PKEYPARAM(1) OpenSSL PKEYPARAM(1) NNAAMMEE pkeyparam - public key algorithm parameter processing tool SSYYNNOOPPSSIISS ooppeennssssll ppkkeeyyppaarraamm [--iinn ffiilleennaammee] [--oouutt ffiilleennaammee] [--tteexxtt] [--nnoooouutt] [--eennggiinnee iidd] DDEESSCCRRIIPPTTIIOONN The ppkkeeyy command processes public or private keys. They can be con- verted between various forms and their components printed out. CCOOMMMMAANNDD OOPPTTIIOONNSS --iinn ffiilleennaammee This specifies the input filename to read parameters from or stan- dard input if this option is not specified. --oouutt ffiilleennaammee This specifies the output filename to write parameters to or stan- dard output if this option is not specified. --tteexxtt prints out the parameters in plain text in addition to the encoded version. --nnoooouutt do not output the encoded version of the parameters. --eennggiinnee iidd specifying an engine (by its unique iidd string) will cause ppkkeeyyppaarraamm to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms. EEXXAAMMPPLLEE Print out text version of parameters: openssl pkeyparam -in param.pem -text NNOOTTEESS There are no --iinnffoorrmm or --oouuttffoorrmm options for this command because only PEM format is supported because the key type is determined by the PEM headers.
