NAME¶
openssl-pkeyparam, pkeyparam - public key algorithm parameter processing tool
SYNOPSIS¶
openssl pkeyparam [-help] [-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.
OPTIONS¶
- -help
- Print out a usage message.
- -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.
