+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+This command allows PKCS#12 files (sometimes referred to as
+\&\s-1PFX\s0 files) to be created and parsed. PKCS#12 files are used by several
+programs including Netscape, \s-1MSIE\s0 and \s-1MS\s0 Outlook.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+There are a lot of options the meaning of some depends of whether a PKCS#12 file
+is being created or parsed. By default a PKCS#12 file is parsed.
+A PKCS#12 file can be created by using the \fB\-export\fR option (see below).
+The PKCS#12 export encryption and \s-1MAC\s0 options such as \fB\-certpbe\fR and \fB\-iter\fR
+and many further options such as \fB\-chain\fR are relevant only with \fB\-export\fR.
+Conversely, the options regarding encryption of private keys when outputting
+PKCS#12 input are relevant only when the \fB\-export\fR option is not given.
+.PP
+The default encryption algorithm is \s-1AES\-256\-CBC\s0 with \s-1PBKDF2\s0 for key derivation.
+.PP
+When encountering problems loading legacy PKCS#12 files that involve,
+for example, \s-1RC2\-40\-CBC,\s0
+try using the \fB\-legacy\fR option and, if needed, the \fB\-provider\-path\fR option.
+.IP "\fB\-help\fR" 4
+.IX Item "-help"
+Print out a usage message.
+.IP "\fB\-passin\fR \fIarg\fR" 4
+.IX Item "-passin arg"
+The password source for the input, and for encrypting any private keys that
+are output.
+For more information about the format of \fBarg\fR
+see \fBopenssl\-passphrase\-options\fR\|(1).
+.IP "\fB\-passout\fR \fIarg\fR" 4
+.IX Item "-passout arg"
+The password source for output files.
+.IP "\fB\-password\fR \fIarg\fR" 4
+.IX Item "-password arg"
+With \fB\-export\fR, \fB\-password\fR is equivalent to \fB\-passout\fR,
+otherwise it is equivalent to \fB\-passin\fR.
+.IP "\fB\-twopass\fR" 4
+.IX Item "-twopass"
+Prompt for separate integrity and encryption passwords: most software
+always assumes these are the same so this option will render such
+PKCS#12 files unreadable. Cannot be used in combination with the options
+\&\fB\-password\fR, \fB\-passin\fR if importing from PKCS#12, or \fB\-passout\fR if exporting.
+.IP "\fB\-nokeys\fR" 4
+.IX Item "-nokeys"
+No private keys will be output.
+.IP "\fB\-nocerts\fR" 4
+.IX Item "-nocerts"
+No certificates will be output.
+.IP "\fB\-noout\fR" 4
+.IX Item "-noout"
+This option inhibits all credentials output,
+and so the input is just verified.
+.IP "\fB\-legacy\fR" 4
+.IX Item "-legacy"
+Use legacy mode of operation and automatically load the legacy provider.
+If OpenSSL is not installed system-wide,
+it is necessary to also use, for example, \f(CW\*(C`\-provider\-path ./providers\*(C'\fR
+or to set the environment variable \fB\s-1OPENSSL_MODULES\s0\fR
+to point to the directory where the providers can be found.
+.Sp
+In the legacy mode, the default algorithm for certificate encryption
+is \s-1RC2_CBC\s0 or 3DES_CBC depending on whether the \s-1RC2\s0 cipher is enabled
+in the build. The default algorithm for private key encryption is 3DES_CBC.
+If the legacy option is not specified, then the legacy provider is not loaded
+and the default encryption algorithm for both certificates and private keys is
+\&\s-1AES_256_CBC\s0 with \s-1PBKDF2\s0 for key derivation.

+Standard input is used by default.
+With the \fB\-export\fR option this is a file with certificates and a key,
+or a \s-1URI\s0 that refers to a key accessed via an engine.
+The order of credentials in a file doesn't matter but one private key and

+appear. Netscape ignores friendly names on other certificates whereas \s-1MSIE\s0
+displays them.
+.IP "\fB\-CSP\fR \fIname\fR" 4

