OpenSSL Command to List All Commands
How to list all commands in OpenSSL? I don't remember exactly what is the command to generate a CSR.
✍: FYIcenter.com
Interestingly, there is no OpenSSL command to list all commands supported in OpenSSL.
And there is no "help" command.
However, if you enter "help" as a command, OpenSSL will return you an error message saying "'help' is an invalid command" with a list of valid commands to help you to enter a valid command as you see in the example below:
OpenSSL> help openssl:Error: 'help' is an invalid command. Standard commands asn1parse ca ciphers cms crl crl2pkcs7 dgst dh dhparam dsa dsaparam ec ecparam enc engine errstr gendh gendsa genpkey genrsa nseq ocsp passwd pkcs12 pkcs7 pkcs8 pkey pkeyparam pkeyutl prime rand req rsa rsautl s_client s_server s_time sess_id smime speed spkac srp ts verify version x509 Message Digest commands (see the `dgst' command for more details) md4 md5 mdc2 rmd160 sha sha1 Cipher commands (see the `enc' command for more details) aes-128-cbc aes-128-ecb aes-192-cbc aes-192-ecb aes-256-cbc aes-256-ecb base64 bf bf-cbc bf-cfb bf-ecb bf-ofb camellia-128-cbc camellia-128-ecb camellia-192-cbc camellia-192-ecb camellia-256-cbc camellia-256-ecb cast cast-cbc cast5-cbc cast5-cfb cast5-ecb cast5-ofb des des-cbc des-cfb des-ecb des-ede des-ede-cbc des-ede-cfb des-ede-ofb des-ede3 des-ede3-cbc des-ede3-cfb des-ede3-ofb des-ofb des3 desx idea idea-cbc idea-cfb idea-ecb idea-ofb rc2 rc2-40-cbc rc2-64-cbc rc2-cbc rc2-cfb rc2-ecb rc2-ofb rc4 rc4-40 seed seed-cbc seed-cfb seed-ecb seed-ofb
So entering "help" or any random string is a way to list all commands supported in OpenSSL.
