NAME

6       openssl-pkeyparam, pkeyparam - public key algorithm parameter
7       processing tool
8

SYNOPSIS

10       openssl pkeyparam [-help] [-in filename] [-out filename] [-text]
11       [-noout] [-engine id] [-check]
12

DESCRIPTION

14       The pkeyparam command processes public key algorithm parameters.  They
15       can be checked for correctness and their components printed out.
16

OPTIONS

18       -help
19           Print out a usage message.
20
21       -in filename
22           This specifies the input filename to read parameters from or
23           standard input if this option is not specified.
24
25       -out filename
26           This specifies the output filename to write parameters to or
27           standard output if this option is not specified.
28
29       -text
30           Prints out the parameters in plain text in addition to the encoded
31           version.
32
33       -noout
34           Do not output the encoded version of the parameters.
35
36       -engine id
37           Specifying an engine (by its unique id string) will cause pkeyparam
38           to attempt to obtain a functional reference to the specified
39           engine, thus initialising it if needed. The engine will then be set
40           as the default for all available algorithms.
41
42       -check
43           This option checks the correctness of parameters.
44

EXAMPLES

46       Print out text version of parameters:
47
48        openssl pkeyparam -in param.pem -text
49

NOTES

51       There are no -inform or -outform options for this command because only
52       PEM format is supported because the key type is determined by the PEM
53       headers.
