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"

|
|
\&\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\-keyform arg\fR" 4
|
|
.IX Item "-keyform arg"
|
|
Specifies the key format to sign digest with. Only \s-1PEM\s0 and \s-1ENGINE\s0
|
|
formats are supported by the \fBdgst\fR command.
|
|
.IP "\fB\-engine id\fR" 4
|
|
.IX Item "-engine id"
|
|
Use engine \fBid\fR for operations (including private key storage).
|
|
This engine is not used as source for digest algorithms, unless it is
|
|
also specified in the configuration file.
|
|
.IP "\fB\-sigopt nm:v\fR" 4
|
|
.IX Item "-sigopt nm:v"
|
|
Pass options to the signature algorithm during sign or verify operations.
|
|
Names and values of these options are algorithm-specific.
|
|
.IP "\fB\-passin arg\fR" 4
|
|
.IX Item "-passin arg"
|
|
the private key password source. For more information about the format of \fBarg\fR
|
|
see the \fB\s-1PASS\s0 \s-1PHRASE\s0 \s-1ARGUMENTS\s0\fR section in \fIopenssl\fR\|(1).
|
|
.IP "\fB\-verify filename\fR" 4
|
|
.IX Item "-verify filename"
|
|
verify the signature using 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 private key in \*(L"filename\*(R".
|
|
.IP "\fB\-signature filename\fR" 4
|
|
.IX Item "-signature filename"
|
|
the actual signature to verify.
|
|
.IP "\fB\-hmac key\fR" 4
|
|
.IX Item "-hmac key"
|
|
create a hashed \s-1MAC\s0 using \*(L"key\*(R".
|
|
.IP "\fB\-mac alg\fR" 4
|
|
.IX Item "-mac alg"
|
|
create \s-1MAC\s0 (keyed Message Authentication Code). The most popular \s-1MAC\s0
|
|
algorithm is \s-1HMAC\s0 (hash-based \s-1MAC\s0), but there are other \s-1MAC\s0 algorithms
|
|
which are not based on hash, for instance \fBgost-mac\fR algorithm,
|
|
supported by \fBccgost\fR engine. \s-1MAC\s0 keys and other options should be set
|
|
via \fB\-macopt\fR parameter.
|
|
.IP "\fB\-macopt nm:v\fR" 4
|
|
.IX Item "-macopt nm:v"
|
|
Passes options to \s-1MAC\s0 algorithm, specified by \fB\-mac\fR key.
|
|
Following options are supported by both by \fB\s-1HMAC\s0\fR and \fBgost-mac\fR:
|
|
.RS 4
|
|
.IP "\fBkey:string\fR" 8
|
|
.IX Item "key:string"
|
|
Specifies \s-1MAC\s0 key as alphnumeric string (use if key contain printable
|
|
characters only). String length must conform to any restrictions of
|
|
the \s-1MAC\s0 algorithm for example exactly 32 chars for gost-mac.
|
|
.IP "\fBhexkey:string\fR" 8
|
|
.IX Item "hexkey:string"
|
|
Specifies \s-1MAC\s0 key in hexadecimal form (two hex digits per byte).
|
|
Key length must conform to any restrictions of the \s-1MAC\s0 algorithm
|
|
for example exactly 32 chars for gost-mac.

.RS 4
|
|
.RE
|
|
.IP "\fB\-rand file(s)\fR" 4
|
|
.IX Item "-rand file(s)"
|
|
a file or files containing random data used to seed the random number
|
|
generator, or an \s-1EGD\s0 socket (see \fIRAND_egd\fR\|(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.
