NAME
openssl-pkeyparam - public key algorithm parameter processing command
SYNOPSIS
opensslpkeyparam [-help] [-infilename] [-outfilename] [-text] [-noout] [-check] [-engineid] [-providername] [-provider-pathpath] [-provparam[name:]key=value] [-propquerypropq]
DESCRIPTION
This command processes public key algorithm parameters. They can be checked for correctness and their components printed out.
OPTIONS
- -help
Print out a usage message.
- -infilename
This specifies the input file to read parameters from or standard input if this option is not specified.
- -outfilename
This specifies the output filename to write parameters to or standard output if this option is not specified. The output filename can be the same as the input filename, which leads to replacing the file contents. Note that file I/O is not atomic. The output file is truncated and then written.
- -text
Prints out the parameters in plain text in addition to the encoded version.
- -noout
Do not output the encoded version of the parameters.
- -check
This option checks the correctness of parameters.
- -engineid
See "Engine Options" in openssl(1). This option is deprecated.
- -providername
- -provider-pathpath
- -provparam[name:]key=value
- -propquerypropq
See "Provider Options" in openssl(1), provider(7), and property(7).
EXAMPLES
Print out text version of parameters:
openssl pkeyparam -in param.pem -textNOTES
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.
