What commands are supported in OpenSSL?

Here is a complete list of commands supported in OpenSSL:

STANDARD COMMANDS

• asn1parse - Parse an ASN.1 sequence.
• ca - Certificate Authority (CA) Management.
• ciphers - Cipher Suite Description Determination.
• cms - CMS (Cryptographic Message Syntax) utility
• crl - Certificate Revocation List (CRL) Management.
• crl2pkcs7 - CRL to PKCS#7 Conversion.
• dgst - Message Digest Calculation.
• dh - Diffie-Hellman Parameter Management. Obsoleted by dhparam.
• dhparam - Generation and Management of Diffie-Hellman Parameters. Superseded by genpkey and pkeyparam
• dsa - DSA Data Management.
• dsaparam - DSA Parameter Generation and Management. Superseded by genpkey and pkeyparam
• ec - EC (Elliptic curve) key processing
• ecparam - EC parameter manipulation and generation
• enc - Encoding with Ciphers.
• engine - Engine (loadble module) information and manipulation.
• errstr - Error Number to Error String Conversion.
• gendh - Generation of Diffie-Hellman Parameters. Obsoleted by dhparam.
• gendsa - Generation of DSA Private Key from Parameters. Superseded by genpkey and pkey
• genpkey - Generation of Private Key or Parameters.
• genrsa - Generation of RSA Private Key. Superceded by genpkey.
• nseq - Create or examine a netscape certificate sequence
• ocsp - Online Certificate Status Protocol utility.
• passwd - Generation of hashed passwords.
• pkcs12 - PKCS#12 Data Management.
• pkcs7 - PKCS#7 Data Management.
• pkey - Public and private key management.
• pkeyparam - Public key algorithm parameter management.
• pkeyutl - Public key algorithm cryptographic operation utility.
• rand - Generate pseudo-random bytes.
• req - PKCS#10 X.509 Certificate Signing Request (CSR) Management.
• rsa - RSA key management.
• rsautl - RSA utility for signing, verification, encryption, and decryption. Superseded by pkeyutl
• s_client - This implements a generic SSL/TLS client which can establish a transparent connection to a remote server speaking SSL/TLS. It's intended for testing purposes only and provides only rudimentary interface functionality but internally uses mostly all functionality of the OpenSSL ssl library.
• s_server - This implements a generic SSL/TLS server which accepts connections from remote clients speaking SSL/TLS. It's intended for testing purposes only and provides only rudimentary interface functionality but internally uses mostly all functionality of the OpenSSL ssl library. It provides both an own command line oriented protocol for testing SSL functions and a simple HTTP response facility to emulate an SSL/TLS-aware webserver.
• s_time - SSL Connection Timer.
• sess_id - SSL Session Data Management.
• smime - S/MIME mail processing.
• speed - Algorithm Speed Measurement.
• spkac - SPKAC printing and generating utility
• ts - Time Stamping Authority tool (client/server)
• verify - X.509 Certificate Verification.
• version - OpenSSL Version Information.
• x509 - X.509 Certificate Data Management.

MESSAGE DIGEST COMMANDS

• md2 - MD2 Digest
• md5 - MD5 Digest
• mdc2 - MDC2 Digest
• rmd160 - RMD-160 Digest
• sha - SHA Digest
• sha1 - SHA-1 Digest
• sha224 - SHA-224 Digest
• sha256 - SHA-256 Digest
• sha384 - SHA-384 Digest
• sha512 - SHA-512 Digest

ENCODING AND CIPHER COMMANDS

• base64 - Base64 Encoding
• bf bf-cbc bf-cfb bf-ecb bf-ofb - Blowfish Cipher
• cast cast-cbc - CAST Cipher

• des des-cbc des-cfb des-ecb des-ede des-ede-cbc des-ede-cfb des-ede-ofb des-ofb - DES Cipher
• des3 desx des-ede3 des-ede3-cbc des-ede3-cfb des-ede3-ofb - Triple-DES Cipher
• idea idea-cbc idea-cfb idea-ecb idea-ofb - IDEA Cipher
• rc2 rc2-cbc rc2-cfb rc2-ecb rc2-ofb - RC2 Cipher
• rc4 - RC4 Cipher
• rc5 rc5-cbc rc5-cfb rc5-ecb rc5-ofb - RC5 Cipher
