OPENSSL-GENDSA(1ossl) OpenSSL OPENSSL-GENDSA(1ossl) NAME openssl-gendsa - generate a DSA private key from a set of parameters SYNOPSIS openssl gendsa [-help] [-out filename] [-passout arg] [-aes128] [-aes192] [-aes256] [-aria128] [-aria192] [-aria256] [-camellia128] [-camellia192] [-camellia256] [-des] [-des3] [-idea] [-verbose] [-quiet] [-rand files] [-writerand file] [-provider name] [-provider-path path] [-provparam [name:]key=value] [-propquery propq] [paramfile] DESCRIPTION This command generates a DSA private key from a DSA parameter file (which will be typically generated by the openssl-dsaparam(1) command). OPTIONS -help Print out a usage message. -out filename Output the key to the specified file. If this argument is not specified then standard output is used. -passout arg The passphrase used for the output file. See openssl-passphrase-op- tions(1). -aes128, -aes192, -aes256, -aria128, -aria192, -aria256, -camellia128, -camellia192, -camellia256, -des, -des3, -idea These options encrypt the private key with specified cipher before out- putting it. A pass phrase is prompted for. If none of these options is specified no encryption is used. Note that all options must be given before the paramfile argument. -verbose Print extra details about the operations being performed. -quiet Print fewer details about the operations being performed, which may be handy during batch scripts and pipelines. -rand files, -writerand file See "Random State Options" in openssl(1) for details. paramfile The DSA parameter file to use. The parameters in this file determine the size of the private key. DSA parameters can be generated and exam- ined using the openssl-dsaparam(1) command. -provider name -provider-path path -provparam [name:]key=value -propquery propq See "Provider Options" in openssl(1), provider(7), and property(7). NOTES DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example.
