=head1 DESCRIPTION
|
|
|
|
The B<ec> command processes EC keys. They can be converted between various
|
|
forms and their components printed out. B<Note> GmSSL uses the
|
|
private key format specified in 'SEC 1: Elliptic Curve Cryptography'
|
|
(http://www.secg.org/). To convert an GmSSL EC private key into the
|
|
PKCS#8 private key format use the B<pkcs8> command.
|
|
|
|
ec命令处理EC密钥。 它们可以在各种形式之间进行转换，并将其组件打印出来。 注意GmSSL使用“SEC 1：椭圆曲线加密”（http://www.secg.org/）中指定的私钥格式。 要将GmSSL EC私钥转换为PKCS＃8私钥格式，请使用pkcs8命令。

|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.
|
|
|
|
输出使用信息。
|
|
|
|
=item B<-inform DER|PEM>
|
|
|
|
This specifies the input format. The B<DER> option with a private key uses
|
|
an ASN.1 DER encoded SEC1 private key. When used with a public key it
|
|
uses the SubjectPublicKeyInfo structure as specified in RFC 3280.
|
|
The B<PEM> form is the default format: it consists of the B<DER> format base64
|
|
encoded with additional header and footer lines. In the case of a private key
|
|
PKCS#8 format is also accepted.
|
|
|
|
该指令指出了输入文件格式。DER选项是一个私钥，它用ASN.1 DER编码的SEC1私钥文件。当为公钥时，用RFC3280指定的SubjectPublicKeyInfo结构。默认的是PEM格式，它也接受PKCS#8格式的私钥。
|
|
|
|
=item B<-outform DER|PEM>
|
|
|
|
This specifies the output format, the options have the same meaning as the
|
|
B<-inform> option.
|
|
|
|
该指令指出了输出格式。与-inform指令意义相同。
|
|
|
|
=item B<-in filename>
|
|
|
|
This specifies the input filename to read a key from or standard input if this
|
|
option is not specified. If the key is encrypted a pass phrase will be
|
|
prompted for.
|
|
|
|
如果未指定此选项，则指定从或从标准输入读取密钥的输入文件名。 如果密钥加密，将提示输入密码。
|
|
|
|
=item B<-passin arg>
|
|
|
|
the input file password source. For more information about the format of B<arg>
|
|
see the B<PASS PHRASE ARGUMENTS> section in L<gmssl(1)>.
|
|
|
|
指定私钥包含口令存放方式。
|
|
|
|
=item B<-out filename>
|
|
|
|
This specifies the output filename to write a key to or standard output by
|
|
is not specified. If any encryption options are set then a pass phrase will be
|
|
prompted for. The output filename should B<not> be the same as the input
|
|
filename.
|
|
|
|
这指定了未指定要写入或输出的标准输出的输出文件名。 如果设置了任何加密选项，则会提示输入密码。 输出文件名不能与输入文件名相同。
|
|
|
|
=item B<-passout arg>
|
|
|
|
the output file password source. For more information about the format of B<arg>
|
|
see the B<PASS PHRASE ARGUMENTS> section in L<gmssl(1)>.
|
|
|
|
输出文件口令保护存放方式。
|
|
|
|
=item B<-des|-des3|-sms4>
|
|
|
|
These options encrypt the private key with the DES, triple DES, SMS4 or
|
|
any other cipher supported by GmSSL before outputting it. A pass phrase is
|
|
prompted for.
|
|
If none of these options is specified the key is written in plain text. This
|
|
means that using the B<ec> utility to read in an encrypted key with no
|
|
encryption option can be used to remove the pass phrase from a key, or by
|
|
setting the encryption options it can be use to add or change the pass phrase.
|
|
These options can only be used with PEM format output files.
|
|
|
|
这些选项在输出之前，使用DES，三重DES，SMS4或GmSSL支持的任何其他密码加密私钥。 提示通行短语。 如果没有指定这些选项，则键将以纯文本形式写入。 这意味着使用ec实用程序读取加密密钥，无加密选项可用于从密钥中删除密码短语，或通过设置可用于添加或更改密码短语的加密选项。 这些选项只能用于PEM格式的输出文件。
|
|
|
|
=item B<-text>
|
|
|
|
prints out the public, private key components and parameters.
