They can be converted between various -forms and their components printed out. B<Note> this command uses the -traditional SSLeay compatible format for private key encryption: newer -applications should use the more secure PKCS#8 format using the B<pkcs8> -utility. - -=head1 COMMAND OPTIONS - -=over 4 - -=item B<-inform DER|NET|PEM> - -This specifies the input format. The B<DER> option uses an ASN1 DER encoded -form compatible with the PKCS#1 RSAPrivateKey or SubjectPublicKeyInfo format. -The B<PEM> form is the default format: it consists of the B<DER> format base64 -encoded with additional header and footer lines. On input PKCS#8 format private -keys are also accepted. The B<NET> form is a format is described in the B<NOTES> -section. - -=item B<-outform DER|NET|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<-sgckey> - -use the modified NET algorithm used with some versions of Microsoft IIS and SGC -keys. - -=item B<-des|-des3|-idea> - -These options encrypt the private key with the DES, triple DES, or the -IDEA ciphers respectively 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<rsa> 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. - -=item B<-text> - -prints out the various public or private key components in -plain text in addition to the encoded version. - -=item B<-noout> - -this option prevents output of the encoded version of the key. - -=item B<-modulus> - -this option prints out the value of the modulus of the key. - -=item B<-check> - -this option checks the consistency of an RSA private 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. - -=back - -=head1 NOTES - -The PEM private key format uses the header and footer lines: - - -----BEGIN RSA PRIVATE KEY----- - -----END RSA PRIVATE KEY----- - -The PEM public key format uses the header and footer lines: - - -----BEGIN PUBLIC KEY----- - -----END PUBLIC KEY----- - -The B<NET> form is a format compatible with older Netscape servers -and Microsoft IIS .key files, this uses unsalted RC4 for its encryption. -It is not very secure and so should only be used when necessary. - -Some newer version of IIS have additional data in the exported .key -files. To use these with the utility, view the file with a binary editor -and look for the string "private-key", then trace back to the byte -sequence 0x30, 0x82 (this is an ASN1 SEQUENCE). Copy all the data -from this point onwards to another file and use that as the input -to the B<rsa> utility with the B<-inform NET> option. If you get -an error after entering the password try the B<-sgckey> option. - -=head1 EXAMPLES - -To remove the pass phrase on an RSA private key: - - openssl rsa -in key.pem -out keyout.pem - -To encrypt a private key using triple DES: - - openssl rsa -in key.pem -des3 -out keyout.pem - -To convert a private key from PEM to DER format: - - openssl rsa -in key.pem -outform DER -out keyout.der - -To print out the components of a private key to standard output: - - openssl rsa -in key.pem -text -noout - -To just output the public part of a private key: - - openssl rsa -in key.pem -pubout -out pubkey.pem - -=head1 BUGS - -The command line password arguments don't currently work with -B<NET> format. - -There should be an option that automatically handles .key files, -without having to manually edit them. - -=head1 SEE ALSO - -L<pkcs8(1)|pkcs8(1)>, L<dsa(1)|dsa(1)>, L<genrsa(1)|genrsa(1)>, -L<gendsa(1)|gendsa(1)> - -=cut |
