AmigaOS 4.0 - About OS4 - Commands

OPENSSL AmigaDOS
Purpose: Cryptography toolkit command line tool.
Format: OPENSSL <command> [<command options>] [<command arguments>]
OPENSSL <list-standard-commands | list-message-digest-commands | list-cipher-commands>
OPENSSL no-*XXX* [<arbitrary options>]
Template: openssl [ list-standard-commands | list-message-digest-commands | list-cipher-commands ] openssl DEVICE/A/M, FROM/K, QUIET/S, REPLACE/S, STARTUP/K/F
Path: C:OPENSSL
OPENSSL is a cryptography toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) network protocols and related cryptography standards required by them.

NOTE: While OPENSSL is delivered as part of the AmigaOS 4.0 installation, it will not run until the AmiSSL layer has also been installed. This can be downloaded from OS4Ddepot.

The OPENSSL program is a command line tool for using the various cryptography functions of OpenSSL's crypto library from the shell. It can be used for

  • Creation of RSA, DH and DSA key parameters
  • Creation of X.509 certificates, CSRs and CRLs
  • Calculation of Message Digests
  • Encryption and Decryption with Ciphers
  • SSL/TLS Client and Server Tests
  • Handling of S/MIME signed or encrypted mail
The OPENSSL program provides a rich variety of <command> options, each of which often has a wealth of <command options> and <command arguments>.

The pseudo-commands list-standard-commands, list-message-digest-commands, and list-cipher-commands 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 OPENSSL utility.

The pseudo-command no-*XXX* tests whether a command of the specified name is available. If no command named *XXX* exists, it returns 0 (success) and prints no-*XXX*; otherwise it returns 1 and prints *XXX*. In both cases, the output goes to stdout and nothing is printed to 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 OPENSSL program. (no-*XXX* is not able to detect pseudo-commands such as quit, list-*...*-commands, or no-*XXX* itself.)

STANDARD COMMANDS SUMMARY
The following list is a summary of the Standard Commands:

asn1parse Parse an ASN.1 sequence.
ca Certificate Authority (CA) Management.
ciphers Cipher Suite Description Determination.
crl Certificate Revocation List (CRL) Management.
crl2pkcs7 CRL to PKCS#7 Conversion.
dgst Message Digest Calculation.
dh Diffie-Hellman Parameter Management. Obsoleted by dhparam.
dsa DSA Data Management.
dsaparam DSA Parameter Generation.
enc Encoding with Ciphers.
errstr Error Number to Error String Conversion.
dhparam Generation and Management of Diffie-Hellman Parameters.
gendh Generation of Diffie-Hellman Parameters. Obsoleted by dhparam.
gendsa Generation of DSA Parameters.
genrsa Generation of RSA Parameters.
ocsp Online Certificate Status Protocol utility.
passwd Generation of hashed passwords.
pkcs12 PKCS#12 Data Management.
pkcs7 PKCS#7 Data Management.
rand Generate pseudo-random bytes.
req X.509 Certificate Signing Request (CSR) Management.
rsa RSA Data Management.
rsautl RSA utility for signing, verification, encryption, and decryption.
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.
verify X.509 Certificate Verification.
version OpenSSL Version Information.
x509 X.509 Certificate Data Management.

PASS PHRASE ARGUMENTS
Several commands accept password arguments, typically using -passin and -passout for input and output passwords respectively. 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.
pass:password the actual password is password. Since the password is visible to utilities (like 'ps' under Unix) this form should only be used where security is not important.
env:var obtain the password from the environment variable 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.
file:pathname the first line of pathname is the password. If the same pathname argument is supplied to -passin and -passout arguments then the first line will be used for the input password and the next line for the output password. pathname need not refer to a regular file; it could for example refer to a device or named pipe.
fd:number read the password from the file descriptor number. This can be used to send the data via a pipe for example.
stdin read the password from standard input.
