If no command named I<XXX> exists, it +returns 0 (success) and prints B<no->I<XXX>; otherwise it returns 1 +and prints I<XXX>. In both cases, the output goes to B<stdout> and +nothing is printed to B<stderr>. 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 B<openssl> program. (B<no->I<XXX> is +not able to detect pseudo-commands such as B<quit>, +B<list->I<...>B<-commands>, or B<no->I<XXX> itself.) + +=head2 STANDARD COMMANDS + +=over 10 + +=item L<B<asn1parse>|asn1parse(1)> + +Parse an ASN.1 sequence. + +=item L<B<ca>|ca(1)> + +Certificate Authority (CA) Management. + +=item L<B<ciphers>|ciphers(1)> + +Cipher Suite Description Determination. + +=item L<B<crl>|crl(1)> + +Certificate Revocation List (CRL) Management. + +=item L<B<crl2pkcs7>|crl2pkcs7(1)> + +CRL to PKCS#7 Conversion. + +=item L<B<dgst>|dgst(1)> + +Message Digest Calculation. + +=item B<dh> + +Diffie-Hellman Parameter Management. +Obsoleted by L<B<dhparam>|dhparam(1)>. + +=item L<B<dsa>|dsa(1)> + +DSA Data Management. + +=item L<B<dsaparam>|dsaparam(1)> + +DSA Parameter Generation. + +=item L<B<enc>|enc(1)> + +Encoding with Ciphers. + +=item L<B<errstr>|errstr(1)> + +Error Number to Error String Conversion. + +=item L<B<dhparam>|dhparam(1)> + +Generation and Management of Diffie-Hellman Parameters. + +=item B<gendh> + +Generation of Diffie-Hellman Parameters. +Obsoleted by L<B<dhparam>|dhparam(1)>. + +=item L<B<gendsa>|gendsa(1)> + +Generation of DSA Parameters. + +=item L<B<genrsa>|genrsa(1)> + +Generation of RSA Parameters. + +=item L<B<ocsp>|ocsp(1)> + +Online Certificate Status Protocol utility. + +=item L<B<passwd>|passwd(1)> + +Generation of hashed passwords. + +=item L<B<pkcs12>|pkcs12(1)> + +PKCS#12 Data Management. + +=item L<B<pkcs7>|pkcs7(1)> + +PKCS#7 Data Management. + +=item L<B<rand>|rand(1)> + +Generate pseudo-random bytes. + +=item L<B<req>|req(1)> + +X.509 Certificate Signing Request (CSR) Management. + +=item L<B<rsa>|rsa(1)> + +RSA Data Management. + +=item L<B<rsautl>|rsautl(1)> + +RSA utility for signing, verification, encryption, and decryption. + +=item L<B<s_client>|s_client(1)> + +This implements a generic SSL/TLS client which can establish a transparent +connection to a remote server speaking SSL/TLS.

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. + +=over 10 + +=item B<pass:password> + +the actual password is B<password>. Since the password is visible +to utilities (like 'ps' under Unix) this form should only be used +where security is not important. + +=item B<env:var> + +obtain the password from the environment variable B<var>. 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. + +=item B<file:pathname> + +the first line of B<pathname> is the password. If the same B<pathname> +argument is supplied to B<-passin> and B<-passout> arguments then the first +line will be used for the input password and the next line for the output +password. B<pathname> need not refer to a regular file: it could for example +refer to a device or named pipe. + +=item B<fd:number> + +read the password from the file descriptor B<number>.
