It can be used for .PP .Vb 8 \& o Creation and management of private keys, public keys and parameters \& o Public key cryptographic operations \& o Creation of X.509 certificates, CSRs and CRLs \& o Calculation of Message Digests \& o Encryption and Decryption with Ciphers \& o SSL/TLS Client and Server Tests \& o Handling of S/MIME signed or encrypted mail \& o Time Stamp requests, generation and verification .Ve .SH "COMMAND SUMMARY" .IX Header "COMMAND SUMMARY" The \fBopenssl\fR program provides a rich variety of commands (\fIcommand\fR in the \&\s-1SYNOPSIS\s0 above), each of which often has a wealth of options and arguments (\fIcommand_opts\fR and \fIcommand_args\fR in the \s-1SYNOPSIS\s0). .PP The pseudo-commands \fBlist-standard-commands\fR, \fBlist-message-digest-commands\fR, and \fBlist-cipher-commands\fR output a list (one entry per line) of the names of all standard commands, message digest commands, or cipher commands, respectively, that are available in the present \fBopenssl\fR utility. .PP The pseudo-commands \fBlist-cipher-algorithms\fR and \&\fBlist-message-digest-algorithms\fR list all cipher and message digest names, one entry per line. Aliases are listed as: .PP .Vb 1 \& from => to .Ve .PP The pseudo-command \fBlist-public-key-algorithms\fR lists all supported public key algorithms. .PP The pseudo-command \fBno\-\fR\fI\s-1XXX\s0\fR tests whether a command of the specified name is available. If no command named \fI\s-1XXX\s0\fR exists, it returns 0 (success) and prints \fBno\-\fR\fI\s-1XXX\s0\fR; otherwise it returns 1 and prints \fI\s-1XXX\s0\fR. In both cases, the output goes to \fBstdout\fR and nothing is printed to \fBstderr\fR. Additional command line arguments are always ignored. Since for each cipher there is a command of the same name, this provides an easy way for shell scripts to test for the availability of ciphers in the \fBopenssl\fR program. (\fBno\-\fR\fI\s-1XXX\s0\fR is not able to detect pseudo-commands such as \fBquit\fR, \&\fBlist\-\fR\fI...\fR\fB\-commands\fR, or \fBno\-\fR\fI\s-1XXX\s0\fR itself.) .SS "\s-1STANDARD COMMANDS\s0" .IX Subsection "STANDARD COMMANDS" .IP "\fBasn1parse\fR" 10 .IX Item "asn1parse" Parse an \s-1ASN.1\s0 sequence. .IP "\fBca\fR" 10 .IX Item "ca" Certificate Authority (\s-1CA\s0) Management. .IP "\fBciphers\fR" 10 .IX Item "ciphers" Cipher Suite Description Determination. .IP "\fBcms\fR" 10 .IX Item "cms" \&\s-1CMS\s0 (Cryptographic Message Syntax) utility .IP "\fBcrl\fR" 10 .IX Item "crl" Certificate Revocation List (\s-1CRL\s0) Management. .IP "\fBcrl2pkcs7\fR" 10 .IX Item "crl2pkcs7" \&\s-1CRL\s0 to PKCS#7 Conversion. .IP "\fBdgst\fR" 10 .IX Item "dgst" Message Digest Calculation. .IP "\fBdh\fR" 10 .IX Item "dh" Diffie-Hellman Parameter Management.

These allow the password to be obtained from a variety of sources. Both of these options take a single argument whose format is described below. If no password argument is given and a password is required then the user is prompted to enter one: this will typically be read from the current terminal with echoing turned off. .IP "\fBpass:password\fR" 10 .IX Item "pass:password" the actual password is \fBpassword\fR. Since the password is visible to utilities (like 'ps' under Unix) this form should only be used where security is not important. .IP "\fBenv:var\fR" 10 .IX Item "env:var" obtain the password from the environment variable \fBvar\fR. Since the environment of other processes is visible on certain platforms (e.g. ps under certain Unix OSes) this option should be used with caution. .IP "\fBfile:pathname\fR" 10 .IX Item "file:pathname" the first line of \fBpathname\fR is the password. If the same \fBpathname\fR argument is supplied to \fB\-passin\fR and \fB\-passout\fR arguments then the first line will be used for the input password and the next line for the output password. \fBpathname\fR need not refer to a regular file: it could for example refer to a device or named pipe. .IP "\fBfd:number\fR" 10 .IX Item "fd:number" read the password from the file descriptor \fBnumber\fR. This can be used to send the data via a pipe for example. .IP "\fBstdin\fR" 10 .IX Item "stdin" read the password from standard input. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBasn1parse\fR\|(1), \fBca\fR\|(1), \fBconfig\fR\|(5), \&\fBcrl\fR\|(1), \fBcrl2pkcs7\fR\|(1), \fBdgst\fR\|(1), \&\fBdhparam\fR\|(1), \fBdsa\fR\|(1), \fBdsaparam\fR\|(1), \&\fBenc\fR\|(1), \fBgendsa\fR\|(1), \fBgenpkey\fR\|(1), \&\fBgenrsa\fR\|(1), \fBnseq\fR\|(1), \fBopenssl\fR\|(1), \&\fBpasswd\fR\|(1), \&\fBpkcs12\fR\|(1), \fBpkcs7\fR\|(1), \fBpkcs8\fR\|(1), \&\fBrand\fR\|(1), \fBreq\fR\|(1), \fBrsa\fR\|(1), \&\fBrsautl\fR\|(1), \fBs_client\fR\|(1), \&\fBs_server\fR\|(1), \fBs_time\fR\|(1), \&\fBsmime\fR\|(1), \fBspkac\fR\|(1), \&\fBverify\fR\|(1), \fBversion\fR\|(1), \fBx509\fR\|(1), \&\fBcrypto\fR\|(3), \fBssl\fR\|(3), \fBx509v3_config\fR\|(5) .SH "HISTORY" .IX Header "HISTORY" The \fBopenssl\fR\|(1) document appeared in OpenSSL 0.9.2.
