pkeyparam
PKEYPARAM(1SSL) OpenSSL PKEYPARAM(1SSL)
NAME
pkeyparam - public key algorithm parameter processing tool
SYNOPSIS
openssl pkeyparam [-in filename] [-out filename] [-text] [-noout] [-engine id]
DESCRIPTION
The pkey command processes public or private keys. They can be converted between various forms and their components printed out.
COMMAND OPTIONS
-in filename
This specifies the input filename to read parameters from or standard input if this option is not specified.
-out filename
This specifies the output filename to write parameters to or standard output if this option is not specified.
-text
prints out the parameters in plain text in addition to the encoded version.
-noout
do not output the encoded version of the parameters.
-engine id
specifying an engine (by its unique id string) will cause pkeyparam 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.
EXAMPLE
Print out text version of parameters:
openssl pkeyparam -in param.pem -text
NOTES
There are no -inform or -outform options for this command because only PEM format is supported because the key type is determined by the
PEM headers.