+Write \fIname\fR as a Microsoft \s-1CSP\s0 name.
+The password source for the input, and for encrypting any private keys that
+are output.
+For more information about the format of \fBarg\fR
+see \fBopenssl\-passphrase\-options\fR\|(1).
+.IP "\fB\-LMK\fR" 4
+.IX Item "-LMK"
+Add the \*(L"Local Key Set\*(R" identifier to the attributes.
+.IP "\fB\-keyex\fR|\fB\-keysig\fR" 4
+.IX Item "-keyex|-keysig"
+Specifies that the private key is to be used for key exchange or just signing.
+This option is only interpreted by \s-1MSIE\s0 and similar \s-1MS\s0 software. Normally
+\&\*(L"export grade\*(R" software will only allow 512 bit \s-1RSA\s0 keys to be used for
+encryption purposes but arbitrary length keys for signing. The \fB\-keysig\fR
+option marks the key for signing only. Signing only keys can be used for
+S/MIME signing, authenticode (ActiveX control signing) and \s-1SSL\s0 client
+authentication, however, due to a bug only \s-1MSIE 5.0\s0 and later support
+the use of signing only keys for \s-1SSL\s0 client authentication.
+.IP "\fB\-keypbe\fR \fIalg\fR, \fB\-certpbe\fR \fIalg\fR" 4
+.IX Item "-keypbe alg, -certpbe alg"
+These options allow the algorithm used to encrypt the private key and
+certificates to be selected. Any PKCS#5 v1.5 or PKCS#12 \s-1PBE\s0 algorithm name
+can be used (see \*(L"\s-1NOTES\*(R"\s0 section for more information). If a cipher name
+(as output by \f(CW\*(C`openssl list \-cipher\-algorithms\*(C'\fR) is specified then it
+is used with PKCS#5 v2.0. For interoperability reasons it is advisable to only
+use PKCS#12 algorithms.
+.Sp
+Special value \f(CW\*(C`NONE\*(C'\fR disables encryption of the private key and certificates.
+.IP "\fB\-descert\fR" 4
+.IX Item "-descert"
+Encrypt the certificates using triple \s-1DES.\s0 By default the private
+key and the certificates are encrypted using \s-1AES\-256\-CBC\s0 unless
+the '\-legacy' option is used. If '\-descert' is used with the '\-legacy'
+then both, the private key and the certificates are encrypted using triple \s-1DES.\s0
+.IP "\fB\-macalg\fR \fIdigest\fR" 4
+.IX Item "-macalg digest"
+Specify the \s-1MAC\s0 digest algorithm. If not included \s-1SHA256\s0 will be used.
+.IP "\fB\-iter\fR \fIcount\fR" 4
+.IX Item "-iter count"
+This option specifies the iteration count for the encryption key and \s-1MAC.\s0 The
+default value is 2048.
+.Sp
+To discourage attacks by using large dictionaries of common passwords the
+algorithm that derives keys from passwords can have an iteration count applied
+to it: this causes a certain part of the algorithm to be repeated and slows it
+down. The \s-1MAC\s0 is used to check the file integrity but since it will normally
+have the same password as the keys and certificates it could also be attacked.
+.IP "\fB\-noiter\fR, \fB\-nomaciter\fR" 4
+.IX Item "-noiter, -nomaciter"
+By default both encryption and \s-1MAC\s0 iteration counts are set to 2048, using
+these options the \s-1MAC\s0 and encryption iteration counts can be set to 1, since
+this reduces the file security you should not use these options unless you
+really have to. Most software supports both \s-1MAC\s0 and encryption iteration counts.
+\&\s-1MSIE 4.0\s0 doesn't support \s-1MAC\s0 iteration counts so it needs the \fB\-nomaciter\fR
+option.
+.IP "\fB\-maciter\fR" 4
+.IX Item "-maciter"
+This option is included for compatibility with previous versions, it used
+to be needed to use \s-1MAC\s0 iterations counts but they are now used by default.
+.IP "\fB\-nomac\fR" 4
+.IX Item "-nomac"
+Do not attempt to provide the \s-1MAC\s0 integrity. This can be useful with the \s-1FIPS\s0
+provider as the \s-1PKCS12 MAC\s0 requires \s-1PKCS12KDF\s0 which is not an approved \s-1FIPS\s0
+algorithm and cannot be supported by the \s-1FIPS\s0 provider.
+.SH "NOTES"
+.IX Header "NOTES"
+Although there are a large number of options most of them are very rarely
+used. For PKCS#12 file parsing only \fB\-in\fR and \fB\-out\fR need to be used
+for PKCS#12 file creation \fB\-export\fR and \fB\-name\fR are also used.
+.PP
+If none of the \fB\-clcerts\fR, \fB\-cacerts\fR or \fB\-nocerts\fR options are present
+then all certificates will be output in the order they appear in the input
+PKCS#12 files. There is no guarantee that the first certificate present is
+the one corresponding to the private key.
+Certain software which tries to get a private key and the corresponding
+certificate might assume that the first certificate in the file is the one
+corresponding to the private key, but that may not always be the case.
+Using the \fB\-clcerts\fR option will solve this problem by only
+outputting the certificate corresponding to the private key. If the \s-1CA\s0
+certificates are required then they can be output to a separate file using
+the \fB\-nokeys\fR \fB\-cacerts\fR options to just output \s-1CA\s0 certificates.

+The \fB\-keypbe\fR and \fB\-certpbe\fR algorithms allow the precise encryption
+algorithms for private keys and certificates to be specified. Normally
+the defaults are fine but occasionally software can't handle triple \s-1DES\s0
+encrypted private keys, then the option \fB\-keypbe\fR \fI\s-1PBE\-SHA1\-RC2\-40\s0\fR can
+be used to reduce the private key encryption to 40 bit \s-1RC2. A\s0 complete
+description of all algorithms is contained in \fBopenssl\-pkcs8\fR\|(1).

+Prior 1.1 release passwords containing non-ASCII characters were encoded
+in non-compliant manner, which limited interoperability, in first hand
+with Windows. But switching to standard-compliant password encoding
+poses problem accessing old data protected with broken encoding. For
+this reason even legacy encodings is attempted when reading the
+data. If you use PKCS#12 files in production application you are advised
+to convert the data, because implemented heuristic approach is not
+MT-safe, its sole goal is to facilitate the data upgrade with this
+command.
