They can be converted between various forms and their components printed out. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-help\fR" 4 .IX Item "-help" Print out a usage message. .IP "\fB\-inform DER|PEM\fR" 4 .IX Item "-inform DER|PEM" This specifies the input format \s-1DER\s0 or \s-1PEM.\s0 The default format is \s-1PEM.\s0 .IP "\fB\-outform DER|PEM\fR" 4 .IX Item "-outform DER|PEM" This specifies the output format, the options have the same meaning and default as the \fB\-inform\fR option. .IP "\fB\-in filename\fR" 4 .IX Item "-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. .IP "\fB\-passin arg\fR" 4 .IX Item "-passin arg" The input file password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-out filename\fR" 4 .IX Item "-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 \fBnot\fR be the same as the input filename. .IP "\fB\-passout password\fR" 4 .IX Item "-passout password" The output file password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-traditional\fR" 4 .IX Item "-traditional" Normally a private key is written using standard format: this is PKCS#8 form with the appropriate encryption algorithm (if any). If the \fB\-traditional\fR option is specified then the older \*(L"traditional\*(R" format is used instead. .IP "\fB\-\f(BIcipher\fB\fR" 4 .IX Item "-cipher" These options encrypt the private key with the supplied cipher. Any algorithm name accepted by \fBEVP_get_cipherbyname()\fR is acceptable such as \fBdes3\fR. .IP "\fB\-text\fR" 4 .IX Item "-text" Prints out the various public or private key components in plain text in addition to the encoded version. .IP "\fB\-text_pub\fR" 4 .IX Item "-text_pub" Print out only public key components even if a private key is being processed. .IP "\fB\-noout\fR" 4 .IX Item "-noout" Do not output the encoded version of the key. .IP "\fB\-pubin\fR" 4 .IX Item "-pubin" By default a private key is read from the input file: with this option a public key is read instead. .IP "\fB\-pubout\fR" 4 .IX Item "-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. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine (by its unique \fBid\fR string) will cause \fBpkey\fR 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. .IP "\fB\-check\fR" 4 .IX Item "-check" This option checks the consistency of a key pair for both public and private components. .IP "\fB\-pubcheck\fR" 4 .IX Item "-pubcheck" This option checks the correctness of either a public key or the public component of a key pair. .SH "EXAMPLES" .IX Header "EXAMPLES" To remove the pass phrase on an \s-1RSA\s0 private key: .PP .Vb 1 \& openssl pkey \-in key.pem \-out keyout.pem .Ve .PP To encrypt a private key using triple \s-1DES:\s0 .PP .Vb 1 \& openssl pkey \-in key.pem \-des3 \-out keyout.pem .Ve .PP To convert a private key from \s-1PEM\s0 to \s-1DER\s0 format: .PP .Vb 1 \& openssl pkey \-in key.pem \-outform DER \-out keyout.der .Ve .PP To print out the components of a private key to standard output: .PP .Vb 1 \& openssl pkey \-in key.pem \-text \-noout .Ve .PP To print out the public components of a private key to standard output: .PP .Vb 1 \& openssl pkey \-in key.pem \-text_pub \-noout .Ve .PP To just output the public part of a private key: .PP .Vb 1 \& openssl pkey \-in key.pem \-pubout \-out pubkey.pem .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBgenpkey\fR\|(1), \fBrsa\fR\|(1), \fBpkcs8\fR\|(1), \&\fBdsa\fR\|(1), \fBgenrsa\fR\|(1), \fBgendsa\fR\|(1) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2006\-2021 The OpenSSL Project Authors.
