=head1 DESCRIPTION
|
|
|
|
This command processes public or private keys. They can be
|
|
converted between various forms and their components printed.

|
|
=head2 General options
|
|

=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.

|
{- $OpenSSL::safe::opt_engine_item -}
|
|
|
|
{- $OpenSSL::safe::opt_provider_item -}
|
|
|
|
=item B<-check>
|
|
|
|
This option checks the consistency of a key pair for both public and private
|
|
components.
|
|
|
|
=item B<-pubcheck>
|
|
|
|
This option checks the correctness of either a public key
|
|
or the public component of a key pair.

=head2 Input options
|
|
|
|
=over 4
|
|
|
|
=item B<-in> I<filename>|I<uri>
|
|
|
|
This specifies the input file to read a key from
|
|
or standard input if this option is not specified.
|
|
|
|
If the key input is encrypted and B<-passin> is not given
|
|
a pass phrase will be prompted for.
|
|
|
|
=item B<-inform> B<DER>|B<PEM>|B<P12>|B<ENGINE>
|
|
|
|
The key input format; unspecified by default.
|
|
See L<openssl-format-options(1)> for details.
|
|
|
|
=item B<-passin> I<arg>
|
|
|
|
The password source for the key input.
|
|
|
|
For more information about the format of B<arg>
|
|
see L<openssl-passphrase-options(1)>.
|
|
|
|
=item B<-pubin>
|
|
|
|
By default a private key is read from the input.
|
|
With this option a public key is read instead.
|
|
If the input contains no public key but a private key, its public part is used.
|
|
|

=back
|
|
|
|
=head2 Output options
|
|
|
|
=over 4
|
|
|
|
=item B<-out> I<filename>
|
|
|
|
This specifies the output file to save the encoded and/or text output of key
|
|
or standard output if this option is not specified.
|
|
The output filename can be the same as the input filename,
|
|
which leads to replacing the file contents.
|
|
Note that file I/O is not atomic. The output file is truncated and then written.
|
|
|
|
If any cipher option is set but no B<-passout> is given
|
|
then a pass phrase will be prompted for.
|
|
When password input is interrupted, the output file is not touched.
|
|
|
|
=item B<-outform> B<DER>|B<PEM>
|
|
|
|
The key output format; the default is B<PEM>.
|
|
See L<openssl-format-options(1)> for details.
|
|
|
|
=item B<-I<cipher>>
|
|
|
|
Encrypt the PEM encoded private key with the supplied cipher. Any algorithm
|
|
name accepted by EVP_get_cipherbyname() is acceptable such as B<aes128>.
|
|
Encryption is not supported for DER output.
|
|
|
|
=item B<-passout> I<arg>
|
|
|
|
The password source for the output file.
|
|
|
|
For more information about the format of B<arg>
|
|
see L<openssl-passphrase-options(1)>.
|
|
|
|
=item B<-traditional>
|
|
|
|
Normally a private key is written using standard format: this is PKCS#8 form
|
|
with the appropriate encryption algorithm (if any). If the B<-traditional>
|
|
option is specified then the older "traditional" format is used instead.
|
|
|
|
=item B<-pubout>
|
|
|
|
By default the private and public key is output;
|
|
this option restricts the output to the public components.
|
|
This option is automatically set if the input is a public key.
|
|
|
|
When combined with B<-text>, this is equivalent to B<-text_pub>.
|
|
|
|
=item B<-noout>
|
|
|
|
Do not output the key in encoded form.
|
|
|
|
=item B<-text>
|
|
|
|
Output the various key components in plain text
|
|
(possibly in addition to the PEM encoded form).
|
|
This cannot be combined with encoded output in DER format.
|
|
|
|
=item B<-text_pub>
|
|
|
|
Output in text form only the public key components (also for private keys).
|
|
This cannot be combined with encoded output in DER format.
|
|
|
|
=item B<-ec_conv_form> I<arg>
|
|
|
|
This option only applies to elliptic-curve based keys.
|
|
|
|
This specifies how the points on the elliptic curve are converted
|
|
into octet strings. Possible values are: B<compressed> (the default
|
|
value), B<uncompressed> and B<hybrid>. For more information regarding
|
|
the point conversion forms please read the X9.62 standard.
|
|
B<Note> Due to patent issues the B<compressed> option is disabled
|
|
by default for binary curves and can be enabled by defining
|
|
the preprocessor macro B<OPENSSL_EC_BIN_PT_COMP> at compile time.
|
|
|
|
=item B<-ec_param_enc> I<arg>
|
|
|
|
This option only applies to elliptic curve based public and private keys.
|
|
|
|
This specifies how the elliptic curve parameters are encoded.
|
|
Possible value are: B<named_curve>, i.e. the ec parameters are
|
|
specified by an OID, or B<explicit> where the ec parameters are
|
|
explicitly given (see RFC 3279 for the definition of the
|
|
EC parameters structures). The default value is B<named_curve>.
|
|
B<Note> the B<implicitlyCA> alternative, as specified in RFC 3279,
|
|
is currently not implemented in OpenSSL.

=head1 EXAMPLES
|
|
|
|
To remove the pass phrase on a private key:
|
|
|
|
openssl pkey -in key.pem -out keyout.pem
|
|
|
|
To encrypt a private key using triple DES:
|
|
|
|
openssl pkey -in key.pem -des3 -out keyout.pem
|
|
|
|
To convert a private key from PEM to DER format:
|
|
|
|
openssl pkey -in key.pem -outform DER -out keyout.der
|
|
|
|
To print out the components of a private key to standard output:
|
|
|
|
openssl pkey -in key.pem -text -noout
|
|
|
|
To print out the public components of a private key to standard output:
|
|
|
|
openssl pkey -in key.pem -text_pub -noout
|
|
|
|
To just output the public part of a private key:
|
|
|
|
openssl pkey -in key.pem -pubout -out pubkey.pem
|
|
|
|
To change the EC parameters encoding to B<explicit>:
|
|
|
|
openssl pkey -in key.pem -ec_param_enc explicit -out keyout.pem
|
|
|
|
To change the EC point conversion form to B<compressed>:
|
|
|
|
openssl pkey -in key.pem -ec_conv_form compressed -out keyout.pem
