NAME
pkeyparam - public key algorithm parameter processing tool
LIBRARY
libcrypto, -lcrypto
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.