|
|
|
|
输出公钥和私钥的组成参数。
|
|
|
|
=item B<-noout>
|
|
|
|
this option prevents output of the encoded version of the key.
|
|
|
|
不输出密钥信息。
|
|
|
|
=item B<-modulus>
|
|
|
|
this option prints out the value of the public key component of the key.
|
|
|
|
该选项输出公钥组件值。
|
|
|
|
=item B<-pubin>
|
|
|
|
by default a private key is read from the input file: with this option a
|
|
public key is read instead.
|
|
|
|
默认读取为私钥，输入该指令后，从输入文件中读取公钥。
|
|
|
|
=item B<-pubout>
|
|
|
|
by default a private key is output. With this option a public
|
|
key will be output instead. This option is automatically set if the input is
|
|
a public key.
|
|
|
|
输入该指令后，公钥值到输出文件中。默认保存私钥到输出文件。如果输入是公钥该选项将自动设置。
|
|
|
|
=item B<-conv_form>
|
|
|
|
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.
|
|
|
|
这指定椭圆曲线上的点如何转换为八位字节串。 可能的值有：压缩（默认值），未压缩和混合。 有关点转换表单的更多信息，请阅读X9.62标准。 注意由于专利问题，压缩选项默认情况下禁用二进制曲线，并且可以通过在编译时定义预处理器宏OPENSSL_EC_BIN_PT_COMP来启用。
|
|
|
|
=item B<-param_enc arg>
|
|
|
|
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 GmSSL.
|
|
|
|
这指定椭圆曲线参数的编码方式。 可能的值为：named_curve，即ec参数由OID指定，或显式指定ec参数（参见RFC 3279以了解EC参数结构的定义）。 默认值为named_curve。 注意，如RFC 3279所述，implicitlyCA替代方案目前尚未在GmSSL中实现
|
|
|
|
=item B<-no_public>
|
|
|
|
This option omits the public key components from the private key output.
|
|
|
|
该指令省略了私钥输出中的公钥组件。
|
|
|
|
=item B<-check>
|
|
|
|
this option checks the consistency of an EC private or public key.
|
|
|
|
该指令检查了EC私钥或公钥的一致性。
|
|
|
|
=item B<-engine id>
|
|
|
|
specifying an engine (by its unique B<id> string) will cause B<ec>
|
|
to attempt to obtain a functional reference to the specified engine,
|
|
thus initialising it if needed. The engine will then be set as the default
|
|
for all available algorithms.
|
|
|
|
指定引擎。

=head1 NOTES
|
|
|
|
The PEM private key format uses the header and footer lines:
|
|
|
|
-----BEGIN EC PRIVATE KEY-----
|
|
-----END EC PRIVATE KEY-----
|
|
|
|
The PEM public key format uses the header and footer lines:
|
|
|
|
-----BEGIN PUBLIC KEY-----
|
|
-----END PUBLIC KEY-----
|
|
|
|
=head1 EXAMPLES
|
|
|
|
To encrypt a private key using triple DES:
|
|
|
|
gmssl ec -in key.pem -des3 -out keyout.pem
|
|
|
|
To convert a private key from PEM to DER format:
|
|
|
|
gmssl ec -in key.pem -outform DER -out keyout.der
|
|
|
|
To print out the components of a private key to standard output:
|
|
|
|
gmssl ec -in key.pem -text -noout
|
|
|
|
To just output the public part of a private key:
|
|
|
|
gmssl ec -in key.pem -pubout -out pubkey.pem
|
|
|
|
To change the parameters encoding to B<explicit>:
|
|
|
|
gmssl ec -in key.pem -param_enc explicit -out keyout.pem
|
|
|
|
To change the point conversion form to B<compressed>:
|
|
|
|
gmssl ec -in key.pem -conv_form compressed -out keyout.pem
