=head1 DESCRIPTION
|
||
|
||
The B<pkey> command processes public or private keys. They can be converted
|
||
between various forms and their components printed out.
|
||
|
||
pkey指令处理公钥或者私钥。
|
||
它们可以在各种形式之间进行转换，并将其组件打印出来。
|
||
|
||
=head1 OPTIONS
|
||
|
||
=over 4
|
||
|
||
=item B<-help>
|
||
|
||
Print out a usage message.
|
||
|
||
打印使用信息。
|
||
|
||
=item B<-inform DER|PEM>
|
||
|
||
This specifies the input format DER or PEM.
|
||
|
||
该选项指出了输入格式是DER还是PEM。
|
||
|
||
=item B<-outform DER|PEM>
|
||
|
||
This specifies the output format, the options have the same meaning as the
|
||
B<-inform> option.
|
||
|
||
该选项指出了输出格式，与-inform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.
|
||
|
||
如果该选项没有被指定，则指定从密钥中读取输入文件名或者标准输入。
|
||
如果密钥被加密，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)>.
|
||
|
||
输入文件的密码来源。有关arg格式的更多信息，请参阅gmssl（1）中的PASS PHRASE ARGUMENTS部分。
|
||
|
||
=item B<-out filename>
|
||
|
||
This specifies the output filename to write a key to or standard output if this
|
||
option 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.
|
||
|
||
如果未指定此选项，则指定将密钥写入或输出的输出文件名。 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 password>
|
||
|
||
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)>.
|
||
|
||
输出文件的密码来源。有关arg格式的更多信息请参阅gmssl(1)中的PASS PHARSE ARGUMENTS部分。
|
||
|
||
=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.
|
||
|
||
通常使用标准格式写入私钥：这是具有适当加密算法（如果有的话）的PKCS＃8表单。
|
||
如果指定了-traditional选项，则使用较旧的“traditional”格式。
|
||
|
||
=item B<-cipher>
|
||
|
||
These options encrypt the private key with the supplied cipher. Any algorithm
|
||
name accepted by EVP_get_cipherbyname() is acceptable such as B<des3>.
|
||
|
||
这些选项使用提供的密码加密私钥。 EVP_get_cipherbyname（）接受的任何算法名称都可以接受，如des3。
|
||
|
||
=item B<-text>
|
||
|
||
prints out the various public or private key components in
|
||
plain text in addition to the encoded version.
|
||
|
||
除了编码版本之外，以纯文本形式打印各种公共或私人密钥组件。
|
||
|
||
=item B<-text_pub>
|
||
|
||
print out only public key components even if a private key is being processed.
|
||
|
||
即使正在处理私钥，也打印公钥组件。
|
||
|
||
=item B<-noout>
|
||
|
||
do not output the encoded version of the key.
|
||
|
||
不打印出密钥的编码版本信息。
|
||
|
||
=item B<-pubin>
|
||
|
||
by default a private key is read from the input file: with this
|
||
option a public key is read instead.
|
||
|
||
默认从输入文件读取一个私钥：使用该选项后则变为读取一个公钥。
|
||
|
||
=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.
|
||
|
||
|
||
默认是输出一个私钥：使用该选项后则变为输出一个公钥。如果输入是公钥则该选项会自动设置。
|
||
|
||
=item B<-engine id>
|
||
|
||
specifying an engine (by its unique B<id> string) will cause B<pkey>
|
||
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.
|
||
|
||
指定要使用的硬件引擎。指定一个引擎（通过其唯一的id字符串）将导致pkey尝试获取对指定引擎的功能引用
|
||
，从而如果需要的话初始化它。 然后，引擎将被设置为所有可用算法的默认值。

=head1 EXAMPLES
|
||
|
||
To remove the pass phrase on an RSA private key:
|
||
|
||
gmssl pkey -in key.pem -out keyout.pem
|
||
|
||
To encrypt a private key using triple DES:
|
||
|
||
gmssl pkey -in key.pem -des3 -out keyout.pem
|
||
|
||
To convert a private key from PEM to DER format:
|
||
|
||
gmssl pkey -in key.pem -outform DER -out keyout.der
|
||
|
||
To print out the components of a private key to standard output:
|
||
|
||
gmssl pkey -in key.pem -text -noout
|
||
|
||
To print out the public components of a private key to standard output:
|
||
|
||
gmssl pkey -in key.pem -text_pub -noout
|
||
|
||
To just output the public part of a private key:
|
||
|
||
gmssl pkey -in key.pem -pubout -out pubkey.pem
