NAME

6       openssl-pkeyparam - public key algorithm parameter processing command
7

SYNOPSIS

9       openssl pkeyparam [-help] [-in filename] [-out filename] [-text]
10       [-noout] [-check] [-engine id] [-provider name] [-provider-path path]
11       [-propquery propq]
12

DESCRIPTION

14       This command processes public key algorithm parameters.  They can be
15       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       -check
37           This option checks the correctness of parameters.
38
39       -engine id
40           See "Engine Options" in openssl(1).  This option is deprecated.
41
42       -provider name
43       -provider-path path
44       -propquery propq
45           See "Provider Options" in openssl(1), provider(7), and property(7).
46

EXAMPLES

48       Print out text version of parameters:
49
50        openssl pkeyparam -in param.pem -text
51

NOTES

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