+=head1 DESCRIPTION
+
+The B<genpkey> command generates a private key.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-out filename>
+
+the output filename. If this argument is not specified then standard output is
+used.  
+
+=item B<-outform DER|PEM>
+
+This specifies the output format DER or PEM.
+
+=item B<-pass arg>
+
+the output file password source. For more information about the format of B<arg>
+see the B<PASS PHRASE ARGUMENTS> section in L<openssl(1)|openssl(1)>.
+
+=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>.
+
+=item B<-engine id>
+
+specifying an engine (by it's unique B<id> string) will cause B<req>
+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.
+
+=item B<-algorithm alg>
+
+public key algorithm to use such as RSA, DSA or DH.
+
+=item B<-pkeyopt opt:value>
+
+set the public key algorithm option B<opt> to B<value>. The precise set of
+options supported depends on the public key algorithm used and its
+implementation. See B<KEY GENERATION OPTIONS> below for more details.
+
+=item B<-genparam>
+
+generate a set of parameters instead of a private key.
+
+=item B<-paramfile filename>
+
+Some public key algorithms generate a private key based on a set of parameters.
+They can be supplied using this option. If this option is used the public
+key algorithm used is determined by the parameters.
+

+
+=head1 KEY GENERATION OPTIONS
+
+The options supported by each algorith and indeed each implementation of an
+algorithm can vary. The options for the OpenSSL implementations are detailed
+below.
+
+=head1 RSA KEY GENERATION OPTIONS
+
+=over 4
+
+=item B<rsa_keygen_bits:numbits>
+
+The number of bits in the generated key. If not specified 1024 is used.
+
+=item B<rsa_keygen_pubexp:value>
+
+The RSA public exponent value. This can be a large decimal or
+hexadecimal value if preceded by B<0x>. Default value is 65537.
+
+=back
+
+=head1 DSA PARAMETER GENERATION OPTIONS
+
+=over 4
+
+=item B<dsa_paramgen_bits:numbits>
+
+The number of bits in the generated parameters. If not specified 1024 is used.
+
+=head1 DH PARAMETER GENERATION OPTIONS
+
+=over 4
+
+=item B<dh_paramgen_prime_len:numbits>
+
+The number of bits in the prime parameter B<p>.
+
+=item B<dh_paramgen_generator:value>
+
+The value to use for the generator B<g>.
+
+=back
+
+=head1 EC PARAMETER GENERATION OPTIONS
+
+=over 4
+
+=item B<ec_paramgen_curve:curve>
+
+the EC curve to use.
+
+=back
+
+=head1 NOTES
+
+The use of the genpkey program is encouraged over the algorithm specific
+utilities because additional algorithm options and ENGINE provided algorithms
+can be used.
+
+=head1 EXAMPLES
+
+Generate an RSA private key using default parameters:
+
+ openssl genpkey -algoritm RSA -out key.pem 
+
+Encrypt output private key using 128 bit AES and the passphrase "hello":
+
+ openssl genpkey -algoritm RSA -out key.pem -aes-128-cbc -pass pass:hello
+
+Generate a 2048 bit RSA key using 3 as the public exponent:
+
+ openssl genpkey -algoritm RSA -out key.pem -pkeyopt rsa_keygen_bits:2048 \
+ 						-pkeyopt rsa_keygen_pubexp:3
+
+Generate 1024 bit DSA parameters:
+
+ openssl genpkey -genparam -algorithm DSA -out dsap.pem \
+						-pkeyopt dsa_paramgen_bits:1024
+
+Generate DSA key from parameters:
+
+ openssl genpkey -paramfile dsap.pem -out dsakey.pem 
+
+Generate 1024 bit DH parameters:
+
+ openssl genpkey -genparam -algorithm DH -out dhp.pem \
+					-pkeyopt dh_paramgen_prime_len:1024
+
+Generate DH key from parameters:
+
+ openssl genpkey -paramfile dhp.pem -out dhkey.pem

+=head1 DESCRIPTION
+
+The B<pkey> command processes public or private keys. They can be converted
+between various forms and their components printed out.
+
+=head1 COMMAND OPTIONS
+
+=over 4
+
+=item B<-inform DER|PEM>
+
+This specifies the input format DER or PEM.
+
+=item B<-outform DER|PEM>
+
+This specifies the output format, the options have the same meaning as the 
+B<-inform> option.
+
+=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.
+
+=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<openssl(1)|openssl(1)>.
+
+=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.
+
+=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<openssl(1)|openssl(1)>.
+
+=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>.
+
+=item B<-text>
+
+prints out the various public or private key components in
+plain text in addition to the encoded version. 
+
+=item B<-text_pub>
+
+print out only public key components even if a private key is being processed.
+
+=item B<-noout>
+
+do not output the encoded version of the key.
+
+=item B<-pubin>
+
+by default a private key is read from the input file: with this
+option a public key is read instead.
+
+=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.
+
+=item B<-engine id>
+
+specifying an engine (by it's unique B<id> string) will cause B<req>
+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.
+

+
+=head1 EXAMPLES
+
+To remove the pass phrase on an RSA 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
