gendsa(1openssl) OpenSSL gendsa(1openssl)NAME
gendsa - generate a DSA private key from a set of parameters
SYNOPSIS
openssl gendsa [-out filename] [-des] [-des3] [-idea] [-rand file(s)] [-engine id] [paramfile]
DESCRIPTION
The gendsa command generates a DSA private key from a DSA parameter file (which will be typically generated by the openssl dsaparam com-
mand).
OPTIONS
-des|-des3|-idea
These options encrypt the private key with the DES, triple DES, or the IDEA ciphers respectively before outputting it. A pass phrase is
prompted for. If none of these options is specified no encryption is used.
-rand file(s)
a file or files containing random data used to seed the random number generator, or an EGD socket (see RAND_egd(3)). Multiple files
can be specified separated by a OS-dependent character. The separator is ; for MS-Windows, , for OpenVMS, and : for all others.
-engine id
specifying an engine (by it's unique id string) will cause req 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.
paramfile
This option specifies the DSA parameter file to use. The parameters in this file determine the size of the private key. DSA parameters
can be generated and examined using the openssl dsaparam command.
NOTES
DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example.

Hi,
I want to encrypt a unix file using the des3 algorithm. Seems that there are no standard unix utilities readily available. Can you please suggest how I can encrypt a unix file using des3 ? (2 Replies)
Hey all, i have an application i am developing and i would like to use the
OpenSSL des3 encryption, the only problem i am having is when i need to input the second key verification. Heres what i have so far
openssl des3 -salt -in /tmp -out pwenc.z | echo 1111
usually for password verification... (0 Replies)
