\fR" 4
+.IX Item "-d"
+print out \s-1BIO\s0 debugging information.
+.Ip "\fB\-hex\fR" 4
+.IX Item "-hex"
+digest is to be output as a hex dump. This is the default case for a \*(L"normal\*(R"
+digest as opposed to a digital signature.
+.Ip "\fB\-binary\fR" 4
+.IX Item "-binary"
+output the digest or signature in binary form.
+.Ip "\fB\-out filename\fR" 4
+.IX Item "-out filename"
+filename to output to, or standard output by default.
+.Ip "\fB\-sign filename\fR" 4
+.IX Item "-sign filename"
+digitally sign the digest using the private key in \*(L"filename\*(R".
+.Ip "\fB\-verify filename\fR" 4
+.IX Item "-verify filename"
+verify the signature using the the public key in \*(L"filename\*(R".
+The output is either \*(L"Verification \s-1OK\s0\*(R" or \*(L"Verification Failure\*(R".
+.Ip "\fB\-prverify filename\fR" 4
+.IX Item "-prverify filename"
+verify the signature using the the private key in \*(L"filename\*(R".
+.Ip "\fB\-signature filename\fR" 4
+.IX Item "-signature filename"
+the actual signature to verify.
+.Ip "\fB\-rand \f(BIfile\fB\|(s)\fR" 4
+.IX Item "-rand file"
+a file or files containing random data used to seed the random number
+generator, or an \s-1EGD\s0 socket (see RAND_egd(3)).
+Multiple files can be specified separated by a OS-dependent character.
+The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for
+all others.
+.Ip "\fBfile...\fR" 4
+.IX Item "file..."
+file or files to digest. If no files are specified then standard input is
+used.
+.SH "NOTES"
+.IX Header "NOTES"
+The digest of choice for all new applications is \s-1SHA1\s0. Other digests are
+however still widely used.
+.PP
+If you wish to sign or verify data using the \s-1DSA\s0 algorithm then the dss1
+digest must be used.
+.PP
+A source of random numbers is required for certain signing algorithms, in
+particular \s-1DSA\s0.
+.PP
+The signing and verify options should only be used if a single file is
+being signed or verified.
