NAME

6       openssl-gendsa - generate a DSA private key from a set of parameters

SYNOPSIS

9       openssl gendsa [-help] [-out filename] [-passout arg] [-aes128]
10       [-aes192] [-aes256] [-aria128] [-aria192] [-aria256] [-camellia128]
11       [-camellia192] [-camellia256] [-des] [-des3] [-idea] [-verbose] [-rand
12       files] [-writerand file] [-engine id] [-provider name] [-provider-path
13       path] [-propquery propq] [paramfile]
14

DESCRIPTION

16       This command generates a DSA private key from a DSA parameter file
17       (which will be typically generated by the openssl-dsaparam(1) command).
18

OPTIONS

20       -help
21           Print out a usage message.
22
23       -out filename
24           Output the key to the specified file. If this argument is not
25           specified then standard output is used.
26
27       -passout arg
28           The passphrase used for the output file.  See
29           openssl-passphrase-options(1).
30
31       -aes128, -aes192, -aes256, -aria128, -aria192, -aria256, -camellia128,
32       -camellia192, -camellia256, -des, -des3, -idea
33           These options encrypt the private key with specified cipher before
34           outputting it. A pass phrase is prompted for.  If none of these
35           options is specified no encryption is used.
36
37           Note that all options must be given before the paramfile argument.
38           Otherwise they are ignored.
39
40       -verbose
41           Print extra details about the operations being performed.
42
43       -rand files, -writerand file
44           See "Random State Options" in openssl(1) for details.
45
46       -engine id
47           See "Engine Options" in openssl(1).  This option is deprecated.
48
49       paramfile
50           The DSA parameter file to use. The parameters in this file
51           determine the size of the private key. DSA parameters can be
52           generated and examined using the openssl-dsaparam(1) command.
53
54       -provider name
55       -provider-path path
56       -propquery propq
57           See "Provider Options" in openssl(1), provider(7), and property(7).

NOTES

60       DSA key generation is little more than random number generation so it
61       is much quicker that RSA key generation for example.
